Beach dunes are usually made of quartz. The option C is correct.
What is a quartz?Corresponds to a common mineral that is found in many types of rocks, including granite, sandstone, and quartzite. When rocks containing quartz are weathered and eroded, the quartz grains are carried by wind, water, and ice to form sand.
Therefore, over time, the sand accumulates and is shaped by wind and waves to form beach dunes. While other minerals such as calcium carbonate, clay, and marble may be present in beach dunes, quartz is the most common mineral that makes up the majority of the sand.

a. socialist system to a communist system
b. free enterprise system to a socialist system
c. socialist system to a free enterprise
d. communist system to a free enterprise system
Answer:
Explanation:
c. socialist system to a free enterprise system. In the early 1990s, Russia underwent significant economic and political changes, transitioning from a socialist system to a market-oriented, free enterprise system. This period of transition, often referred to as "shock therapy," involved the privatization of state-owned industries, the liberalization of trade and investment policies, and the deregulation of markets. This transition was a challenging period for many Russians, as they faced significant economic and social upheaval. However, it also paved the way for the development of a more dynamic and diverse economy in Russia, with increased opportunities for entrepreneurship and innovation.

Who does climate change affect in Toronto?
Answer:
Climate change is expected to make Toronto's weather hotter, wetter and more extreme in the years to come. Fossil fuels are by far the largest contributor to global climate change, accounting for more than 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions.
The points E,F,G and H all lie on the same line segment, in that order, such that the ratio of RF:FG:GH is equal to 4:1:5. If EH = 10, find EG.
As line segment EG will always equal 10 minus a multiple of RH, we may conclude that it will change depending on the value of RH.
How is length of the line EG determined?Let's utilize the ratio of RF:FG:GH, which is 4:1:5, to demonstrate what would happen if we set RF equal to 4x while setting FG equal to x and GH equal to 5x.
The distance between E and H is equal to the sum of the distances between E and G and G and H since the locations E, F, G, and H are now known to be collinear. In other words, we can construct the equation shown below:
EG + GH = EH
Adding the values we are familiar with results in:
10 = EG + 5x
By deducting 5x from both sides, we may isolate the variable EG and find it:
10 - 5x = EG
We need to know the value of x in order to solve for EG. The fact that RF:FG:GH has a 4:1:5 ratio allows us to create the following equation:
RF + FG + GH = RH = 4x + x + 5x
If we simplify, we get:
10x = RH
We can't directly solve for x because we don't know the value of RH. Yet given that the ratio of RF:FG:GH is 4:1:5, we can infer that RF + FG is equivalent to 4/5 of RH.
FG + RF = (4/5)RH
Adding the values we are familiar with results in:
4x + x = (4/5)RH
If we simplify, we get:
5x = (4/5)RH
The result of multiplying both sides by 5/4 is:
x = (1/4)RH
Now that we have this value of x, we can enter it into the equation we created earlier:
10 - 5x = EG
Inputting x = (1/4)RH results in:
10 - 5(1/4)RH = EG
If we simplify, we get:
EG = 10 - (5/4)RH
RH may be valuable, but we are not in need of it. The only thing we need to know is that EG = 10 - a multiple of RH. As EG will always equal 10 minus a multiple of RH, we may conclude that it will change depending on the value of RH.

you have observed that there are variation in your environment in relation to natural, culture nada social phenomenon . Example all vegetation kinds are not the same . Geography is the study of aerial differentiation. write for or against the motion
Answer:
Explanation:
For the motion:
Geography is the study of spatial differentiation in the environment, including both physical and human phenomena. This differentiation can be observed in a variety of natural, cultural, and social phenomena. For example, the distribution of vegetation types varies depending on factors such as climate, topography, and soil type. Different regions may be characterized by different types of forests, grasslands, or deserts.
Similarly, geography helps us understand the distribution of cultural and social phenomena. For example, the distribution of languages, religions, and cultural practices can vary from region to region, and can be influenced by factors such as historical migration patterns, trade networks, and political boundaries.
In addition, geography is also concerned with the study of environmental processes and how they interact with human activities. This includes phenomena such as climate change, natural disasters, and land use change. By studying these processes, geographers can help identify solutions to mitigate their impacts and improve the sustainability of human societies.
Against the motion:
While it is true that there are variations in the environment related to natural, cultural, and social phenomena, this alone does not define the entire scope of geography. Geography is a multidisciplinary field that encompasses many different topics and approaches, and cannot be reduced to just the study of spatial differentiation.
For example, geography also includes the study of physical processes such as plate tectonics, erosion, and weathering, as well as the interactions between physical and human systems. Geography can also involve the use of quantitative methods such as GIS and remote sensing, as well as qualitative approaches such as ethnography and participatory mapping.
Therefore, while the study of spatial differentiation is an important aspect of geography, it is only one of many different areas of inquiry within the discipline.

Whitehall is the correct formula to find the area of triangle AED
Answer: area = 1/2 * base * height.
In other words, 1 2bh
Explanation: The formula for the area of a triangle is a 1 2bh
Finding area of triangles. To find a triangle's area, use the formula area = 1/2 * base * height. Choose a side to use for the base, and find the height of the triangle from that base. Then, plug in the measurements you have for the base and height into the formula.
A triangle has sides of length 5 ft, 9 ft, and 13 ft.
What is the measure of the angle opposite the side that is 9 ft long? Round to the nearest degree.
Answer:
To find the measure of the angle opposite the side that is 9 ft long, we can use the law of cosines, which states that c^2 = a^2 + b^2 - 2ab cos(C), where a, b, and c are the lengths of the sides of a triangle, and C is the angle opposite the side of length c.
In this case, a = 5 ft, b = 13 ft, and c = 9 ft. We want to find the measure of the angle C opposite the side of length c = 9 ft.
Plugging in the values, we get:
9^2 = 5^2 + 13^2 - 2(5)(13)cos(C)
81 = 194 - 130cos(C)
130cos(C) = 113
cos(C) = 113/130
C = cos^-1(113/130)
Using a calculator, we get:
C ≈ 38.2 degrees
Therefore, the measure of the angle opposite the side that is 9 ft long is approximately 38 degrees.

. If its height is 21 units, find its radius.
The formula for the volume of a right cone is V = (1/3)πr^2h, where r is the radius and h is the height.
We are given that V = 252π/3 and h = 21. Substituting these values in the formula, we get:
252π/3 = (1/3)πr^2(21)
Canceling the 3's and π on both sides, we get:
84 = 7r^2
Dividing both sides by 7, we get:
r^2 = 12
Taking the square root of both sides, we get:
r = √12 = 2√3
Therefore, the radius of the cone is 2√3 units.

Jackson loves to take day trips during weekends. Last weekend, he drove 80 miles to Crabclaw Beach. He used 4 gallons of gas to get there. This weekend, he will drive 100 miles to get to Mount Highmore.
If he uses gas at the same rate, how many gallons of gas will Jackson use to get to Mount Highmore?
gallons
Answer:
Explanation:
If Jackson used 4 gallons of gas to drive 80 miles to Crabclaw Beach, we can calculate his gas mileage as follows:
Gas mileage = distance / gas used
Gas mileage = 80 miles / 4 gallons
Gas mileage = 20 miles per gallon
Using this gas mileage, we can calculate how many gallons of gas Jackson will use to drive 100 miles to Mount Highmore:
Gas used = distance / gas mileage
Gas used = 100 miles / 20 miles per gallon
Gas used = 5 gallons
Therefore, Jackson will use 5 gallons of gas to get to Mount Highmore if he uses gas at the same rate as he did for his trip to Crabclaw Beach.

Geography is the study of areal differentiation." Discuss with examples
Answer:
Explanation:
Geography is the study of areal differentiation, which refers to the examination of differences and variations between various regions or areas. This involves analyzing the physical, biological, and human factors that contribute to the uniqueness of a place or region.
Physical geography is one of the branches of geography that examines the natural environment, including landforms, climate, vegetation, and water bodies. For example, the Great Rift Valley in Africa is a unique physical feature that has been shaped by tectonic and volcanic activity, resulting in a distinctive landscape with steep cliffs, deep gorges, and flat plains.
Human geography, on the other hand, focuses on the social and cultural aspects of human life, including population, economics, politics, and religion. For example, the cultural differences between different regions in the world can be seen in their language, customs, and beliefs. The Middle East, for instance, is characterized by a strong religious tradition and a long history of conflict, while Southeast Asia is known for its diverse ethnic groups and unique cultural practices.
Geographers also study the interactions between human and natural systems, such as how human activities affect the environment and how the environment influences human activities. For example, the Amazon rainforest in South America is not only a unique natural environment with rich biodiversity, but it is also home to indigenous peoples who have developed sustainable ways of life that are closely linked to the ecosystem.
Overall, the study of areal differentiation in geography provides insight into the complex interactions between physical and human systems and helps us better understand the diversity and uniqueness of different regions around the world.
Determine the location of a ship when the Sun is at the highest position in the sky (noon) when the time at Prime Meridian (Greenwich is as follows). Hint: Look at the example and read the explanation in Module Outlines. Show your work. Write your answers and calculations in the text box below.
1. Time 13:00 in Greenwich, England (1 PM)
2. Time 10:00 in Greenwich, England (10 AM)
3. Midnight (24:00) or 12:00 AM
4. Noon (12:00) or 12:00 PM
Answer:
Explanation:
To determine the location of a ship when the Sun is at the highest position in the sky (noon), we need to use a process called celestial navigation. This involves measuring the altitude of the Sun above the horizon at local noon, and then using this information to calculate the ship's latitude and longitude.
Assuming that we have the necessary instruments and data, the process would look something like this:
Time 13:00 in Greenwich, England (1 PM)
Assuming that the ship is located in a time zone that is 3 hours behind Greenwich (such as the eastern coast of the United States), local noon would occur at 10:00 AM. The navigator would measure the altitude of the Sun at this time, and then use a table or formula to calculate the ship's latitude and longitude based on this measurement and the current date.
Time 10:00 in Greenwich, England (10 AM)
Assuming that the ship is located in a time zone that is 2 hours ahead of Greenwich (such as Greece or Turkey), local noon would occur at 12:00 PM. The navigator would measure the altitude of the Sun at this time, and then use a table or formula to calculate the ship's latitude and longitude based on this measurement and the current date.
Midnight (24:00) or 12:00 AM
At midnight, the Sun is not visible and therefore celestial navigation cannot be used to determine the ship's location. However, other methods such as dead reckoning or GPS may still be used to estimate the ship's position.
Noon (12:00) or 12:00 PM
Assuming that the ship is located in a time zone that is the same as Greenwich (such as the United Kingdom), local noon would occur at 12:00 PM. The navigator would measure the altitude of the Sun at this time, and then use a table or formula to calculate the ship's latitude and longitude based on this measurement and the current date.
