According to the diagram, the formation of pyroclastic material occurs when?
(pic above)
Answers
Pyroclastic flows form in various ways. A common cause is when the column of lava, ash, and gases expelled from a volcano during an eruption loses its upward momentum and falls back to the ground. Another cause is when volcanic material expelled during an eruption immediately begins moving down the sides of the volcano. Pyroclastic flows can also form when a lava dome or lava flow becomes too steep and collapses.
Pyroclastic flows often occur in two parts. Along the ground, lava and pieces of rock flow downhill. Above this, a thick cloud of ash forms over the fast-moving flow. Such a flow can transform the landscape drastically in a short period of time. Not only does it destroy living material in its path, it often leaves behind a deep layer of solidified lava and thick ash.
Pyroclastic flows may result in flooding as streams are blocked or rerouted by the flow. Floods may also occur when the flow of hot material melts snow and ice, swelling rivers and streams beyond their banks. A mudflow containing volcanic material, called a lahar, may also form when the rock of the pyroclastic flow mixes with water to become a quickly moving slurry.

what happens to the shape of a substance in a Liquid phase ?

Answer:
If on a flat surface, it will widen and flow freely until friction stops it.
Explanation:
Answer:
In the liquid phase the molecular forces are weaker than in a solid. A liquid will take the shape of its container with a free surface in a gravitational field. In microgravity, a liquid forms a ball inside a free surface. Regardless of gravity, a liquid has a fixed volume.

How is solar radiation distributed during the night?
Answers
Answer:
During the night, radiation is distributed through clouds and water vapor in the atmosphere.
Explanation:
The night allows the earth not to receive direct solar radiation, because the night represents the moment when a certain part of the earth is in the opposite position to the sun. However, solar radiation is still important at this point to keep the earth warm. In this case, clouds and atmospheric water vapor are responsible for distributing solar radiation during the night. This is because they absorb this radiation throughout the day and reintroduce this energy to the earth at night.

Answer:
I would guess the physical land feature that matches both of these in the list of "Pre-Columbian Inca Empire" would be valleys. If it is asking for more you can add rich soil quality and good climate to the physical quality of the setting.
Explanation:
The definition of a feature is a quality or a special attraction. If farmers developed terraced agriculture to produce the food they need a certain physical land feature to make this happen. And if builders constructed roads to connect the territories of the empire they needed a specific land feature as well. So my guess out of all the physical land features the one that fits best here is valleys. The soil in valleys is good for farming. Not as many people live in the mountains. Mountains can be rugged and steep. Food is harder to grow in the mountains. Plains would be too dry and empires cannot be built on just flat plains.

What is humus and why is it important for soil
Answers
Answer:
humus the dead remains of plants and animals.lt is important for the soil because it helps the plants grow better as it contains minerals for the soil
Answer:
Humus is dark, organic material that forms in soil when plant and animal matter decays. Humus contains many useful nutrients for healthy soil. One of the most important is nitrogen. Nitrogen is a key nutrient for most plants.
Explanation:
. Nutrient supply
Organic matter contains nutrients that are released after the breakdown by soil organisms. Studies indicate that two to three pounds of sulfur, 4.5 to 6.6 pounds of phosphorus oxide and 20 to 30 pounds of the macro-element nitrogen are released by every percent of organic matter found in the soil.
2. Water holding capacity
For the soil to be healthy, it must have enough moisture. It must also have a good water retention capacity according to different crop requirements. Organic matter provides the soil with the capacity to retain water. It acts like a sponge and it has the capacity to hold water, approximately 90 percent of its own weight. Water being held by the organic matter is readily available to the crops when needed.
3. Cause soil aggregation
Soil aggregation is formed by clumping together of soil particles. Organic matter has the capability of causing the soil particles to clump together due to its adhesive properties to form soil aggregates. Soil aggregation improves soil structure which is also a property of healthy soil.
4. Improves soil structure
Soil structure is the aggregation of soil particles in different patterns. A good soil structure is an indicator of healthy soil. One of the most significant factors affecting soil structure is the presence or absence of humus.

Answers
Answer: Weathering
Explanation:
Weathering is a process of break down of parent rock into sediments by agents like water, wind, or any other agent.
The lithification can be defined as the process of formation of the soil into the sedimentary rock. In this process the parent rocks first get weathered and loose soil particles form sediments. Then compaction of sediments, cementation and recrystallization of minerals occurs in the soil.

Answers
Answer: Yes, there is a need to limit the utilization of resources on planet earth.
Explanation:
Non-renewable resources are those resources which cannot be replenished once used. Their concentration of planet is decreasing. For example, fossil fuels like coal, petrol, and natural gas. Special mining sites are required to explored for their extraction. These are not available in all regions of the world and must be used judiciously as they may not be available in future.
