Geography plays a significant, fundamental role in shaping outcomes in human societies.

Among other geographical elements, borders have significant implications"they are not

only geographical figures, but also political creatures. Against previous theories that have

studied border effects along with institutional differences mostly about economic

implications, this thesis considers how sub-national borders with weak jurisdictions affect

cultural, political, and economic phenomena using data from South Korea. Unlike

international borders and intra-national borders in a federal state, this thesis suggests borders

in a unitary nation have less economic effects, but more cultural and political effects.  It will never be answered unambiguously what determines human society the most.

Needless to say, numerous elements will synthetically form a way for people to live.

However, it seems obvious that among other elements geography plays a significant,

fundamental role in shaping outcomes in human societies.

" It is natural that geographical

features provide the foundation of countries; where a nation is physically located influences

patterns of endogenous lifestyle and who are the neighbor countries for the nation is likely to

set up exogenous international relations (Gottmann 1951, 154).

# These circumstances imply

that geographical conditions have effects on countries’ history and culture. Not only for

countries but also for individuals, geography determines many aspects of people’s sense of

self; for instance, depending on the place where a person is born or grows up, he or she will

have a different cultural identity, different nationality, and different institutional services for

his or her lifetime.

This suggests that geography has shaped a wide variety of the many aspects of human

life over time and that outcomes affected by geography impact human behavior. In this sense

that geography and human beings mutually affect each other, borders appear to be worth

examining because they are not only physical, geographical figures, but also political However, not all borders have the same significance; some borders offer important

ramifications while others do not create distinguishing implications.

" Theoretically,

international boundaries between two or more countries appear to have greater substantial

effects on political, cultural, and economic outcomes than do boundaries within countries.

The fact that national boundaries are disjointed points to autonomous countries partitioning

jurisdictions enables them to have relatively large potential effects. On the other hand, subnational borders seem to be less influential because they are more purely administrative

boundaries. Nonetheless, intra-national borders would have bifurcated characteristics

depending on type of government!whether it is a unitary nation or a federal state!since

borders within federal states, like the United States, also function as fairly powerful

jurisdictional borderlines.

Thus, existing theories on border effects could be classified as follows:

What negative impact does deep-sea bottom trawling have on the oceans and how did Gjerde help regulate and fix the problem

Deep-sea bottom trawling has a negative impact on the ocean by damaging delicate seascapes like ocean corals.

What is the significance of deep-sea bottom?

Numerous characteristics on the deep sea floor add to the habitat's variety. Mid-oceanic ridges, hydrothermal vents, mud volcanoes, seamounts, canyons, and cold seeps are the prominent geological features.

The diversity of habitats is also influenced by large animal carcasses in the deep-sea area of the sea. Deep-sea bottom trawling harms sensitive seascapes like ocean corals, which has an adverse effect on the ocean.

Gjerde documents efforts to cooperate with governments to assist them grasp the situation in order to help regulate and resolve the issue.

Therefore, After that, in just three years, they were able to alter the way that fishermen approached deep-sea bottom trawling.

will california sink into the ocean? explain

Answers

It is possible for part of California to sink into the ocean, but not all of it. About 10 million years ago (in the Tertiary Period), much of California sank beneath the waves. Then about 5 million years ago (in the Quaternary Period), parts of southern California rose out of the sea and started becoming dry land again.

Today, some areas are rising up while others are sinking down because plate tectonics are making new mountains in various places across the state while other areas are being worn away by erosion, especially near the coast where weather patterns often include high winds and heavy rains coming off of an ocean that is constantly churning with storms both large and small. The steady rise in global sea levels due to climate change also poses a threat. In the long term, as the great tectonic plates of Earth's crust continue to move and change as they have for billions of years, it is possible that the entire state of California could once again be submerged beneath water.

In order for all of California to sink into the ocean, something would need to happen along a fault line deep under the ocean floor where part of California's land mass rests on top of a subducting plate. If this were to happen, either an earthquake or volcanic eruption would eventually cause part – but probably not all – of California to rise up out of the sea as a new island continent.

Answer:

No because California is standing on top of earth’s crust where it stands two plates.

Explanation:

In order to invoke the SAS similarity criterion, the angle between the proportional sides must be congruent in the two triangles. Here, that angle is the same angle (angle B) in both triangles, which is why the reflexive property is cited. It tells you ∠B ≅ ∠B.
