why do geological activities such as earthquake, volcanism and mountain formation happen to be confined on certain places around the globe?​

Answers

Answer 1
Answer:

The geological activities mentioned are found in the meeting areas between the tectonic plates.

Volcanism is

  • A geological phenomenon in which molten rock erupts from the center of the Earth toward the surface through a volcano
  • It is located between two tectonic plates

An earthquake is

  • A geological phenomenon in which movements of the Earth's crust
  • Occurs by accumulated energy in the tectonic plates

Orogenesis is

  • A geological process in which mountains are formed. In this process, the Earth's crust fractures fold and modify as a result of the lateral force of the tectonic plates

These geological processes are originated from the dynamics of the tectonic plates that produce movements in the interior and exterior of the Earth.

Answer 2
Answer:

Answer:

i dont know it is correct or not. sorry if the answer is wrong

Explanation:

When Alfred Wegener first proposed the idea of continental drift (the precursor idea to plate tectonic theory), it didn’t quite explain the full story. While he correctly showed that Africa and South America fitted together, his model wasn’t able to explain the violent forces that occur around the Earth’s crust.

How do the tallest mountains of South Asia compare to the tallest U.S. Mountain?

Answers

Mount McKinley is the tallest US mountain and Mount Everest is the tallest southwest asian mountain. The tallest mountains in southwest asia are taller than the tallest mountains in the US

Final answer:

Mount Everest in South Asia is the tallest mountain in the world at 8,848 meters, significantly taller than the United States' tallest mountain, Denali, which is 6,194 meters high. Factors such as gravity and tectonic activity can influence the height mountains can reach.

Explanation:

The tallest mountain in South Asia, Mount Everest, is also the tallest mountain in the world, standing at approximately 8,848 meters above sea level. In contrast, the tallest mountain in the United States is Denali (also known as Mount McKinley), in Alaska, which stands about 6,194 meters above sea level. Therefore, Mount Everest in South Asia is significantly taller than Denali in the United States. It's important to note that various factors such as gravity and tectonic activity can contribute to the heights that mountains can reach. For instance, even though Mars has less surface gravity and unifying plates, its tallest mountain Olympus Mons is more than double the height of Mount Everest or any mountain on Earth for that matter.

A rapid change in ocean density with change in depth is the: 1. halocline.
2. thermocline.
3. barocline.
4. isocline.
5. pycnocline.

Answers

Answer:

5. pycnocline.

Explanation:

Pycnocline is the rapid change in density of ocean water with depth. With increase in depth, ocean water tends to be denser. The two major factors that determine density in ocean water are temperature and salinity(salt contents). The denser water become in the ocean the more likely it sinks easily . This is one major factor that drive Ocean currents, the process is called thermohaline circulation.

The increase in salinity of ocean water causes an increase in density . This is because the salt become tightly pack and filled the water to make it denser .  This simply means an increase in saline content of ocean water causes an increase in the density.

Another factor that affects density is temperature. Water at the surface possesses higher temperature due to direct contact with the sun. Usually, the higher the temperature the less dense ocean water becomes . This is why surface water is less dense. As water becomes warm the molecule disperse, this account for it lower density . Colder water are usually higher in density .

Generally, an increase in ocean depth causes considerable increase in density because of it colder temperature and increased salinity contents.

Which of the following is the shortest interval of geologic time?an eon
a period
an era

Answers

An eon is a geologically around tens of millions of years. A period is a million year included in an eon which is also made up of several eras. Therefore my answer is a period due to it being a subset of an era which is a subset of an eon.

The answer is Period. This is the shortest interval of geologic time.
