GEOLOGY

Detailed explanation-1: -Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.

Detailed explanation-2: -The geothermal gradient is the amount that the Earth’s temperature increases with depth. It indicates heat owing from the Earth’s warm interior to its surface. On average, the temperature increases by about 25°C for every kilometer of depth.

Detailed explanation-3: -The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere .

Detailed explanation-4: -As you go deeper into the ocean, the temperature decreases and the pressure increases.

Detailed explanation-5: -As greenhouse gases trap more energy from the sun, the oceans are absorbing more heat, resulting in an increase in sea surface temperatures and rising sea level. Changes in ocean temperatures and currents brought about by climate change will lead to alterations in climate patterns around the world.
