Upwelling.
The term that describes the rising of cold water from deeper layers to replace warmer surface water is called upwelling. Upwelling occurs when winds push surface water away from the coastline, allowing cold, nutrient-rich water to rise and replace it.

The process is called upwelling. It occurs when winds push surface water away from the coast, which allows deeper, colder water to rise and replace the displaced water. Upwelling brings nutrients from the ocean floor to the surface, supporting marine life.
This process is called upwelling. Upwelling occurs when winds push surface water away, allowing cold, nutrient-rich water from deeper levels to rise up to the surface. This phenomenon is important for supporting marine ecosystems by bringing nutrients to the surface and supporting the growth of phytoplankton.
No, typically the layers of rock near the surface are the youngest rocks, as they have been deposited more recently. The deeper layers are usually older as they were deposited earlier in time. This is known as the principle of superposition in geology.
As you go deeper and deeper the layers will start to get hotter and thicker.
During summer, the sun heats the surface of the pond more quickly than the deeper layers due to direct sunlight exposure. This results in the surface water feeling warmer. Conversely, the deeper layers of the pond remain cooler as they are not in direct contact with the sun's heat, creating a temperature difference between the surface and the bottom.
sounds like erosionA2. This describes freeze-thaw spalling of rocks.
The relationship between soil temperature and depth is that as you go deeper into the soil, the temperature tends to remain more stable and less affected by changes in the surface temperature. This is because the deeper layers of soil are insulated by the layers above them, which helps to regulate the temperature.
Generally, yes, deeper water tends to be colder due to a phenomenon called thermal stratification. In many bodies of water, the surface layers are warmed by sunlight, while deeper layers remain insulated from the sun's heat. However, this can vary depending on factors such as location, season, and water currents. In some cases, deeper waters can be warmer, particularly in geothermal areas or certain oceanic conditions.
New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition.
