What seasonal change refreshes the supply of nutrients throughout a lake?
Seasonal turnover, also known as lake mixing, is a process where cooler water sinks and replaces warmer water at the surface of a lake. This brings nutrients from the deeper layers to the surface, refreshing the supply of nutrients throughout the lake.
The rising of cold water from deeper layers to replace warmer surface water is called .?
upwelling
Is it true that older rocks are usually closer to earth's surface than more recent rock layers?
No. Think about it. Why do archaeologists usually have to dig down to find the remains of ancient civilizations? The same is true with sedimentary rock history.
How does warm water at the surface of a lake mix with deeper water?
Warm surface water and cooler deep water can mix through a process called convection. As warm water cools, it becomes denser and sinks, displacing deeper water and causing mixing. Wind and currents can also help in mixing water layers within a lake.
Process of warm surface water mixing with deep cooler water in a lake?
This process is called lake turnover. During the spring and fall, changes in temperature cause surface water to mix with deeper water layers. This helps distribute nutrients and oxygen throughout the lake, benefiting aquatic life.

What is The rising of cold water from deeper layers to replace warmer surface warmer surface water?
upwhelling
Which terms describes the rising of cold water from deeper layers to replace warmer surface water?
Upwelling.
The rising of cold water from deeper layers to replace warmer surface water is called .?
upwelling
What is the rising of cold water from deeper layers to replace warmer surface water called?
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.

Is layers of rock near the surface are the oldest rocks?
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.
What happens to the temperature in earths layers?
As you go deeper and deeper the layers will start to get hotter and thicker.

Which term describes the rising of cold water from deeper layers to replace warmer surface water?
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.
Why water in pond feels warmer at its surface but cooler from below in summer?
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.
