Why are nutrients and gases most evenly distributed in a lake in the winter?

Biology
1 answer:
kvv77 [185]2 years ago
3 0

When the temperature reaches 0˚C (32˚F), the top layer of the lake freezes and turns into ice. In solid form, water molecules are less dense and thus ice floats on the top of the lake.

This solid barrier prevents any wind-induced mixing as well as protects the relatively warm water underneath. Furthermore, light is also blocked so that photosynthesis is inhibited during this period. As the lake water is separated from the atmosphere, no direct oxygen diffusion occurs.

All these factors together causes a more even distribution of nutrients and gases in a lake in winter.

Small intestine, liver, bile and lipase.

Which is the first step that geologists must do to compare rock layers at distant locations? 1.find the absolute age of rocks at
VARVARA [1.3K]

Answer:

2.compare a layer at one location to layers at other locations

Explanation:

Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.

Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.
