What is the main entry point for nutrients in the littoral zone in lakes? How does this affect the biomass of this zone? How does it affect species diversity?

Answers

Answer:

D

the littoral zone is close to the shore and is partially submerged with shallow water. It is the uppermost zone of the aquatic water body. It is the part of lakes, rivers, ponds and sea.

Explanation:

took the test

The main entry point for nutrients in the littoral zone in lakes is runoff from the surrounding land.

This runoff can carry a variety of nutrients, including nitrogen, phosphorus, and potassium. These nutrients are essential for plant growth, and they can lead to a significant increase in the biomass of the littoral zone. The increased biomass in the littoral zone can support a greater diversity of species.

This is because there are more food sources available, and there is more space for different species to live. However, the increased biomass can also lead to eutrophication, which is the excessive growth of algae. This can make the water cloudy and foul-smelling, and it can also deplete the oxygen levels in the water.

Is an asteroid balanced or unbalanced

Answers

Answer:

should be balanced

Explanation:

When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. When the forces acting on an object are unbalanced, they do not cancel out one another.

Work is power x distance so 25x4 gets you 100 joules for work, and power is work divided by time so you get 100/5 and get 20 watts for power. Hope that helped

Use your model to explain how one of these metamorphic rocks: gneiss, marble, or quartzite could become igneous or sedimentary rock and how that rock could become a third type of rock.


my model: I could add to my model if it is needed in the answer.

Answers

Answer:

If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks.

Explanation:

The freshly created metamorphic rock may ultimately melt and become molten if it is heated further (magma). A rock called an igneous rock is created when molten rock cools. Sedimentary or igneous rocks can develop into metamorphic rocks.

What are Igneous and Metamorphic rocks?

To alter shape is to undergo metamorphism. It refers to alterations in rocks (protoliths) in the solid state, as understood by geologists (i.e. not by melting the rock wholesale). Metamorphosis may be compared to cooking. Changes take occurred when ingredients are combined and put at a different temperature (or pressure).

The thermal energy that propels metamorphism comes from a variety of sources. It goes without saying that the contact zone will become quite hot when an igneous mass with a temperature of 1200 degrees C intrudes into an unprepared host rock. Contact metamorphism, a rock-baking process, results from this.

Due to the heat generated by volcanic activity along the mid-ocean ridges, hydrothermal metamorphism takes place there. Anywhere contact metamorphism takes place, intrusion of igneous rocks is the driving force. Both of these types undergo metamorphism at low pressures and high temperatures.

Therefore, igneous rock is created when molten rock cools. Sedimentary or igneous rocks can develop into metamorphic rocks.
