Answer:
C. Earth's solid surface layer sits on a moving, semiliquid layer.
Explanation:
Earth is highly tectonically active because the solid layer of the earth sits on a moving, semi-liquid layer.
The earth's crust is broken into slabs. Together with part of the upper mantle, they form a layer called the lithosphere. These solid lithospheric bodies are called tectonic plates.
- Under the plates is a semi-molten layer under great temperature.
- As the molten layer moves, it carries the lithosphere on top of it.
- This causes the movement of the plates in different directions.
- The semi-liquid layer is called the asthenosphere
This is the reason why the earth is tectonically active.
Answer:
1.mesosphere is a coldest atmospheric layer surrounfing the earth
2.it become cloud enough to freeze water vapour
3.the ice cloud are blue white are caled noctilucent

- The secondary environment consists of consumers that are also divided into primary and secondary that is wolves and Man.
- The decomposers are the last in the food chain that acts of dead and decaying reasons and converts the nutrient energy into the soil that is take up again by plants.
