Answer:
The carbon cycle plays a key role in regulating Earth's global temperature and climate by controlling the amount of carbon dioxide in the atmosphere. The greenhouse effect itself is a naturally occurring phenomenon that makes Earth warm enough for life to exist.
As the burning of fossil fuels and landscape alterations, such as deforestation and industrial agriculture, mobilize fossil carbon into the atmosphere, the earth's carbon cycle is pushed out of balance and climate changes. Human generated climate change is an enormous perturbation in the global carbon cycle.

Answer:
A. 40 cm
Explanation:
For a curved mirror, the focal length is twice the radius of curvature of the mirror. In formula:
where
f is the focal length
R is the radius of curvature
The concave mirror in this problem has a radius of curvature of
R = 20 cm
so, its focal length is
The more energy a particle has the more it will move faster . If you take some cold solid material and add energy to it (heat it up) the particles in it will rattle around more. Usually at some point they will rattle so much that they break up the regular solid pattern and start sliding around as a liquid.
