Movement of continents over time changed the location of land and sea, this affects the global patterns. Volcanic activity aerosoles and ash are let into the atmosphere and stay there for years and make the temperature lower. Solar energy lets out sunspots which are dark, cooler regions on the surface of the sun.

I can give you one:
One of the theories (in which i mostly believe in) is the one when every period of time, the climate changes. Now, we are in the warmth period, but after this period, there will be a cooler climate, and keeps repeating every while (think about the ice age)

tester [92]

Answer:

The greatest gravitational potential energy is at apogee. The greatest kinetic energy is at perigee. Total Energy is constant.

Explanation:

The gravitational potential energy is at its greatest when the satellite is farthest from the earth, this point is called the apogee. And at this point the kinetic energy will be at its minimum.

The kinetic energy is greatest when the satellite is closest to the earth, this point is the perigee. And at this point the gravitational potential energy will be at a minimum level.

the total energy is the sum of the gravitational potential energy and the kinetic energy.As the satellite orbits the earth, the kinetic energy and the gravitational potential energymay be interchanged but the total energy will remain unchanged.
