it gets colder because there is less warmth from the sun
No, global warming is a rise in the temperature of the earth. Global warming is causing climate change.
It doesn't - the moon's proximity to Earth has no bearing on Earth's temperature - the Sun does that.
The surface temperature of the Earth is affected by many different factors. Although Earth's orbit alters the distance between the sun and Earth, the change in surface temperature is minimal compared to other factors. As evidence of this, consider the surface temperature at the poles, well below freezing at all times. Now compare this with the temperature in the tropics, where the temperature can be 60C higher than the poles. Consider also the change in temperature between night and day. Once again, there is a significant change in temperature with no significant change in distance from the sun. Factors such as cloud, wind and many other meteorological factors change the surface temperature more than the distance from the sun. However, we are able to say that the energy that reaches the Earth from the sun is reduced when Earth is further away from the sun. The amount of energy is inversely proportional to the square of the distance between sun and Earth.
The temperature increases with increasing depth within Earth's crust.

The temperature increases with increasing depth within Earth's crust.
Because - the further you are away from the Earth's surface - the lower the temperature is.
When the Earth orbits the sun different sides of the earth face the sun.Therefore changing the temperature.
that it regulates he temperature
In general, the temperature decreases towards the surface.
