Description: There are several factors that impact climate on Earth. Different areas on Earth have different climates depending on factors such as their latitude and surrounding terrain. Maps of annual average precipitation illustrate these variations in climate. Continentality also affects climate based on the ability to change temperatures on land versus in the oceans and also the imbalance of land mass between the northern and southern hemispheres. Seasonality is a dominant factor in climate. It is controlled by the amount of solar insolation received at the Earth's surface, which varies in time due to the tilt of the Earth's rotation axis.
