question 2 of 25 which of these factors best explains why liquid water exists on earth? a. weak salinity of earths oceans b. freezing temperatures at earths poles c. presence of living things on earth d. earths strong gravity

Answer

Brief Explanations:

Earth's strong gravity helps hold the atmosphere in place. The atmosphere in turn helps maintain a temperature range that allows water to exist in liquid form. Salinity of oceans is not the main factor for liquid - water existence. Freezing temperatures at poles are a result of distance from the Sun and do not explain overall liquid - water presence. The presence of living things is a consequence of liquid water, not a cause.

Answer:

D. Earth's strong gravity
