Based on the weather map above, which statement is true based on the weather map?
alisha [4.7K]

Answer:

A warm front is moving towards South Carolina bringing rainy conditions

Explanation:

From this weather map, we can see that South Carolina will soon be under the influence of a warm front. The warm front is moving towards this state, and it is coming from southeastern direction, thus it has been formed over warm waters. Because it has been formed over warm waters, this front is warm and very moist which will result in lot of rainfall once it comes upon a natural barrier to cause condensation, and the Appalachian Mountains will do just that, thus South Carolina will receive a lot of rainfall.

Which of the following two events occur to create a sea breeze? Select all that apply. Warm air rises on the ocean and moves tow
Xelga [282]

Answer:

Warm air rises on land and moves toward the ocean to cool

Cool air moves from the ocean to be warmed by the land

Explanation:

The land heats up faster than the oceans during the day. This is because water has a high heat capacity and takes more energy to raise its temperatures by one degree (even in comparison to land). Therefore land heats up the air above it faster than the oceans. The air mass over land rises due to drop in density. The cooler and denser air mass above the oceans moves towards land to replace the rising warm air. This creates a cool breeze felt on land during the day as the cool air rushes in.
