Convection, Pressure System, and Weather Quiz

How does a stationary front form?

• A stationary front forms when a cold air mass pushes out a warmer air mass.

• A stationary front forms when a warm air mass pushes out a cooler air mass.

• A stationary front forms when a cold and warm air front combine, and one front overtakes the other.

• A stationary front forms when a cold and warm front collide, but neither front is strong enough to overtake the other.

A weather map with isobars is shown. What is the most likely reason for including isobars in the map?

• Isobars help to predict future air pressures.

• Isobars help to identify patterns in air pressures.

• Isobars help to show areas experiencing a stationary front.

• Isobars help to identify areas likely to experience a warm front.

How are air pressure and altitude related?

• As altitude increases, air pressure decreases.

• As altitude increases, air pressure increases.

• As altitude increases, air pressure remains the same.

• As altitude increases, air pressure increases and then decreases.

What is the main cause of the cold in the coldest region(s) and the heat in the hottest region(s) of Earth?

• the amount of precipitation in the region

• the amount of direct sunlight received in the region

• the presence or absence of ice in the region

• the temperature of the rising or falling air in the region

The diagram below shows how sunlight interacts with Earth's surface.

Sunlight plays a role in warming ocean waters. The Earth is curved, so sunlight reaches Earth at different angles. Select the two statements below that BEST describe the effects shown in the diagram.

• Earth experiences uneven heating across its surface.

• Earth experiences even heating across its surface.

• Earth is warmest in areas where sunlight reaches its surface at 90°.

• Earth is warmest where sunlight reaches its surface at 45°.

• Earth experiences the same temperatures at both incoming sunlight angles of 45° and 90°.
