During a science experiment, Mischelle and Derick observed that a balloon filled with warm air started to rise. What causes the warm air to rise?

• Warm air is more dense than cooler air.

• Warm air is less dense than cooler air.

• Warm air has less gravitational attraction than cooler air.

• Warm air has more gravitational attraction than cooler air.

During a science experiment, Mischelle and Doug observed what happens to air as it cools. What did they notice?

• It stays put because its density doesn’t change.

• It rises as its density increases.

• It sinks as its density increases.

• It explodes as its density decreases.

While at the beach, Greyson and Kate recorded temperatures on land and at sea. They discovered that each morning the ocean and land had a similar temperature. On a sunny day, the sun continues to warm both the ocean and land, but unequally. During the day, which direction will the wind MOST LIKELY blow?

• The wind will not blow.

• The wind will blow toward land.

• It will vary throughout the day.

• The wind will blow toward the ocean.

Zion and Maddox are observing the unequal heating of land and water by the sun’s rays during their science class. The pattern seen here creates a __________ current and also is responsible, in part, for __________ on Earth.

• convection; wind

• conduction; rain

• radiation; snow

• evaporation; humidity

During a geography class, David and Mischelle learned that if the Earth didn’t rotate, winds would travel either north or south due to differences in temperature and pressure. But since the Earth does rotate, the ________ deflects these winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

• Coriolis effect

• Greenhouse effect

• Ozone layer

• Magnetic field

While at the beach, Jace and Sarah recorded the temperatures on land at sea. They discovered that at night, the ocean air temperature was higher than the temperature over land. During the night, which direction will the wind MOST LIKELY blow?

• The wind does not blow at night.

• The wind will blow toward the land.

• The wind will blow toward the water.

• There is no way to tell which wind will blow.

Yaretzy and Mischelle are discussing why winds are generated. Which factor is directly responsible for the pressure differences in the atmosphere that cause winds?

• The day-night cycle on Earth.

• Uneven landforms on Earth’s surface.

• Rotational motion of Earth about its own axis.

• The uneven heating of Earth’s atmosphere by the sun.
