7th Grade Science Comprehensive Test

Front

What is the relationship between carbon dioxide levels and Earth's surface temperatures?

Back

Higher carbon dioxide levels mean more heat is retained in Earth's atmosphere.

Front

What causes Earth to experience seasons?

Back

Earth experiences seasons due to its tilt as it revolves around the sun.

Front

What happens to air pressure when warm air rises?

Back

As warm air rises, it creates an area of lower pressure, and cooler air flows in as wind.

Front

What do the black arrows on a wind pattern diagram typically represent?

Back

Trade winds.

Front

Which type of air mass brings warm and dry weather?

Back

Continental Tropical (cT).

Front

What is the definition of 'air pressure'?

Back

Air pressure is the force exerted onto a surface by the weight of the air above that surface in the atmosphere.

Front

How does temperature affect air pressure?

Back

Warmer air is less dense and rises, creating lower pressure, while cooler air is denser and sinks, creating higher pressure.

Front

What are the main types of winds based on pressure differences?

Back

Winds flow from areas of high pressure to areas of low pressure.

Front

What is the significance of the Earth's tilt in relation to climate?

Back

The tilt of the Earth affects the angle of sunlight received, leading to seasonal changes in climate.

Front

What are the characteristics of Maritime Tropical (mT) air masses?

Back

Maritime Tropical air masses are warm and humid, typically bringing precipitation.
