Async Earth Science Semester Exam review

Match the following variables with their roles in this sample investigation about beach erosion.

• Independent variable

• Amount of sand

• Controlled variable

• Amount of water

• Result of the experiment

• Angle of the slope of the table

• Dependent variable

• Amount of erosion

Aiden is conducting an experiment to study erosion. Choose two (2) observations from the experiment that would be considered quantitative.

• Each stream table is filled with exactly 50 pounds of fine-grained sand

• Xavier prepares three identical stream tables, labeled Table A, B, and C. Each stream table is filled with 10 pounds of gravel.

• As the slope increases, the rate of erosion will also increase.

• More sand is being transported to the bottom of the stream table

Match the atmospheric layers with their corresponding heights.

• Thermosphere

• the Earth's surface to up to 690 km high

• Troposphere

• the Earth's surface to 10,000 km high

• Exosphere

• the Earth's surface to up to 6-20 km high

• Mesosphere

• the Earth's surface to up to 85 km high

The density (thickness)/air pressure of the air (a)   as you increase in altitude.

• High

• Low

• Constant

• Variable

• It has one natural satellite, the moon.

• It is classified as a gas giant.

• Its proximity does not allow for life.

• It contains water in three different forms such as a solid (ice), a liquid, and a gas (water vapor).
