Unit 3 Review

During El Niño, the warmer ocean waters of the hydrosphere evaporate faster, leading to more moisture in the atmosphere. This leads to weather occurrences that affect both the geosphere and the biosphere. Students have been asked to explain how El Niño affects the following systems in the United States: geosphere, hydrosphere, atmosphere, and biosphere. Choose the correct order of events below. Place them in the order that they happen.

• 1. Clouds carry small water particles over land. 2.Warmer water results in more water evaporating into the air. 3. Clouds forced even higher by mountains produce rain. 4. As the water vapor rises in the air, it cools and condenses to form clouds.

• 1. Warmer water results in more water evaporating into the air. 2. As the water vapor rises in the air, it cools and condenses to form clouds. 3. Clouds carry small water particles over land. 4. Clouds forced even higher by mountains produce rain.

A teacher pours water into a glass beaker. She heats the beaker and the liquid begins to boil. Soon it appears as if there is no liquid left in the beaker. Stephanie claims that the water disappeared. Tony claims that the water did not disappear. Which student’s claim is accurate? Explain.

• a. Stephanie; the water disappeared because we can no longer see it.

• b. Stephanie; the water disappeared because the beaker weighs less.

• c. Tony; the water didn’t disappear, it just changed forms.

• d. Tony; the water didn’t disappear, the beaker absorbed it.

Factories often release harmful substances into the atmosphere. These substances pollute the air. An engineer wants to reduce all of the air pollution coming from a factory. First, she focuses on pollution from one harmful substance, ash. She places different materials over a model of a chimney to stop particles of ash from getting into the air. She measures the amount of pollution that each material catches and makes a graph of the results. What should be the engineer’s next step?

• a. Find and fix any problems with Material 4.

• b. Make and sell Material 1 to nearby factories.

• c. Test Materials 1 and 2 on a real factory chimney.

• d. Retest the materials with a different type of factory pollution.

The graph below shows how much of Earth’s water is fresh water, salt water, and other kinds of water. Which claim is supported by the data in the graph?

• a. Most of Earth’s water is in the ocean.

• b. Most of Earth’s water is in lakes, rivers, and streams.

• c. Most of Earth’s fresh water is in glaciers or underground.

• d. Earth’s water is split evenly between fresh water and salt water.

Humans and many other living things require fresh water to survive. There is more rain in many areas during an El Niño year, but not all of this water adds to Earth’s fresh water supply. Select all of the statements below that describe paths that water can take that add to our supply of freshwater. (3 Answers)

• a. Water flows through streams and rivers into a local lake or pond.

• b. Water falls as snow and becomes part of a glacier on a mountaintop.

• c. River water flows downstream through streams and rivers into the ocean.

• d. Water absorbed by the ground becomes groundwater that supplies wells.

• e. Water falls directly back into the ocean and is circulated by ocean currents.

What happens when waves move across the surface of deep water?

• The water moves forward.

• The water moves backwards.

• The water moves up and down.

• The water does not move.

What is amplitude?

• The distance from the middle point of a wave to the wavelength

• The distance from one crest to the next crest

• The distance from one trough to the next trough

• The distance between the middle point of a wave and a crest or trough

What is wavelength?

• The distance from the middle point of a wave to a trough.

• The distance from the middle point of a wave to a crest.

• The distance from one crest to the next crest or one trough to the next trough.

• The distance from a crest to a trough.

What does it mean if waves have short wavelengths?

• The distance from one trough to the next is small.

• The distance from one trough to the next is large.

• The distance from the middle point of a wave to a trough is small.

• The distance from one crest to the next trough is large.
