Jojo wants to conserve energy. She wants to find out the lowest water temperature and the shortest amount of time that is needed to wash her clothes and get them clean. She washes one shirt in hot, one in warm , and one in cold water. The shirts are identical and have identical stains. She uses the same detergent and washes the shirts for the same amount of time.

Why is it important for Sherice to wash the shirts for the same length of time?

• to find out both the lowest temperature and the shortest length of time that is needed.

• If she doesn't then she cannot find the lowest water temperature that is needed

• She can find out the shortest length of time that is needed.

• It is NOT important, because she is not testing the length of time that is needed.

Which of the following would allow a scientist to replicate the experiment of another scientist?

• a controlled experiment

• background research

• a detailed scientific journal

• results that confirm the hypothesis

In 1922, a mathematician created a way to forecast weather using math equations. Unfortunately, this method would have required 64,000 people all working on separate equations for many hours to produce a single forecast. Today’s computer models can update a forecast in the time it takes to enter new data.

How does this example demonstrate why technology is an important part of science?

• It reduces the need for math in science.

• It reduces the need for people to become scientists.

• It can improve the speed at which information is processed.

• It reduces the number of calculations that scientists must make to predict weather.

Tianna wants to investigate the percentage of hurricanes that make landfall in the United States. She also wants to know their names, when they made landfall, and the damage they caused.

Which type of scientific investigation should she perform?

• Perform a controlled experiment on the variables that affect hurricane strengthening.

• Interview a local meteorologist about hurricanes that have made landfall in the United States

• Obtain and analyze historical data from the National Weather Service website.

• Watch the Weather Channel’s live report of a hurricane making landfall.

Heat transfer drives a variety of processes in Earth’s systems. 

 

 

Which of the following is an example of heat transfer through radiation in Earth's systems? 

 

• Heat rises through vents in the ocean floor.

• Warm air replaces cooler air in the atmosphere.

• Beach sand is heated by the Sun.

• Hot gases are given off during volcanic eruptions.

The water cycle describes how water moves through Earth’s systems. A simple model of the water cycle is shown in the diagram.

What process would be the best label for arrow 1 in the diagram?

• Condensation

• Evaporation

• Precipitation

• Transpiration

The jet stream is a global pattern of atmospheric movement that influences the weather. In general, one can expect clear skies with high-pressure and cloudy skies with low pressure. The jet stream is represented by the arrows in the weather map.

Which city is presently experiencing clear skies, but will see cloudy skies soon

• Los Angeles

• Omaha

• Cleveland

• Atlanta

Mrs. Whitworth tells the students to make sure they bring their jackets to school tomorrow. She knows that there will be a front of cold air moving in soon because of the change in low-pressure system caused by jet streams.

Which of the following best explains how jet streams influence local weather patterns?

• They cause movements of ocean water in a continuous flow.

• They can blow from north to south and form along the borders of masses of hot and cold air.

• Their path fluctuates to the north or south depending on the location of hot and cold air masses.

• They create a force (known as the pressure gradient force) that causes air to move

Which of the following is an example of an interaction between Earth’s hydrosphere and geosphere?

• Plants absorb water needed for photosynthesis through their roots.

• A river carries and deposits sediment downstream to form a delta.

• Volcanic eruptions release ash and gas into the air.

• Air masses cool and condense as they rise in altitude over the ocean.

Which of the following most accurately describes an interaction as illustrated in the diagram?

• Plants release carbon dioxide into the air.

• Oxygen in the air is taken in by animals on the ground.

• Heavy rainfall causes a landslide on the side of a mountain.

• Water vapor in the air cools and forms clouds.
