Both Model A and Model B (same gravity)

Which system has the greater gravitational attraction between the two objects (if any)?

Same gravitational attraction fro System A and System B

Which of the following processes usually takes the longest amount of time?

An ocean basin forms between two land masses.

A storm system to move across the country

Water vapor condenses on the outside of a can

If we compare the temperature and pressure of Earth's mantle to the core, what differences can we expect as we move downward into Earth?

What two processes would cause the height of a Mountain to DECREASE ?

volcanic eruptions and landslides

tectonic collisions and earthquakes

Which of these factors does NOT influence climate?

distance from large body of water

Cutting down large forests (deforestation) can result in:

less plants to absorb carbon dioxide, a greenhouse gas

What do greenhouse gases do?

absorb Earth's outgoing radiation

reflect Earth's incoming infrared radiation

magnify ultraviolet radiation in the atmosphere

block the Sun's infrared radiation

Which of the following is the best conclusion that can be made from this graph?

atmospheric carbon dioxide levels have increased steadily since 1960

atmospheric carbon dioxide levels have been decreasing since 1960

Hawaii has a lot of carbon dioxide

humans have been working hard to decrease carbon dioxide levels

8.ESS.1.01 Which of the following best explains why seasonal variations in temperature are more extreme at location X than at location Y?

The angle of incoming solar radiation varies more at location X than at location Y.

The gravitational force is less at location X than at location Y.

The rotation of Earth has less effect on location X than on location Y.

The ocean moderates the average temperature more at location X than at location Y.

8.ESS.1.02 An astronaut drops a hammer on the Moon, and a scientist drops an identical hammer on Earth. Both hammers are dropped from the same height. The hammer dropped on Earth falls to the ground faster than the hammer dropped on the Moon. Why does the hammer on Earth fall faster than the hammer on the Moon?

Gravitational attraction is stronger on Earth than on the Moon because Earth has a larger mass.

Earth has a stronger magnetic field than the Moon because Earth orbits the Sun.

Earth has a stronger magnetic field than the Moon because Earth has an iron core.

Gravitational attraction is stronger on Earth than on the Moon because Earth rotates on its axis.

8.ESS.2.01 Which of the following processes created the high mountains of the Himalayas?

the collision of tectonic plates

8.ESS.2.01 A science museum wants to demonstrate some processes of Earth’s tectonic plates. Wooden blocks will be used to represent the tectonic plates. Which of the following demonstrations would best show how Earth’s tectonic plates interact with the layer directly beneath the plates?

floating the blocks on a slowly moving pool of thick mud

gluing the blocks onto solid rock

burying the blocks in a bed of dry sand

sliding the blocks along the top of warm solid metal

8.ESS.2.05 Lake Ontario, one of the Great Lakes, usually receives heavy snowfall during the winter. Snow often falls after a cold air mass passes through the area. This air mass tends to be colder than the lake water. Which of the following best explains why snow falls over the lake after the air mass passes over it?

Snow falls from clouds that form when rising water vapor from the lake is cooled by the air mass and condenses.

The air mass pushes clouds over the lake, and snow falls from the clouds.

Snow falls when sinking air from the air mass is warmed by the lake water.

The air mass cools the surface of the lake, causing condensation to occur and snow to fall.

The map below shows the locations of two cities. City Y is near the coast, and city Z is near the middle of a continent. The cities have the same elevation. Based on the map, which of the following statements describes how the climates of the two cities are most likely different?

City Y has cooler summers than city Z.

City Y receives less rain than city Z.

City Y has colder winters than city Z.

City Y receives more sunlight than city Z.

Which of the following is most similar to the number of stars in a galaxy?

the number of galaxies in the universe

the number of layers that make up Earth

the number of stars in our solar system

the number of planets in our solar system

The paths of two air masses, X and Y, are shown in the diagram below. Air mass X is a cold air mass. Air mass Y is a warm air mass. When the air masses meet, winter storms may be produced. Which of the following most likely contributes to the formation of these storms?

Warm air mass Y moves over cold air mass X, and condensation occurs.

Cold air mass X moves over warm air mass Y, and evaporation occurs.

Cold air mass X mixes with warm air mass Y, and the overall temperature increases.

Warm air mass Y mixes with cold air mass X, and the overall temperature decreases.
