The map below shows the ages of the top layers of soil in an area where scientists are searching for fossils.
Scientists located a fossil in the top layers of soil in region W, which formed up to 66 million years ago (mya). However, the scientists were unable to locate that same type of fossil in the other regions of the map. Which statement best explains why the scientists were unable to locate this fossil type outside of region W?
C. The fossil is from an animal that went extinct 50 mya.
A geologist drew the map below.
What major landform is shown on the map?
C. mountain range
The cracks in this rock were made by ice. Water went into small cracks and froze. When the ice formed it pushed the rock apart. This happened many times, and each time the cracks got bigger.
What is this an example of?
B. weathering
Steve fixes one end of a rope to a wall and moves the other end of the rope up and down to create a wave, as shown below.
If Steve wants to increase the wavelength of the wave, what should he do?
Wind turbines are used to transform energy from wind into electrical energy. This happens when a wind turbine spins after wind blows on it. The energy of motion from the spinning wind turbine is then transformed into electrical energy. A picture of wind turbines is shown below.
How can this source of energy best be described?
A. It is a clean, renewable source of energy that works best in places with open fields.
Scientists began to dig in a new location where there are many layers of artifacts and fossils. Today, archaeologists reached the lowest layer and discovered fossils of fish bones and plants there.
What might have been in this area many years ago before all of the other layers of fossils came into being?
B. water
The image below shows where minor earthquakes happened during a 24-hour period. The larger dots represent stronger earthquakes.
What does the map show about earthquakes and their locations?
A. Most earthquakes happen close to where a continent meets an ocean.
Which of these would be best for investigating how moving waves cause changes to land?
C. observing the shape of the land in different places along the ocean shore
The power went out at Rachel's house, so she lit a candle.
What two forms of energy does the burning candle release?
C. heat and light
Several objects are shown below.
Which object was designed to convert electrical energy into sound?
B. speaker
Scientists found an index fossil in layer Z that was about 400 million years old. They determined that in that area, a new layer of earth was deposited every 50 million years.
If a fossil was found in layer W, how old was the fossil?
D. about 100 million years old
Ocean trenches are the deepest parts of the ocean floor. They are shown as blue lines on the map below. The area where frequent volcanic activity takes place around the Pacific Ocean is known as the Ring of Fire. This area is highlighted on the map.

What does the map show about the locations of the trenches and volcanoes?
A. Trenches and volcanoes occur around the same locations.
Jasmine made a stream table by putting some sand on a cookie sheet. She tilted the sheet and ran water down it.
Which of these could Jasmine learn from the stream table?
C. how erosion caused by running water shapes land
A waterwheel is a device that spins as water flows across it, as shown in the picture below.
When a waterwheel is connected to a generator, the kinetic energy of the waterwheel is converted into electric energy. What change to the waterwheel would help it make more electricity?
A. increasing the speed of the water and the wheel
Landforms have changed during Earth's history. Which of these can be used to explain how the landforms in an area have changed over time?
C. the patterns in rocks and the types of fossils in rock layers
The image below shows a land formation in the southwestern United States.
What process most likely caused this land formation?
A. a moving river cutting through rock over time
The image below shows a map of certain mountain ranges and earthquakes in North and South America.
What does the map show about where earthquakes occur?
D. Earthquakes generally occur around mountain ranges.
Which of these is an example of wind erosion?
B. Strong air currents break off small pieces of boulders and carry those pieces away over very long periods of time.
Marcie takes a picture of a canyon. She notices layers in the rock of the canyon walls and a river running deep within the canyon. Her picture is shown below.
Marcie claims the canyon formed because the river cut away at the rock over a long period of time. What evidence in her picture best supports her claim?
D. the layers of rock on each side of the river are similar
The maps below show information about volcanoes and earthquakes in a certain region of Earth.
Modified images courtesy of NASA
Which statement best describes volcanoes and earthquakes?
A. Volcanoes and earthquakes are located in bands on the boundaries between oceans and continents.
The picture below is a model of many rock layers.
What does the model show?
B. Large rock layers can crack and move over time
A satellite image and a topographic map of the island of Hawaii are shown below.
A farmer wants to buy a large, flat piece of land on the island to plant crops. What location best fits this description?
C. Y
Sonia's teacher shows her class an example of weathering and erosion in the diagram below.
How could Sonia’s teacher lead her class in an investigation that models this type of weathering and erosion?
D. Put a rock with small cracks in it in water to soak, put the rock in the freezer, and observe it later.
The picture below shows several layers of rock.
Marine fossils are found in layer 3. Land-dwelling animal fossils are found in layer 1. What does the location of the fossils indicate about the land in this area?
B. The area was at one time underneath the ocean.
Some of the electricity used in homes come from coal-burning power plants. Cars use gasoline as fuel. Gasoline comes from oil that went through processing plants.
Where do coal and oil come from?
D. natural resources that come from the Earth
