True or False. Weathering causes stones to become smooth.
True.
100
True or False. Sand in a river delta is an example of deposition.
True.
100
Which layer of Earth does an earthquake begin?
the crust
100
How many main layers is Earth made up of?
4
100
Define erosion.
process of moving weathered rock from one place to another.
200
What landform is the result of deposition?
Delta
200
What event would most likely contribute to gradual underground cave formation?
an avalanche
200
Certain land features form at plate boundaries. Which land feature is likely to form most quickly?
volcano
200
Earth is made up of many layers. Which layer is responsible for the movement of Earth's plates?
the mantle
200
Define weathering.
process of rock breaking apart
300
Ice splitting rock would be what process?
Weathering.
300
What is the difference between weathering and erosion?
Erosion moves rocks without breaking them down.
300
Which type of plate movement forms mountains?
plates push against each other
300
Earth's plates move in many different ways. Think about the location of Earth's continents today. Describe what has happened over the millions and millions of years.
The motion of Earth's plates has carried the continents to different locations, slowly over time.
300
What would be the best way for a scientist to study the effects of plate movements?
visit an active volcano
400
The crust, mantle, outer core and inner core are all __________ of Earth.
Layers
400
Many rocks will contain cracks & be right on top or next to a plant. What will happen to the rock and plant over time?
The plant will grow and the crack will expand.
400
Ice and water are two agents that can be involved in the process of weathering. Explain how freezing and thawing can cause weathering.
Many rocks contain tiny cracks. When it rains, these cracks fill with water. If the temperature drops, the water in the cracks turns to ice. As ice is formed, it expands. Over time, the repeated processes of freezing and thawing will cause these cracks to grow. Eventually, the rocks will break apart.
400
How do water and gravity work together to change Earth's surface?
Gravity pulls water downhill, causing weathering, which produces sediment, and erosion, which moves the sediment.
400
Which process begins in Earth's mantle below Earth's crust?
a volcanic eruption
500
What would most likely happen if two plates move in different directions and slide against each other?
earthquake
500
What is one way to stop the process of erosion?
Plant Grass or Plants in the specific area needed to stop the erosion.
500
Explain why water erosion is most likely to have an effect on landforms in a hilly region that has a warm and rainy climate.
Water erosion requires water and an incline. Other environments, such as deserts and arctic areas, lack flowing water and tend to be flat.
500
Suppose an earthquake occurred under an ocean. Explain why such an event would generally be considered less destructive than an earthquake on exposed land.
Generally, earthquakes beneath the ocean would not directly affect built structures that are on land.
500
True or False. Earth's crust is made up of plates that rest on the mantle. A typical plate is 250 miles wide.
False-A typical plate is 2,500 miles wide.
