The gases around and above Earth make up Earth's
What is atmosphere
100
How do scientists explain the fact that some landforms that are far apart and separated by oceans appear to be related?
What is continental drift.
100
What magma comes up through Earth's surface and hardens it is called
What is lava.
100
A crack in the Earth's crust is called a
What is fault.
100
The process by which weathered rock moves from one place to another
What is erosion
200
A mountain is an example of a ___________ on Earth's surface.
What is landform.
200
Where are volcanoes most likely to erupt? Why do you think this is so?
What is Volcanoes are most likely to erupt along the boundaries of Earth's plates. The plates of Earth's crust move. When the plates move, some rocks can break away and fall into the mantle where magma is formed. This movement increases the likelihood that magma will build up land and have to be pushed out of the volcano through an eruption.
200
A stationary pool of magma that forms below Earth's crust is called a
What is hotspot.
200
The amount of energy released by an earthquake is called
What is magnitude
200
Give an example of an important factor in chemical weathering of rocks.
What is acid rain.
300
A person who studies the history and structure of the Earth is a
What is geologist
300
How are the Mercalli Scale and the Richter Scale similar? How are they different?
What is Both scales measure earthquakes or events related to earthquakes. The Richter Scale measures energy released by an earthquake (magnitude). The Mercalli Scale measures the damage of an earthquake.
300
Magma flows through an opening in Earth's crust called a
What is volcano.
300
The sudden movement of Earth's crust is an
What is earthquake.
300
Explain how erosion and deposition work together using waves.
What is Waves can wash the sand off of beaches. The waves pick up the sand, eroding away the land in that area. The currents in the water can carry the sand to a different area of the beach. When the waves hit this area, they deposit the sand, causing the land to be built up.
400
Give examples of features on the ocean floor:
What is abysmal plains, trenches, and rift valleys.
400
Describe a delta. Explain how this type of landform is created.
What is A delta is where a river meets the ocean and land is formed. A delta is formed when the running water of a river picks up soil and rocks and deposits them where the river meets the ocean.
400
What is a shield volcano?
What is they are build by thinner fluid lava that spreads over a large area.
400
What can occur as a result of an earthquake that erupts under the ocean?
What is a tsunami.
400
What can cause chemical weathering?
What is pollution.
500
Draw a model of the Earth that includes atmosphere, core, crust, hydrosphere, and mantle.
What is see board or textbook.
500
A group of scientists wants to protect a delta. What can they do to prevent erosion caused by running water?
What is To prevent erosion to deltas scientists can use dams to control the speed of flowing water. They can build levees to control water direction.
500
Give characteristics of volcanoes.
What is magma flows through it, has at least one vent, occurs most often near the edges of tectonic plates.
500
What happens during an earthquake.
What is Forces in Earth push and pull the rocks around the fault, causing them to slip. This slipping causes the surface of Earth to move.
500
What are the causes of erosion?
What is gravity, wind, and running water.
