What is weathering?
1. When wind or water carry away bits of broken rock and soil
2. When rocks are broken by wind, water, tree roots, temperature changes, acid rain, or by falling.
3. When bits of rock or soil, called sediments, are dropped down in a new place by wind or water.
What's erosion?
1. When bits of rock or soil, called sediments, are dropped down in a new place by wind or water.
2. When rocks are broken by wind, water, tree roots, temperature changes, acid rain, or by falling.
3. When wind or water carry away bits of broken rock and soil
What's deposition?
1. When wind or water carry away bits of broken rock and soil
2. When rocks are broken by wind, water, tree roots, temperature changes, acid rain, or by falling.
3. When bits of rock or soil, called sediments, are dropped down in a new place by wind or water.
What is sedimentary rock?
1. Rock that is formed when layers of sediment pile up over thousands or millions of years.
2. Rock formed when rocks melt because of extreme heat and then cool off again.
3. Rocks changed by heat and pressure under the Earth's surface.
What is metamorphic rock?
1. Rock formed when rocks melt because of extreme heat and then cool off again.
2. Rock that is formed when layers of sediment pile up over thousands or millions of years.
3. Rocks changed by heat and pressure under the Earth's surface.
What is igneous rock?
1. Rocks changed by heat and pressure under the Earth's surface.
2. Rock formed when rocks melt because of extreme heat and then cool off again.
3. Rock that is formed when layers of sediment pile up over thousands or millions of years.
What are tectonic plates?
1. A kind of rock
2. Huge pieces of the Earth's crust that float on top of the mantle and fit together like a puzzle.
3. A kind of mineral used to make different kinds of rock
What are the layers of the Earth, starting from the center and working your way up to the surface?
1. core, mantle, magma, crust
2. inner core, mantle, crust
3. inner core, outer core, mantle, crust
4. tomato sauce, mozzarella cheeze, pepperoni, crust.
What's the difference between magma and lava?
1. Magma is extremely hot, melted rock. Lava is cooled off.
2. Magma is hot, melted rock under the Earth's crust. Lava is hot, melted rock that is pouring out of a volcano onto the surface of the Earth.
3. Magma is hotter than lava.
4. Lava is underground; magma is coming out of a volcano.
What causes earthquakes and volcanoes?
1. Lava causes earthquakes and volcanoes
2. The shaking of the Earth
3. The movement of tectonic plates bumping against or past each other
4. Fire-breathing dragons fighting each other.
What are rocks made of?
1. Rocks are made up of different kinds of minerals.
2. Rocks are made of soil.
3. Rocks are made up different kinds of rock
What is sand made of?
1. Sand is made of a powdery substance formed from the Earth
2. Dried salt that washes up from the ocean and dries out.
3. Tiny bits of broken rocks, minerals, or seashells
What is soil made of?
1. Dirt and mud
2. Sand
3. Tiny bits of rocks, minerals, and organic material (decayed plants and animals) .
What is the Mohs scale?
1. It's a list of different rocks
2. It's a list of different minerals and how hard they are.
3. It's a list of minerals and what they look like
How are fold mountains created?
1. Earthquakes break up the Earth.
2. Tectonics plates move toward each other and crumple upwards and they crunch together.
3. Fold mountains are created by volcanic rock piling up over time
What caused the Grand Canyon to form?
1. Deposition
2. An earthquake
3. Weathering and erosion
