Types of Rocks
A rock formed from sediments being compacted together.
Sedimentary
True
What layer of the earth do we live on?
Crust
Pangea
What are the three R's? (Think of the three arrows)
Reduce, reuse, recycle.
An igneous or sedimentary rock that has gone through intense heat and pressure.
Metamorphic
What happens to a sedimentary rock that undergoes heat and pressure?
Turns into a metamorphic rock.
Which layer is the thickest layer?
Mantle
What happens at a divergent boundary?
Plates move apart. Mid-ocean ridges or volcanoes form.
What's one way you can help with climate change?
Recycle, reuse, ride your bike, walk, compost, etc.
A rock formed from hardened and cooled lava.
Igneous
What happens if a metamorphic rock melts?
Turns into magma...starts the cycle all over again.
What is the mantle made up of?
Pockets of magma.
What happens at a transform boundary?
Plates slide past each other. Causes earthquakes.
How do factories effect climate change?
They pollute the air by releasing steam and gases into the atmosphere.
What type of rock are you most likely to find fossils in?
Sedimentary
What do weathering and erosion do to rocks?
Break down rocks and carry the sediments away.
Why is the inner core solid if it's the hottest?
Because of the pressure from all the other layers.
What happens at a convergent boundaries?
Plates collide and form upward: mountains. Trenches form underwater.
What is climate change?
Changes in weather over long periods of time.
What are rocks made up of?
Minerals
What is deposition?
What is the inner core and outer core made up of?
Iron and nickel. Outer: liquid. Inner: solid.
Why do the tectonic plates move?
The magma in the mantle is moving; therefore, the crust on top of the mantle is moving.
What is the greenhouse effect?
Traps the heat from the sun in the atmosphere to warm the earth.
