What is when all the continental plates were connected forming the last supercontinent
100
Name three types of faults.
What are convergent, divergent, and strike and slip?
100
What’s the difference between magma and lava?
Magma is melted rock under the earth's surface, lava is magma that reaches the earth's surface.
100
Give one example of how glaciers cause erosion.
Glaciers pick up rocks and scratch the surface, push sediments creating valleys and moraines.
100
Give an example of mechanical weathering?
Water sometimes gets into the tiny cracks in boulders. If that water freezes, it expands, opening the crack even more and eventually splitting the rock into pieces.
200
Name the layers of the Earth starting at the inner core.
What are inner core, outer core, mantle, crust?
200
What happens at a divergent plate boundary?
What is two tectonic plates are moving away from each other?
200
How are sedimentary rocks formed?
What is lots of pressure on sediments?
200
Give one example of how water causes erosion.
Water cuts through rocks forming canyons and valleys
200
Give and example of biological mechanical weathering.
What is a tree root growing in a crack forcing the crack to grow?
300
What evidence supports continental drift theory?
What are similar fossils found on different continents?
300
What happens at a strike-slip plate boundary?
What is when two plates slide past each other?
300
How are igneous rocks formed?
What is cooling of magma or lava?
300
Give one example of how wind causes erosion.
Picking up small sediments and moving them from one place to another.
300
What is an example of chemical weathering?
What is acid rain reacting with rock changing the chemical makeup of the rock?
400
What causes tectonic plates to move
What are convection currents in the earth's mantel?
400
What is a convergent plate boundary?
What is when two plates move towards each other?
400
How are metamorphic rocks formed?
Heat and pressure on rocks
400
What are some ways to slow down water erosion?
Building dams, big rocks, trees, planting native plants with deep roots.
400
What is an example of biological chemical weathering?
What is lichen growing on rocks and sucking minerals from the rocks changing the chemical make-up of the rock?
500
How fast are the tectonic plates moving?
What is 2-5 cm per year? (About as fast as fingernails grow)
500
What is the ring of fire?
What is a continuous ring of volcanoes and trenches around the pacific plate boundaries.
500
How are rocks and minerals different?
Minerals are pure substances, rocks are made out of more than one mineral
500
How has Michigan been impacted by erosion?
The lakes were formed by glaciers. Grand Rapids is in a valley formed by the grand river.
500
What are some geological features caused by weathering?
