What is the thinnest layer of the earth?
The crust
100
What was the name of our supercontinent?
Pangea
100
What type of rock is this?
Sedimentary rock
100
What are the broken down smaller pieces of rocks called?
Sediments
100
What is a palentologist?
A person who studies fossils
200
What layer of the earth is the thickest?
The Mantle
200
What forms when plates move towards each other?
Convergent Boundries
200
These are all examples of what kind of rock?
Igneous
200
On Earth's surface, what causes rocks to change?
Weathering and Erosion
200
The deeper the fossil is underground, the ______ it is.
older
300
What layer is made up of nickel and iron that is puddy like? (not fully liquid but not fully solid)
The outer core
300
What type of boundary causes underwater bridges?
Divergent
300
I need heat and pressure to be created
I am deep below the surface
2 of my nicknames are slate and marbleWhat kind of rock am I?
Metamorphic rock
300
How does a metamorphic rock change into an igneous rock?
When the metaorphic rock melts and turns into magma and the magma cools, igneous rock is formed.
300
Fossils are often found in what type of rocks?
Sedimentary rocks
400
What is the hottest layer of the earth?
The inner core
400
Where do earthquakes often form?
Transform boundaries.
400
What type of rocks forms only deep underground?
Metamorphic
400
How does an igneous rock turn into a sedimentary rock?
Weathering and erosion cause the igneous rock to break down into sediments. The sediments then go through compaction and cementation. This causes a sedimentary rock to form.

What do fossils help us understand about the earth?
They help us understand how Earth's landscape and climate have changed over time. (It doesn't have to be verbatim, just along those lines.)
500
What are each of the layers of the Earth made of?
Crust- rock and soil
Mantle- molten rock and magma
Outer core- iron and nickel
Inner core- solid nickel and iron (hottest layer)
500
How many inches do our plate boundaries move each year?
1-4 inches
500
Explain how each rock is formed.
Igneous rocks - formed when hot, melted rock (lava) cools
Sedimentary Rocks- formed when layers of dirt and sediment build up over time, then the layers are pressed together
Metamorphic rocks- formed due to heat and pressure beneath the Earth's surface
500
What do I need to do to go from a Metamorphic rock to sediments?
Weathering and erosion.

If you found a fossilized body of a fish on top of a mountain, what does that tell you about that area?
All reasonable answers.
