Types of Rocks
Sediments can come from which types of rocks?
All 3! Sedimentary, Igneous, Metamorphic
Rock fragments, clay, and sand are products of what process?
Weathering
The thinnest layer that is made of solid rock
Crust
The type of plate movement that slides by one another
Transform
Which type of rock commonly has fossils?
Sedimentary, like Limestone
What must cool and harden for an igneous rock to form?
Lava or Magma
The process of sediments moving is called...
Erosion
A liquid layer of molten metal
Outer core
The type of plates that move away from each other
Divergent
In many layers of sedimentary rock, where would the oldest fossils be?
At the bottom
Name an example of an igneous rock.
Pumice, Obsidian, Basalt
The process of sediments being deposited to a new location is called...
Deposition
Which layer is the thickest? It consists of magma.
Mantle
The type of plates that come together. Sometimes one plate will slide under the other or both will rise up.
Convergent
Rain keeps washing away soil on a playground. What is a possible solution to stop this run off?

What two things must occur for a metamorphic rock to be formed?
Heat and Pressure
Expanding neighborhoods, building factories, and constructing highways all have what kind of effect on the Earth?
Negative impact
This layer is the hottest and under the most pressure
Inner core
Another name for a transform boundary is..
Sliding
Why are the Blue Ridge Mountains smoother than the Rocky Mountains?
They have been exposed to more weathering.
How is sedimentary rock formed?
Sediments compact and cement together
Recycling and planting have what kind of impact on the Earth?
Positive impact
The inner and outer core are both made of which metals? How are these two layers different?
Iron and nickel
The outer core is melted(liquid)- The inner core is solid.
Convergent plates create....
