What layer of the earth do we live on?
crust
What does the word geoscience mean?
Earth science
What do we call the giant supercontinent that scientist use to believe existed?
Pangea
What is the process that takes rocks that have been changed or broken apart and moves them?
Erosion
What are the three main types of rocks?
Sedimentary, metamorphic, and igneous
List the layers of the earth from outermost to inner most
crust, mantle, outer core, and inner core
What are the three types of plate boundaries?
Transform boundary, convergent boundary, and divergent boundary

Rocks being made smooth by tumbling across a streambed is an example of ________ .
Weathering
How are sedimentary rocks formed?
Small pieces of rock that are compacted and stuck together
What layer of the earth is a solid ball of metal?
inner core
What kind of plate boundary is represented when two plates move away from each other?
Divergent boundary
In our studies, where did we discover most volcanoes occur?
The Ring of Fire (a path along the pacific ocean)
Flood waters moving soil from one location to another is an example of ______ .
Erosion
How are metamorphic rocks formed?
When rocks are under intense heat and pressure
The lithosphere is made up of two main layers of the Earth. Which two layers?
crust and upper mantle
When two plates push together this is called a convergent boundary. What type of landforms can occur when plates move this way?
A convergent boundary can cause trenches and mountains.
List two pieces of evidence that support the theory of Pangea.
1. Like fossils on different continents 2. Shapes of continents that look like parts of a puzzle that “fit” together 3. Same glacial patterns on different continents 4. Like landforms on different continents
Glaciers dropping rock and sand to form terminal moraines is an example of ______ .
Deposition
How are igneous rocks formed?
Magma deep in the earth cools OR lava cools outside of the earth
Why is the outer core a liquid?
There is not enough pressure for it to be a solid
Which type of plate boundary can cause earthquakes and tsunamis when they slide against one another?
A transform boundary
What scientific concept could Wegener use to justify his scientific claim about Pangea?
The movement of tectonic plates
