Earth Station Review
Station1: Earth’s Interior
Directions: Read the descriptions of Earth’s Layers and study the model at your group.
Answer the following questions.
1. Label the earth’s interior layers by looking at the model.
A. Inner Core
B. Outer Core
C. Mantle
D. Asthenosphere
E. Crust
F. Lithosphere
2. What is the lithosphere and where is it located? The rigid outer part of the earth,
consisting of the crust and upper mantle.
3. What is the asthenosphere and where is it located? The upper layer of the earth's
mantle, below the lithosphere, in which there is relatively low resistance to plastic
flow and convection is thought to occur.
4. What are convection currents and where are they located? Convection currents are
movements caused by temperature changes in liquid or gas. Located in the
mantle.
Station 2: Earth’s Plates
Directions: Study the map at your group and label the plates using the labels from your
zip lock bag.
1. What are the names of the six major tectonic plates? North American Plate, South
American Plate, Indo-Australian Plate, African Plate, Eurasian Plate, and Pacific
Plate
2. Label the plates on the map.
3. What is the Ring of Fire and what plate is it located on? The Ring of Fire is an area in
the basin of the Pacific Ocean where a large number of earthquakes and
volcanic eruptions occur. This occurs on the Pacific Plate.
Station 3: Plate Boundaries
Directions: Match the correct boundary with the correct definition and picture. Use the
arrows to show which way the plates move.
1. Write the definition of each boundary.
a. Convergent Boundary: Places where plates collide together.
b. Divergent Boundary: Places where plates move away from each other.
c. Transform Boundary: Places where plates slide past each other.
d. Subduction Zone: Places where plates slide underneath each other.
2. Draw arrows showing which way each boundary moves.
a. Convergent Boundary:
b. Divergent Boundary:
c. Transform Boundary:
d. Subduction Zone:
3. What is formed from each boundary?
a. Convergent Boundary: Mountains
b. Divergent Boundary: Mid-Ocean Ridge, Rift Valley
c. Transform Boundary: Earthquakes
d. Subduction Zone: Volcanoes, Trench
Station 4: Define the following terms.
1. Mid-ocean ridge: undersea mountain range that forms where two parts of Earth’s crust
our pushing up.
2. Ocean basin: anywhere on Earth that is covered by seawater.
3. Trench: a deep narrow ditch
Station 5: Define the following terms:
4. Plate Tectonics: a scientific theory that describes the large-scale motion of Earth's
lithosphere.
5. Rift Valley: a linear-shaped lowland between several highlands or mountain ranges
6. Volcano: a rupture on the crust of a planetary-mass object, such as Earth, that allows
hot lava, volcanic ash, and gases to escape from a magma chamber below the surface
Station 6: Density of Earth’s Layers
1. Where is the Earth the densest? The inner core.
2. Are objects denser on the bottom or the top of our Earth layers? Bottom
