Convergent Boundary
Divergent Boundary
Transform Boundary
100
At which plate boundary can earthquakes occur?
All of them!
Divergent, Convergent, Transform
100
What is soil made of?
Minerals, organic matter, broken up rock
100
What are the 3 types of rocks?
Sedimentary, Metamorphic, Igneous
200
Which layer of the earth is liquid?
Outer Core
200
What landforms are formed at convergent boundaries?
mountain ranges, volcanic arcs, oceanic trenches, island arcs, and volcanoes
200
How do volcanic eruptions affect the biosphere?
Volcanic eruptions can kill living organisms
200
What are the 5 layers of soil?
O, A, E, B, C
200
What are sediments?
Weathered, broken down pieces of rock
300
What are the two types of crust and which is thinner?
Oceanic (thinner) crust and Continental (thicker) crust
300
Illustrate the movement of ALL THREE plate boundaries.
300
What are the THREE must abundant gases released during a volcanic eruption?
*Hint: Use the picture below!
Sulfur dioxide, carbon dioxide, water vapor
300
What is weathering?
the process of wearing or being worn by long exposure to the atmosphere
300
How do igneous rocks form?
From magma that has cooled to form a rock
400
Do temperature and pressure increase or decrease as we move deeper into the Earth's layers.
Temperature and pressure INCREASE as we move deeper towards the Earth's core.
400
Look at the image below. Where would you live in order to experience the LEAST amount of volcanic activity/earthquakes?
4
400
What are the 2 types of waves in an earthquake, and which one is faster?
P and S; P is faster
400
What process must occur to sediments in order for them to become sedimentary rocks? Choose ONE.
a. Compaction and cementation
b. Heat and pressure
a. Compaction and cementation
400
How can a sedimentary rock become a metamorphic rock?
Any rock can become a metamorphic rock if it is exposed to intense heat AND pressure
500
Explain the process of subduction. Mention in which layer of the Earth subduction occurs.
A process in which one edge of an oceanic plate is forced below the edge of another plate. Subduction occurs in the mantle.
500
This is a picture of the San Andreas fault, located in California. What type of plate boundary formed this fault?
Transform Boundary
500
Give 2 examples of how a volcanic eruption affects the ATMOSPHERE
1. Gases released
2. Ash blocks sunlight--> cools temperature
3. Ash blocks sunlight--> no photosynthesis
500
Which process is responsible for the formation or expansion of cracks and potholes in road surfaces during winter, and how does it affect Earth's systems?
A This damage is caused by erosion, which is due to mechanical weathering.
B. This damage is caused by frost wedging, which is due to mechanical weathering, leading to the expansion of cracks and potholes.
B. This damage is caused by frost wedging, which is due to mechanical weathering, leading to the expansion of cracks and potholes.

What is the difference between weathering and erosion?
Weathering is the process of breaking down rocks, while erosion is the process of moving the broken-down rock fragments away
