Studying Earth's Layers
100
What occur mostly on or near the fault lines between Earth's plates?
Earthquakes
100
What are the rocks that form, when layers of materials settle on top of each other?
Sedimentary Rocks
100
What is the thinnest layer made of hard, rigid rock and soil?
The Crust
100
What is the destructive process where materials move away from one area?
Erosion
100
What is the machine scientists use to monitor earthquake activity?
Seismograph
200
What are 2 of the 3 ways plates can move in Earth's lithosphere?
Colliding, Sliding, or Spreading
200
What is the property scientists use to identify and unknown mineral?
Hardness, Luster, Streak Test, or Texture
200
What is the layer that is made of melted iron?
The Outer Core
200
What is the process where (ice wedging) ice melts into small cracks of rocks, refreezes, expands, and breaks the rock apart?
Mechanical Weathering
200
What is one way scientists use fossils to understand layers of the Earth?
Understand the deeper fossils are older.
300
Erosion is the taking away of material. Name 3 types of erosion.
Wind, Weathering, Waves
300
What are the rocks that contain particles, that have been squeezed and heated at high temperatures?
Metamorphic Rocks
300
What is the thickest layer that contains convection currents?
The Mantle
300
What is the process where material is moved or deposited to a new area?
Deposition
300
What type of rock are fossils found in?
Sedimentary Rock
400
What are the 2 processes that happen when a volcano erupts?
Destructive and Constructive
400
What are the rocks, that are formed, then melted, cooled, and hardens?
Igneous Rock
400
What is the hottest, solid layer containing iron?
The Inner Core
400
What is process where material is worn away due to acid rain or pollution?
Chemical Weathering
400
Why would scientists find younger fossils before older fossils?
Older fossils are buried deeper than younger fossils in sedimentary rock.
500
What is a large destructive wall of water that moves land, buildings, and is very destructive?
Tsunamis
500
What this process rocks take that transforms them from one type to another?
Rock Cycle
500
What are the layers that make up the Earth's lithosphere?
The Top Part of the Mantle and Crust
500
Organize the following into either slow or fast changes to Earth's surface. earthquakes, weathering, deposition, volcanoes, erosion, tsunamis
Fast earthquakes,tsunamis,volcanoes Slow erosion,deposition,weathering
500
What is one type of test scientists use to determine the hardness of a mineral?
Mohs Scale
