Plate Tectonics
A scientifically supported idea.
What is a theory?
Weathering and erosion create these rock particles.
What is sediment?
This machine records the arrival of seismic waves following an earthquake.
What is a seismograph?
What is a volcano?
This process breaks down rocks.
What is weathering?
The scientifically supported idea the Earth's crust and upper mantle are broken into pieces (tectonic plates).
What is The Theory of Plate Tectonics?
What type of rock is formed from volcanoes?
What is igneous rock?
This is a break in the Earth's crust or mantle; most occur at plate boundaries.
What is a fault?
The three types of volcanoes are?
Cone, shield, stratovolcano
What are the two types of weathering?
What is physical and chemical?
What are the two types of plates?
oceanic and continental
What type of rock is formed when existing rocks are transformed by heat, pressure, or chemical reactions?
What is metamorphic rock?
These two land formations can be formed by earthquakes.
What are valleys and mountains?
Volcanoes are generally classified by this type of activity.
What is how often they erupt?
This is the process of moving rocks, soil and organic matter from one place to the other.
What is erosion?
Plates that move away from each other make up what type of boundary?
What is a divergent boundary?
This is a type of rock that forms when broken down pieces of other rocks settle and accumulate in a body of water
What is sedimentary rock?
This is the devastating waves caused by an earthquake.
What is a tsunami?
These volcanoes have gentle slopes and a fluid lava that generates slow eruptions.
What are shield volcanoes?
The depositing of rock particles and organic matter that has been eroded is called?
What is deposition?
Interactions of plates at boundaries can produce great changes on land and under the ocean. What land forms can be made due to movement at the plate boundaries?
What are volcanoes, mountains, trenches, and valleys?
What are weathering, erosion, heat, pressure, compaction and cementation?
This is the measure of an earthquakes strength and intensity.
What is magnitude?
These volcanoes no longer erupt.
What are extinct volcanoes?
What materials make up soil?
What is rock particles, minerals, decayed organic material, water, air?
