Earth's Layers
Layers of the Earth from least dense to most dense
Boundary where two tectonic plates collide and form mountains, volcanoes, and deep trenches
What is convergent boundary?
The 5 characteristics of a mineral
What is naturally occurring, solid, inorganic, crystalline structure, and the same chemical composition throughout?
What is topsoil?
Resources that are available in limited amounts and can be exhausted by human activities and can't be renewed fast enough
What are nonrenewable resources?
The solid, outer part of the Earth containing the upper mantle and crust, composed mainly of rock
What is the lithosphere?
Boundary where tectonic plates move away from one other and form rift valleys and mid-oceanic ridges
What is divergent boundary?
Rocks formed from a volcano
What are igneous rocks?
Soil horizon that contains the most rocks
What is Horizon R- Bedrock?
A resource in which there is an endless supply because it can be replenished, such as the sun, wind, water, and geothermal heat.
What are renewable resources?
The hottest layer of the earth that is solid from pressure
What is the inner core?
Boundary where tectonic plates slide past each other forming strong earthquakes
What is transform boundary?
Rocks formed from pressure or heat
What are metamorphic rocks?
The processes that break down and move rocks
What is weathering, erosion, and deposition?
Rocks that contain fossils
What are sedimentary rocks?
The only liquid layer of the Earth
What is the outer core?
Created from heat within the asthenosphere that cause the tectonic plates to move several centimeters per year
What are convection currents?
Rocks formed from pieces of a river over millions of years
What are sedimentary rocks?
What is a diamond?
The location where most earthquakes form
What is near a coastline and/or at plate boundaries?
The two types of crust
What are continental and oceanic?
The location where plates collide and one is thrust beneath another and powerful earthquakes, tsunamis, volcanic eruptions, and landslides occur
What is a subduction zone?
Ways a mineral can be identified
What is color, streak, luster, hardness, shape, and cleavage?
Two questions:
This was the supercontinent.
This evidence supports the theory of plate tectonics.
What is Pangea?
What is plate have slowly drifted apart, and evidence is that continents used to fit together like puzzle pieces?
Why the sea floor is not spreading
What is because new crust is made at a mid ocean ridge, and in another location subduction destroys older crust?
