Earth's Layers
The most massive layer of the planet.
What is the mantle?
Subjected to heat and pressure.
What are metamorphic rocks?
Boundary where plates push together.
What is convergent?
The breaking down of rocks, soil, and minerals.
What is erosion?
Result in weather conditions like droughts, floods, and warmer winters.
What is El Nino?
The outermost layer of the planet.
What is the crust?
Fossil remains are found in certain rocks.
What are sedimentary rocks?
Boundary where plates slide past one another.
What is transform?
Wind and water that causes erosion.
What is weathering?
The saltiness of water.
What is salinity?
The very center of the earth.
What is the inner core?
Found beneath the lithosphere.
What is magma?
Theory that Earth's crust is broken into plates that float on the mantle.
What is Plate Tectonics Theory?
Allows hot lava, volcanic ash, and gasses to escape from a magma chamber beneath the earth.
What are volcanoes?
Nutrients from the ocean floor are brought to the surface.
What is upwelling?
The third layer of earth starting from the surface.
What is the outer core?
Formed by the cooling and solidification of molten earth material.
What are igneous rocks?
Boundary where plate action creates volcanoes.
What is divergent?
Happens when two blocks of the earth suddenly slip past one another.
What are earthquakes?
All the continents started as one.
What is Pangea?
The combination of the crust and upper mantle.
What is the lithosphere?
Igneous rocks are usually found here.
What are volcanoes?
Convergent boundary where a dense plate is forced beneath a less dense plate.
What is subduction?
The reason magnetite molecules in bands of rock point in opposite directions.
What is polarity?
Sea-floor mountain system formed by plate tectonics.
What is mid-ocean ridge?
