Layers of the Earth
The rocky, outer layer of the Earth we live on. It is divided into two categories, Oceanic and Continental.
What is the crust?
A force that builds land or adds to the surface of the earth.
what is a constructive force?
The Earth's crust is made up of 7 large plates and many smaller ones. These have moved throughout Earth's history. Used to explain the formation of mountains, earthquakes, volcanoes, and ocean basins.
What is the theory of plate tectonics?
The Intense sudden shaking of Earth’s surface caused by release of built up pressure when tectonic plates slip past each other along a fault.
What is an earthquake?
This type of rock is formed by a volcano or the solidification of molten rock.
What is igneous rock?
The innermost layer of the planet. Super hot and under so much pressure it is actually a solid. Made up of nickel and iron.
Earthquakes, which crack the earth's crust and breaks structures, are this kind of force.
What is a destructive force?
This is the type of plate boundary where the plates pull away from each other, creating new land from magma turning to igneous rocks in ocean basins.
What is a divergent plate boundary?
An opening or vent in the Earth’s crust that allows magma, ash, and gases to escape from below the surface. Sometimes makes mountains. They form at tectonic plate boundaries
What is a volcano?
What is a metamorphic rock?
Layer of the Earth between the crust and the outer core. It is the thickest layer made up of hot magnesium, iron, and silicate rocks. It can behave plastically despite being a solid.
What is the mantle?
A slow destructive process that occurs when wind, water, or ice picks up soil and rock and carries them away.
What is erosion?
This is the type of plate boundary where they move towards one another, usually with one plate slipping under another, often forming mountains or volcanoes.
What is a convergent plate boundary?
the location directly above the hypocenter, on the Earth’s surface where earthquakes start.
What is an epicenter?
Type of rock formed by sediments being deposited by air or water and building up in layers.
What is sedimentary?
A different category/name for the crust and upper mantle because of the way it behaves. It rides on top of the flowing asthenosphere. It makes up the landforms and land we as humans have access to.
What is the lithosphere
A slow constructive process that drops sediments from erosion in a new place and can change a landscape.
What is deposition?
This is the type of plate boundary where they slide past each other, sometimes getting stuck and shifting suddenly due to pressure and can cause earthquakes.
What is a transform plate boundary?
Hot, molten rock below the earth's surface. It is called lava when it erupts from a volcano.
What is magma?
A dark nutrient rich substance found in soil that is made up of decomposed plant and animal matter.
What is humus?
Heat driven cycle of movement. Warmer, less dense material rises while cooler, denser material sinks, creating a continuous, circulating flow that transfers energy. It happens in the mantle and is essential to tectonic plate movement.
What are convection currents?
This natural disaster is considered a constructive and deconstructive force.
What is a landslide/flood/volcanic eruption?
This is the name of the super continent when all of the plates were connected 250 million years ago.
What is Pangaea?
This word describes a volcano that is currently erupting or will erupt soon. It is not dormant, it is ______
What is active?
The 5 layers of soil.
What is the organic layer, topsoil, subsoil, parent material, and bedrock?
