Layers of Earth
The hottest layer of the Earth's core.
What is the inner core?
The large landmass containing all continents before continental drift moved them apart.
What is the supercontinent named Pangaea?
This type of boundary creates slickensides.
What is a transform fault boundary?
The breaking down of rocks into sediments.
What is weathering?
The Horizon has topsoil and most leaching.
Liquid iron that surrounds the inner core and creates Earth's magnetic fields.
What is the outer core?
This scientist created the theory of continental drift.
Who is Harry Hess?
The type of boundary that creates mid-ocean ridges, rift valleys, and volcanoes.
What is a divergent boundary?
This type of weathering is done by movement through wind, water, ice, or gravity.
What is erosion?
The Horizon where you find solid rock called bedrock.
What is Horizon D?
The coldest layer of Earth's core. Also where the coolest people are.
What is the crust?
New sea floor is created in this process at divergent boundaries.
What is sea-floor spreading?
The type of boundary that creates mountains, deep ocean trenches and volcanoes.
What is a convergent boundary?
When sediments settle in order from largest to smallest. This also happens when rivers empty into oceans.
What is graded bedding?
The dark layer where living organisms and humus can be found.
What is Horizon O?
Large pieces of Earth's crust that move over the asthenosphere.
What are lithospheric/tectonic plates?
This type of lava or magma is thicker and stickier.
What is silica rich lava or magma?
These two processes are how sedimentary rocks are formed.
What are compaction and cementation?
Bacteria, water, and air are components of this resource.
What is soil?
This type of material settles closer to Earth's core.
What is more dense, less buoyant, cooler material?
Because of convection within the mantle, cooler, denser tectonic plates will do this at convergent boundaries.
What is subduction?
The three categories for volcanic activity (whether just erupted, not about to erupt, or no longer able to erupt).
Igneous rocks that form inside the earth, and igneous rocks that form outside the earth.
What are intrusive and extrusive rocks?
What is humus?
