Geological Events
What is seafloor spreading ?
The movement of two plates sliding past each other.
What is a transform boundary?
Soil Horizons from bottom to the top
A seashell found on a mountaintop means
What is the mountain was once under water
Weathering is a ____________ process where erosion is a ___________ process.
slow; fast
When magma rises and cools this geological event occurs
What is a volcano?
What is a convergent boundary
This layer is composed of unweathered rock and support landscape development
What is Bedrock, Horizon R
the area was once dry land and then became an area of water
The formation of Soil in layers
What is a mid ocean ridge?
Plate interactions that result in Earthquakes
What are Convergent, Divergent and Transform boundaries
This layer is the uppermost layer that contains organic material, ontains decomposed leaves, plants, and animal remains, forming nutrient-rich humus
Horizon O- Organic Matter
Evidence that shows the continents were once connected
Swampy areas or forest areas would have more __________ that is found in soil
organic matter/material
What are earthquakes?
Plate boundaries that form volcanoes
Divergent and Convergent boundaries
This layer is the reddish color, more dense layer, Supports deeper plant roots and stores nutrients despite reduced biological activity
The explanation of the Glossopteris Plant being found in Africa and Antarctica, however they are separated by bodies of water.
What is the Continental Drift Theory
Providence Canyon was formed as a result of
weathering and erosion (human activity with bad farming techniques)
When an oceanic plate meets a continental plate, this geological event will happen
What is subduction
Transform boundary
This layer consist of organic material that is dark in color due to humus and has plant roots
Topsoil, Horizon A,
What is a model
The greatest amount of deposition will occur at what area of non straight river (outside the curve or the inside of the curve)
on the inside of the curve of the river
