Earth
Earths lithosphere is believed to be broken up in pieces.
What are plates?
The upward moving mass of a rock forms a mountain when one plate is moving up while the other is stationary or moving down
What is a fault block mountain?
The preserved remains of a once living organism.
What is a fossil?
made from sediments which are sand, minerals and other materials that are primarily laid down by water
What is sedimentary rock?
The decayed remains of once living creatures.
What is humus?
A noticeable change in the density at the bottom edge of the Earth's crust.
What is the Moho?
2 moving rock masses push against one another and the crust buckles into an up and down rolling pattern
What are folded mountains?
The process of wearing or grinding something down by wind, water, or other natural agents.
What is erosion?
Made from molten rock, or magma; from volcanic eruptions.
What is igneous rock?
The boundary between 2 plates.
What is a fault?
The study of the earth's physical structure, its history, the processes acting on it and the rocks of which it is composed.
What is geology?
There is a crack in the crust but it does not go all the way to the surface. The magma cannot escape and instead builds up, pushing the crust up along with it. It is similar to a volcanic mountain, but rounder in shape.
What is a domed mountain?
Other material comes in and fills the mold left by an eroded or decomposed shell.
What is a cast?
Rock that has changed its form often due to extreme heat or pressure.
What is metamorphic rock?
Formed by rivers carrying along large amounts of sediments as they flow and then slowing down when the river path forms abend or empties into the ocean.
What are alluvial plains.
Normally flows like thick molasses.
What is plastic rock?
The idea that the main reason for Earth's geological features is due to catastrophes, like the flood.
What is catastrophism?
When organic material chemically changes into rock.
What is petrification?
Inorganic crystalline substance found naturally in the Earth.
What are minerals?
When the minerals in a rock chemically react with are or water, changing their composition.
What is chemical weathering?
The first layer of the earth; relatively thin.
What is the crust?
The present is the key to the past; like a river is responsible for slowly carving out an entire canyon.
What is uniformitarianism?
When large rocks are broken into small rocks from physical forces such as ice, temperature changes and abrasion of sand or running water.
What is physical weathering?
Has some sharp, geometric shapes. Has flat surfaces or faces and well defined edges.
What is crystalline?
Water that is suggested to have been underground interconnected chambers, about 1/2 of the earth's water.
What is supercritical water?
