Rocks
Made of different minerals and chemical compositions.
What is the 1st layer (mechanical) of the earth.
Lithosphere
What is the first layer of the atmosphere?
Traposphere
What is continental drift?
That earth's continents move over geologic time.
Mechanical VS Chemical Weathering?
Mechanical breaks down rocks into small little pieces without changing their composition, while chemical weathering breaks down rocks and forms new minerals.
How are igneous rocks formed?
Molten rock heating then cooling.
What is the 2nd layer (mechanical) of Earth.
Asthenosphere
What is the 2nd layer of the atmosphere?
Stratosphere
Who came up with the concept of continental drift?
Alfred Wegner
What is abrasion?
Process of erosion that happens when material is transported and wears away at surface over time.
What are the 2 types of igneous rocks?
extrusive and intrusive
What is the 3rd layer of the earth ( mechanical)?
Mesosphere
What is the 3rd layer of the atmosphere?
Mesosphere
What is plate tectonics?
A scientific theory (lithosphere comprises tectonic plates which have been moving over the past million yrs)
What causes rain?
Air rises into upper atmosphere and cools.
What are the 2 types of metamorphic rocks.
Foliated and non-foliated
What is the 4th layer of the earth (mechanical)?
Outer core.
What is the 4th layer of the atmosphere?
Thermosphere
What causes tectonic plates?
Convection Currents.
What produces water vapor?
Evaporation of boiling liquid or sublimation of ice.
What are the 3 types of sedimentary rocks?
Chemical, clastic, and organic.
What is the 5th layer of the earth (mechanical)?
Inner core.
What is the 5th layer of the atmosphere?
Exosphere
What is Pangaea?
The idea that once all continents were together as one form of land and because of continental drift have now separated.
Rain, snow, sleet, and hail.
