Earth Science
100
Processes at or near Earth’s surface that cause rocks and minerals to break down.
What is weathering?
100
2 types of crust
What are oceanic and continental?
100
weathered igneous rock
What is sand?
100
three types of rocks
What are igneous, sedimentary and metamorphic?
100
the study of rocks and minerals
What is geology?
200
Processes that break a rock or mineral into smaller pieces without altering its composition.
What is mechanical weathering?
200
rigid outer layer (crust)
What is the lithosphere?
200
A dead organism found in a sedimentary rock.
What is a fossil?
200
Formed from molten material including volcanic lava, ash, or bombs as well as magma below Earth’s surface
What is igneous?
200
A theory that explains how rocks move.
What is plate tectonics?
300
Processes that change the chemical composition of rocks and minerals.
What is chemical weathering?
300
solid rock that flows slowly (like hot asphalt)
What is the athenosphere?
300
The process by which water, ice, wind or gravity moves fragments of rock and soil.
What is erosion?
300
Rocks that are changed by intense heat and pressure while inside Earth’s surface.
What is metamorphic?
300
Geographers of the 1500's were the first to notice that some continents seemed to fit together into puzzle pieces which formed this massive continent.
What is pangea?
400
Water that enters a rock and then freezes, over time breaking up the rock.
What is frost wedging?
400
Earth’s crust is broken into about 19 pieces.
What are the tectonic plates?
400
The process of blowing soil away.
What is wind erosion?
400
Made of layers that have been pressed or cemented together.
What is sedimentary?
400
Scientists found common mountains, fossils, and coal on each continent.
What is the evidence that supports the plate tectonic theory?
500
Three forces that cause weathering over time.
What is wind, water, and gravity?
500
the water layer and the air layer that mix with the lithosphere.
What are the hydrosphere and atmosphere?
500
A mound formed on land by the wind's deposition of eroded sand.
What is a sand dune?
500
A never-ending process of rocks forming, weathering, and changing into other rocks.
What is the rock cycle?
500
two plates collide, pushing up layers of rock.
What is a mountain?
