Rocks
Formed when Magma cools
Igneous Rock
transforms rock into new substance.
chemical weathering
sheets of rock, peel like an onion
exfoliation
Grow from ground due to dripping of dissolved calcite
stalagmites
Pulls higher locations to lower locations, primary force for all mass movements
Gravity
Formed when Sediments are compacted and cemented together
sedimentary
What are things that affect weathering?
temperature and moisture
What makes rust?
Chemical weathering oxidation and reaction of acids
stalactite and stalagmite grow together
column
Melts faster than new snow fall, forming U shaped valley
Receding Glacier
Formed when heat and pressure change igneous or sedimentary rock
Metamorphic
What is frost weathering?
Rocks small holes fill with water, freezes and wedging forces apart
What are cave explorers?
spelunkers
decayed organic material in earth
Humus
Pulling out rocks eventually forming valleys
Plucking
forces shaped Earth in past are same forces today and at same rate
Uniformitarianism
What is frost heaving?
water freezes underneath rock, pushing it out of the ground
What are speleothems
formations in caves
What is Pedologists
scientists who study soil
What are glaciers?
ice formations erode rocksand sediment changing landscape
breaks rocks into smaller pieces.
mechanical weathering
What is abrasion
Rocks rub against each other, develop round smooth edges.
what are stalactites?
hang from ceiling and look like stone icicles
What is erosion?
weathered material moving from one location to another
What is deflation?
wind blows, picks up loose sediment, and carries away
