Unit 2 Exam Review Flashcards
Convergent boundary
When 2 plates push together and collide, creating deep ridges
Divergent boundary
When 2 plates pull away from eachother, creating ridges
Transform boundary
When plates slide past eachother sideways, causing earthquakes
Tectonic plate
A massive slab of solid rock floating on the earths mantle
Weathering
The process of something being worn down because of long exposure to the atmosphere
Erosion
The gradual destruction or diminution of something
Lava
Hot molten or semifluid rock erupted from a volcano
Magma
Hot fluid or semifluid material below or within the earths crust
Deposition
The laying down of sediment carried by wind, water, and ice
Climate change
The long-term changes in global tempatures in the atmosphere
Coniferous
Forests that consist of mostly conifers, which are trees that grow needles and pinecones
Deciduous
A tree or a shrub anually shedding its leaves
Sedimentary
A rock that is formed from sediments deposited by water or air
Igneous
A rock formed from cooled magma or lava
Metamorphic
A rock formed from a rock that has undergone transformation by heat, pressure, and certain fluids
Humus
The organic component of soil, by the decomposition of leaves and other plants
Climate graph
Displays yearly tempature and precipiation statistics for a certain location
Moraine
A mass of rocks and sediment carried down and deposited by a glacier
Kettle lake
A kettle is a depression or hole in a plain formed by retreating glaciers
Drumlin
A low oval mound or small hill
