weathering/erosion/depostion

Question 0

types of weathering

Answer 0

physical-aka mechanical

chemical

Question 1

weathering

Answer 1

chemical/physical break down of rocks on or at earths surface into smaller sediments
occurs when rocks r exposed to the hydrosphere or atmosphere

Question 2

physical weathering

Answer 2

when rocks crack split or break into smaller pieces known as sediments
common in moist climates with wide temp ranges

Question 3

types of mechanical weathering

Answer 3

frost action
abraison
exfoliation
plants and animals

Question 4

frost action

Answer 4

breakup of rocks caused by alternating freezing and thawing of water
common in cold wet climates

Question 5

abraison

Answer 5

wearing down of rocks as they rub or bounce against one another
dry windy areas, common under glaciers

Question 6

exfoliation

Answer 6

peeling away of large sheets of lossend material at the surface of a rock

Question 7

chemical weathering

Answer 7

rock is broken down by chemical action, which results in a change of the compostion of the rock
warm moist climates

Question 8

types of chemical weathering

Answer 8

oxidation
carbination
organic decay

Question 9

oxidation

Answer 9

oxygen uniting chemically with minerals RUST YO

Question 10

carbination

Answer 10

co2 unites chemically with minerals
when co2 is dissolved in water it forms weak carbonic acid which dissolved limestone
creates KARST TOPOGRAPHY

Question 11

organic decay

Answer 11

acids from dead plants and animals disolve rock

Question 12

what effects the rate at which rocks r weathered

Answer 12

particle size( the smaller the faster)

mineral comp(the harder the slower)

climate(hotter and wetter the more chemical westhering, cool and wet more physical)

Question 13

erosion

Answer 13

MOVEMENT of weathered sediment

Question 14

agents of erosion

Answer 14

gravity( mass movemnt)
wind(angular, sorted, based upon speed of wind)
glaciers(move everything in their path, unsorted sediment)
runninng water(smooth, rounded)
waves( sorted sediment picked up by waves)

Question 15

ways water carries sediment

Answer 15

insolution
bouncing
floating

Question 16

depostion

Answer 16

DROPPING OFF of sediment

Question 17

factors effecting rate of depositon

Answer 17

density(more dense the faster)

shape(rounder the faster)

size( bigggrr the faster)
