Question 14

basin and range

Answer 14

normal faults

Question 15

earthquakes

Answer 15

quick release of stored potential energy into motion

richter scale=log scale

Question 16

physical weathering

Answer 16

unloading
thermal explansion
frost cracking
root intrusion
wetting and dyring

Question 17

chemical weathering

Answer 17

osidation
dissolution=karst topography
hydrolisis=dissocles ions or new minerals form
increase in temp adn percipitation increases chemical weathering

Question 18

controls of chemical weathering

Answer 18

chemical reactions-easily remove ions
increase temp + percipitation= increase in chemical weathering
rock type
surface area

Question 19

weathering

Answer 19

creates new landscapes

Question 20

understanding weathering rates

Answer 20

can help us in the future in agriculture and being sustainable

classifying mass movements

Answer 21

speed and water content

Question 22

four types of mass movements

Answer 22

falls
slides
flows
soil creep

Question 23

controls and triggers

Answer 23

increase in water content
earthquakes
weathering
land use changes
wild fire

Question 24

forces controling transport downslope

Answer 24

driving forces-mass material, slope angle

resisting forces- strength of material

Question 25

anatomy of river

Answer 25

floodplain streambank streambed stage:height of flow

Question 26

types of rivers

Answer 26

bedrock alluvial -multiple channel-braided -single channel-straing-meandering

Question 27

ways to get to streams

Answer 27

``` direct percipitation surface runoff infiltration interflow percolaion baseflow ```

Question 28

streamflow measured

Answer 28

Q=area x flow velocity | Q=streamflow

Question 29

sediment transport

Answer 29

saltation- hoping traction-sliding suspended load- above bed sand or clay

Question 30

discharge sediment size and river slope

Answer 30

as discharge, velocity, depth increase the aility to transport sediment increases

Question 31

lanes balance

Answer 31

degredation=erodes rivers | aggradation=sediment deposites
