Mass movement
how does gravity effect mass movement?
Gravity drives mass movement by pulling material downslope, with the force of gravity resolving into components that either hold a mass on a slope or pull it downward
Where does wind occur?
in Earths almost sphere, everywhere
How do glaciers form?
Glaciers form over many years when annual snowfall exceeds melt, causing snow to accumulate and become compressed into dense ice
what Are the four main types of mass movement?
slumping rockslide mudslide and landslide
how does wind occur?
Wind comes from the sun's uneven heating of the Earth's surface
How do glaciers modify landscapes?
Glaciers change the landscape through erosion, transportation, and deposition
how do mass movements effect people?
Mass movements affect people through direct damage to lives and property, crushing by burial, and destruction.
How does wind effect temperature?
Wind affects temperature by transporting air masses and by creating a wind chill effect, which makes it feel colder than the actual air temperature
What are some similarities between valley glaciers and continental glaciers?
Valley and continental glaciers are similar because they both form from the accumulation of snow, erode and transport sediment through processes like plucking and abrasion, and deposit this material to form various landforms
what are 3 factors that effect mass movements?
gravity, slope steepness, and water content, along with geology, vegetation cover, seismic activity, and human activities like construction and deforestation.
What is wind?
Wind is air in motion, caused by differences in air pressure.
What are the differences between valley glaciers and continental glaciers?
The main differences are that valley glaciers are long, narrow, and confined to mountain valleys, while continental glaciers are vast, thick ice sheets covering large land areas
where does mass movement occur?
any slope-like area
what are some natural disasters that include wind?
(name 2)
Natural disasters that include strong winds are tornadoes, hurricanes (also called typhoons or tropical cyclones), derechos, and other powerful windstorms
Where do they form?
Glaciers form near earths poles(south and north) and in mountainous areas at high elevations
