True or false? Gravity causes water to flow from higher to lower ground.
True
pillars of rock left behind by wave erosion
sea stacks
movement of large particles that roll along the bottom of a body of water
traction
Weathering due to????
acid rain
Name the two ways glaciers erode
plucking and abrasion
erosion of a sea arch can form a:
sea stack
Small sediments carried high in the air move by:
suspension
movement of larger particles that move in little jumps near the bottom of a stream
saltation
True or false? Landslides cause a tiny amount of damage compared to other natural disasters.
False
The gradual movement of soil downhill is called:
creep
Small particles are carried and stay mixed with water
suspension
Large sediments are pushed along the ground by wind in a process known as:
traction
A process that breaks up rocks, but does not change the chemical composition of the rock.
physical weathering
Breaking down rocks is known as:
weathering
What type of soil typically is responsible for a mudslide
clay
Wind-blown sand polishes rocks in a process known as:
Abrasion
True or false? Slump creates crescent-shaped scars.
True
True or false? Runoff causes erosion.
True
sediments frozen to the bottom of a glacier scrape the underlying rock
abrasion
What is it called when sediments are picked up by glaciers and freeze to the bottom?
plucking
freeze-thaw is chemical, biological or physical?
physical
medium-sized sediments carried close to the ground and move in short hops
saltation
when a cliff is eroded on both sides by waves forming a hole, this forms
sea arch
Acid rain breaks down rocks chemically, biologically, or physically?
Chemically
Burrowing animals weather chemically, biologically, or physically?
biologically
True or false? An earthquake can trigger a landslide.
True
