MAY THE FORCE OF MOVING WATER BE WITH YOU
ROLLING ON A RIVER
ICE, ICE BABY
ICE POWER
100
The ability to do work or cause change
What is energy
100
A river will flow faster when this is steeper.
What is slope
100
Most sediment enters a river in one of two ways. Name one.
What is mass movement or runoff.
100
A large mass of ice that moves slowly over land.
What is a glacier.
100
A glacier deposits sediment when it does what?
What is melts.
200
Energy that is stored and available to be used later.
What is potential energy
200
When there is a higher volume of flow, a river will run ______
What is faster
200
The amount of sediment a river can carry.
What is load
200
This type of glacier spreads out over large areas and currently covers about 10% of the Earth's surface (most of Greenland and Antarctica).
What is continental glacier
200
As a glacier moves across the land, it picks up rocks which freeze to the bottom in this process.
What is plucking.
300
Energy that an object has due to its motion.
What is kinetic energy
300
A river will run faster when the depth of the river is ______
What is deeper
300
Large sediment will move this way in a river.
What is dragged or rolling along the bottom.
300
This type of glacier forms high in a mountain. It stays narrow and long and is held in by the sides of mountains.
What is valley glacier.
300
As a glacier moves the sediment on the bottom scratches and gouges the bedrock. This is called:
What is abrasion .
400
As water is pulled down a slope, this type of energy is changed in to this type of energy.
What is potential and kinetic
400
A river will run faster if the streambed is this texture.
What is smooth
400
Clay or silt will travel this way in a river.
What is dissolve in the water.
400
A time in the past when continental glaciers covered large parts of the Earth's surface.
What is an ice age.
400
The sediment that glaciers deposit is called...
What is till.
500
This force pulls water down a slope
What is gravity
500
When rocks or other obstacles cause the river water to move every which way instead of downstream.
What is turbulence.
500
Medium pieces of sediment move this way in a river.
What is bounce
500
A glacier forms where?
What is in an area where more snow falls than melts.
500
When a valley glacier moves suddenly it is called?
What is a surge
