The process by which natural forces move weathered rock and soil from one place to another is called …. a.Deposition b.Abrasion c.Erosion
Landslides, mudflows, slump, and creep are all examples of …. a.Runoff b.Mass movement c.Soil formation
Mass movement is caused by …. a.Plucking and abrasion b.Gravity c.Erosion and deposition
A landscape in which a layer of limestone close to the surface erodes into deep valleys, caverns, and sinkholes is called …. a.Loess b.Headland c.Karst topography
A mass movement called ________ occurs when sediment suddenly slips downhill in one large mass.
The force that moves sediment in a landslide or mudflow is ________.
Water erosion begins when runoff from rainfall flows in a thin layer over the land in a kind of erosion called …. a.Mass erosion b.Creep c.Sheet erosion
A stream or river that runs into another stream or river is a called a …. a.Tributary b.Gully c.Turbulent stream
A river flowing across a wide flood plain begins to form looplike bends called …. a.Rills b.Meanders c.Outside curves
Where a river flows from an area of harder rock to an area of softer rock, the softer rock may wear away, eventually forming a drop called a …. a.Gully b.Delta c.Waterfall
A wide sloping deposit of sediment formed where a stream leaves a mountain range is called a(n) …. a.Drainage basin b.Alluvial fan c.Slump
Deltas are built up by …. a.Deposition b.Leaching c.Erosion
What type of energy is involved when a river moves sediment and erodes its banks? a.Gravitational energy b.Potential energy c.Kinetic energy
What happens as gravity pulls water down a slope? a.Kinetic energy changes to potential energy. b.Energy is stored for future use. c.Potential energy changes to kinetic energy.
Potential energy changes to kinetic energy.
What causes most sediment to wash or fall into a river? a.Deposition b.Mass movement and runoff c.Turbulence
Mass movement and runoff
How would a fast-flowing river be most likely to move sand-sized particles of sediment? a.It would lift them and carry them downsteam. b.It would dissolve them completely in solution. c.It would deposit them on the streambed.
It would lift them and carry them downstream.
As more water flows through a river, its speed will …. a.Decrease b.Increase c.Reduce friction between the water and the streambed.
The volume of water that moves past a point on a river in a given time is called the river’s …. a.Flow b.Load c.Turbulence
What is one main difference between continental glaciers and valley glaciers? a.Continental glaciers are much larger and thicker. b.Valley glaciers cause more erosion. c.Continental glaciers never melt.
Continental glaciers are much larger and thicker.
Glaciers can only form when …. a.There is an ice-age. b.The amount of snow exceeds the amount of rain. c.More snow falls than melts.
More snow falls than melts.
The process in which rock fragments freeze to the bottom of a glacier and then are carried away when the glacier moves is called …. a.Plucking b.Surging c.Abrasion
Which of the following is evidence that an area was once covered by a glacier? a.V-shaped valley b.U-shaped valley c.Alluvial fan
After the last ice age, stranded ice blocks left behind by the continental glacier melted and formed …. a.Kettles b.Drumlins c.Moraines
A ridge of till located at the farthest p0int reached by a glacier is called a …. a.Fiord b.Drumlin c.Terminal moraine
The energy that produces ocean waves comes from …. a.The rise and fall of the tides. b.Rivers flowing into the ocean. c.Wind blowing across the water’s surface.
Wind blowing across the water’s surface.
As the energy of a wave moves through the water, what happens to the water particles themselves? a.They are carried away. b.They move up and down, but do not move forward. c.They slowly move backward.
They move up and down, but do not move forward.
If waves erode the soft rock along the base of a steep coast, the result may eventually be a landform called a …. a.Fiord b.Headland c.Wave-cut cliff
Where a coastline turns and interrupts longshore drift, sand may be deposited in a fingerlike landform called a …. a.Spit b.Barrier beach c.Sandbar
As waves repeatedly hit a beach, some of the beach sediment moves down the beach with the current, in a process called ______.
The two processes by which waves erode the land are _______and __________.
impact & abrasion
The process by which wind removes surface materials is called …. a.Abrasion b.Plucking c.Deflation
Wind carrying sand grains deposits the sand when the wind …. a.Speeds up b.Slows down or hits an obstacle. c.Crosses a depression in the ground.
Slows down or hits an obstacle.
Particles of clay and silt eroded and deposited by the wind are called …. a.Till b.Loess c.Dust
In deserts, deflation can sometimes create an area of rock fragments called a …. a.Sand dune b.Loess deposit c.Desert pavement
Ocean waves contain energy that is transferred to them by ______ moving across the surface.
The main way that the wind erodes the land is by process of ______.
