A river flowing across the rocky surface of the Earth could create which of the following?
Dunes
Mountain
Canyon
Hill
How could students best model the formation and movement of dunes?
Pour water over piles of sand.
Slowly drip wet sand into a tub of water.
Use a spoon to dig a hole in a tray of sand.
Use straws and blow piles of sand.
Students propped up one end of a tray of sand. They also set up a water jar and rubber hose siphon system, so that water flowed over the sand. They observed how the moving water carried the sand downhill and made a small pile of sand at the bottom of the tray. When the students created the small pile of sand at the end of the flow of water, they modeled the formation of which of the following?
Dunes
Canyon
Plain
Delta
What natural force formed the Grand Canyon by slowly cutting through the rock over many millions of years?
A boulder
A glacier
A river
A landslide
A delta is made of sediments deposited at the mouth of a river. A delta forms where the river meets the ocean because the ocean -
makes the river slow down and deposits sediment
contains salt water and rivers have fresh water
is usually much colder than the water in the river
has powerful currents that weather rock on the shore
Sand dunes are created when sand is moved and deposited by –
strong, persistent winds
slow moving sheets of ice
frequent lava flows
powerful ocean currents
Rivers create landforms as they move across the surface of the Earth. Rivers move as water flows from -
high in the mountains, down to oceans and lakes
regions that have warmer temperatures to cooler ones
because they are pushed by strong winds
from east to west as the earth rotates
A delta is made of sediments deposited at the mouth of a river. The delta is formed when –
moving water slows down
blowing winds cool the land
drifting clouds produce rain
crashing waves erode soil
Freeport, Texas, is built on a growing delta at the mouth of the Brazos River. The land on which Freeport is built continues to grow because the Brazos River –
deposits new material on the delta
removes sediments from the delta
moves farther away from the delta
receives fresh water from the delta
Which forces create landforms such as deltas, dunes, and canyons?
Volcanic eruptions
Earthquakes and landslides
Planetary movements
Moving wind and water
