A river flowing across the rocky surface of the Earth could create which of the following?
Dunes
Mountains
Canyons
Hills
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 to blow piles of sand.
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
Which of the following landforms is the result of a river carving out land by erosion?
Canyon
Sand dune
Delta
Mountain
Canyons and deltas are similar in that both form -
due to the action of moving water
high in the tallest mountains
where lots of sediments collect
in and around active volcanoes
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
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
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
What is a canyon?
A deep ravine between cliffs that is most often carved from the landscape by a river
A triangular landform where a river empties into another body of water
The buildup of land by the settlement of sediment and soil in a new location
A feature on the surface of Earth such as a mountain, hill, dune, ocean, or river

What is erosion?
The buildup of land by the settlement of sediment and soil in a new location
The removal and movement of sediment from one place to another by gravity, water, wind, or ice

What is a sand dune?
A feature on the surface of Earth such as a mountain, hill, dune, ocean, or river
A hill formed by wind blowing and depositing sand

A deep ravine between cliffs that is most often carved from the landscape by a river
What is a landform?
A feature on the surface of Earth such as a mountain, hill, dune, ocean, or river
The breakdown of rocks into very small particles by gravity, water, wind, and ice
The removal and movement of sediment from one place to another by gravity, water, wind, or ice
The buildup of land by the settlement of sediment and soil in a new location

How did the delta at the end of the Rio Grande form?
Sand and mud from the Gulf of Mexico were washed ashore by tsunamis
The river cut through the solid bedrock of the valley.
Hurricanes pushed soil and debris from the Gulf of Mexico onto the land.
The river deposited large amounts of sediment from land erosion.

How do plants weather rocks?
Cómo afectan las plantas a las rocas
Plants don't weather rocks.
When roots grow into cracks of rocks and expand the rock breaks.
When the plant moves water from the roots to the leaves, the rock breaks.
