What is this landform called?

plateau

cavern

mountain

canyon

This landform was created by-

glacier

wind

landslide

water

Deposition occurs when -

sediments build up in one place as a result of the effects of wind, water, and ice.

features on the surface of the Earth are formed, such as mountains, hills, dunes, oceans, and rivers.

rock is broken down into smaller particles from the effects of wind, water, and ice.

wind, water, and ice moving weathered materials down a mountain side.

A student was observing rocks he found at a river bed. The rocks he found were smooth and rounded because they-

formed from lava during an earthquake

were part of a glacier that melted

were in a river that had fast moving water

rolled down a side of the mountain

Heavy rains fall on a farm for several months. What might the farmer notice as a result?

An increase in soil due to deposition

A decrease in soil due to erosion

an increase in temperatures due to weathering

What might cause a sand dune to move from place to place?

rushing rivers

blowing winds

freezing water

weathering rock

A canyon might be formed by

wind blowing

ice freezing

water moving

snow falling

Water drips slowly from the ceiling of a cave and and leaves minerals behind. The resulting structure is called __________.

stalactites

canyons

deposition

sand dunes

Ice can cause weathering of rocks by

holding water

breaking them

lifting sediment

cooling the wind

10.

Which of the following will most likely increase the amount of erosion that occurs on the banks of a river?

Heavy rains on the mountain that is the river’s water source.

High winds over the ocean to which the river flows.

High temperatures increasing evaporation from the river.

Ice formation at the source of the river.

11.

The illustration provided shows exposed layers of sedimentary rock in the High Plains region of Texas. Which of the following best explains the uneven nature of the exposed rock layers?

Different types of rock weather at different rates when exposed.

Wind speeds vary greatly over time in this region of Texas.

An ancient river deposited sediments at different rates over time.

Glacier movement always creates uneven rock formations.

12.

Sand bars are large deposits of sand that appear close to the shoreline of a beach. Which of the following processes is responsible for creating sand bars?

Wave action and currents

Constant light breezes

Hurricane precipitation

Aquatic organism activity

13.

In Galveston, the beaches are often exposed to hurricanes originating in the Gulf of Mexico. It is reasonable to predict that hurricane activity may -

create new rivers near Galveston.

move sand from the beach to offshore sand bars.

cause local earthquakes after the storm.

create new river deltas along the beaches.

14.

This picture shows sand dunes on Padre Island, Texas, in the Gulf Coast Prairies and Marshes ecoregion.
The sand dunes most likely formed by --

The deposition of sand carried by swift wind blowing along the coast.

strong waves dumping chunks of the ocean floor onto the beach.

a primitive river that flowed toward the ocean and carved out the sand dunes.

Land that slightly uplifted when tectonic plates moved under the beach sand.

15.

The picture shows part of the Piney Woods ecoregion in east Texas.
Which of the following best explains the lack of extremely diverse landforms in this ecoregion?

The high vegetation decreases erosion from water and wind.

The high amount of vegetation soaks up most of the corrosive water into their leaves.

The trees broke down all of the previous landforms through weathering.

The trees in this region hide the diverse landforms underneath them.

16.

The Texas High Plains region does not receive much rain. It is reasonable to predict that this region, compared to other ecoregions, would have -

less soil erosion.

larger river deltas.

many mountains.

sandy beaches.

17.

The Gulf Prairies and Marshes ecoregion experiences significant soil erosion. One would expect the climate in this region to be –

dry and hot.

cold and snowy.

wet and rainy.

warm and humid.

18.

The picture shows a map of a part of the Gulf Coast Praries and Marshes ecoregion. Which of the following best explains how these islands formed?

They formed as hurricanes deposited sand from distant regions.

They formed as underwater volcanoes erupted and deposited lava.

They formed as a reef built up deposits so high that it created an abovewater mass.

They formed as sand from the shore was deposited in a location where water movement slowed down.

19.

The Rolling Plains region of Texas has a number of deep canyons. One would expect this region to have -

moving glaciers.

deep lakes.

flowing rivers.

high wind.

20.

The Blackland Prairie ecoregion of Texas has many exposed boulders that are smooth and rounded. What feature of this area caused the boulders to take on these characteristics?

Hurricane activity

Wind-blown sand and rain

Severe droughts

Deep and rapid rivers

21.

The map shows the various ecoregions of Texas. Which ecoregion is most vulnerable to wind erosion from hurricanes originating in the Gulf of Mexico?

Post Oak Savannah

Blackland Prairies

Edwards Plateau

Gulf Prairies and Marshes

22.

Rivers carry and deposit sediments all along their course. Where will the sediments made of the largest and heaviest particles be deposited?

Near the start of the river where water travels fastest

In locations where the river banks are the widest

In locations where the river banks are the most narrow

At the river’s mouth where the river meets the ocean

23.

From the distinct shapes of sand dunes and their features in a desert, a geologist could most likely determine which of the following?

Direction of the prevailing wind

Daily high and low temperatures

Amount of water nearby

Age of the formations

24.

Emptying into the Gulf of Mexico, the Brazos River is the longest river in Texas. What type of land formation would you expect to find where the river deposits sediments as it reaches the Gulf?

A cave

A mountain
