W.E.D and Sedimentary Rock

The process that breaks down rocks and other materials on Earth's surface is called

• weathering
• erosion
• soil conservation
• decomposition

Which agents  break down earth materials?

• wind only
• earthquakes and gravity
• ice and 007
• wind, water, and ice

Glaciers are masses of ice that move slowly on land. Which of these features was most likely formed by a glacier?

• A wide valley
• A deep ocean
• A lava flow
• A mountain range

Canyons on Mars look similar to canyons on the Earth. This similarity may indicate that Mars once had -

• high winds
• rivers
• large floods
• glaciers
  

The type of formation shown is at the southern end of the Mississippi river. What is it called?

• coastal erosion
• a delta
• a loess
• sand dunes

Which of the following actions causes the deposition of sand at a delta?

• river water slowing as it enters the ocean
• salt water & fresh water mixing together
• ocean waves transporting sand toward land
• ocean water slowing as it reaches the coast

What is the movement of soil from one place to another?

• weathering
• deposition
• discharge
• erosion

Small, solid pieces of materials from rocks or living things

• sediment
• clastic rock
• organic rock
• deposition

The process that presses sediments together

• clastic rock
• cementation
• compaction
• deposition

Wind and water have eroded this rock to show the layers of sediment that were laid down millions of years ago. What type of rock is this?

• Sedimentary
• Igneous
• Metamorphic
