What sequence shows the events that lead to the development of a river delta?

• erosion - deposition - weathering- delta
• weathering-erosion-deposition-delta
• deposition-erosion-weathering-delta
• erosion-weathering-deposition-delta

Which of the following would cause the steep sides of a canyon to form?

• the folding of rock layers
• the freezing and thawing of water
• the eruption of volcanoes
• the faulting of rock layers by earthquakes

If we were to pour water faster and slower on our stream tables and measure how much sand moved what would we be observing?

• That faster moving water makes sand stick to the bottom
• That the slower-moving water makes sand float
• That slower-moving water erodes more earth materials than faster moving water
• That the faster-moving water erodes more earth materials than slower moving water.

Over long periods of time, deposition may change the Earth's surface by...

• forming new land features
• breaking down large rocks into smaller ones
• washing away beaches
• severely draining topsoil

An estuary is a partially enclosed body of water. They are created where freshwater rivers mix with saltwater oceans. How do tides affect an estuary?

• tides strike the shoreline causing erosion
• tides cause the shape of the estuary to change
• tides change the amount of ocean water than flows into the estuary
• tides cause damage to the ocean shore along the banks of an estuary

How do waves effect a barrier island?

• waves change the shape or position of the barrier island
• waves change the amount of salt water on the barrier island
• waves change the amount of fresh water on the barrier island
• waves do not affect barrier islands

How can people help protect Earth's land and oceans?

• reduce the number of laws that prevent illegal dumping
• dumping polluted liquid into the river or ocean
• cutting down trees to allow erosion and weathering
• reduce the amount of pollution by recycling. 

People depend on oil and natural gases for energy.  The problem is it leads to increased pollution! What could we do to lessen this impact?

• Find and use alternative energy sources
• drill where there are no living organisms
• allow only small ships to drill
• only drill on land

How are canyons formed?

• constructive forces lift the land around the canyon
• people dig along the river beds and build it
• lava from volcanoes flow through the channel and erode away the earth material
• natural elements such as water, wind, and ice remove earth material and leave a v-shaped valley. 

What words BEST describe how canyons are formed?

• deposition and cartographers
• erosion and destructive forces
• meander and rivers
• plateau and landforms
