This picture is a sea arch. As erosion from ocean waves continues, what will most likely happen to the hole in this landform?

• It will become larger
• It will fill with sediment
• it will remain the same size
• it will be covered with water

Stone Mountain in Georgia is a granite dome that formed deep underground. Over time, uplift and erosion exposed the granite. What natural activity is MOST responsible for breaking down the mountain today?

• faulting
• weathering 
• stream erosion
• lightening 

The process that moves weathered rocks is called

• erosion
• gravity
• layering 
• folding

When a volcano no longer erupts, the lava inside cools and forms

• melted igneous rock
• ash 
• cinders
• solid igneous rock

The Mississippi River deposits soil as it empties into the Gulf of Mexico. This shows an example of 

• rocks can dissolve in water
• flowing water carries soil from place to place
• salt water is denser than fresh water
• Earth's land area keeps growing

Because of the formation of new crust on its floor, the Atlantic Ocean

• is growing wider
• is getting narrower
• has few mountains
• has lost some of its fishing grounds

Waves breaking on a beach will change it over time. If sediments are moved into the ocean by wave action, 

• the beach will eventually decrease
• the beach will eventually increase
• the beach area will eventually become more level
• the particles on the beach will eventually become smaller

Changes in the Earth's crust can be slow or fast. Which of these is the BEST example of a slow change?

• volcanic erruption
• weathering
• landslide
• earthquake

Mr. Gonza owns a large farm in southwestern Georgia. This year, he plans to leave several fields fallow (without crops). What should Mr. Gonza do to prevent soil erosion on the empty fields?

• plant grass to hold the soil
• water the empty fields regularly 
• fertilize the soil throughout the growing season
• plow the soil deeply and regularly

A mountain range is MOST LIKELY formed due to 

• erosion of the land around a mountain
• deposition from a nearby river that results in soil accumulated over time
• they have always existed, but due to their density, they are never changed
• tectonic plates shifting during an earthquake
