Which of the following is the best example of a change to Earth's surface caused by a usually gradual process that is interrupted by a rapid event?

• An earthquake resulting from tectonic plate movement

• The formation of a delta at the moutn of a river

• The creation of sediments by breaking down rocks

• A flooding of wetlands caused by a hurricane's storm surge

Which of the following surface features could be caused by moving ice but not by moving water or wind?

• Transporting large boulders over many kilometers

• Smoothing and rounding rocks of different sizes

• Carving out a canyon several kilometers long

• Rivers

• Sand dunes

• Wind storms

Stalagmites are structures found on the floors of caves and are made of mineral deposits.

Stalagmites provide evidence for how moving water can change Earth materials because stalagmites--

• grow upward, while stalactites grow downward from the ceiling.

• are sometimes found in or near pools of water underground.

• may be small and delicate or very tall and massive.

• form where water containing dissolved minerals constantly drips.

Which observtions about the Rocky Mountains and the Appalachian Mountains would support the claim that exposure to weathering and erosion over time can change land forms?

• The Appalachian Mountains are found in the eastern United States and the Rocky mountains are found near the west coast.

• The shorter and more rounded Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains.

• The length of the Appalachian chain is approximatly 2,400 kilometers, and the Rocky Mountain chain is about twice as long.

• The Appalachian Mountains are composed mostly of sedimentary rocks while the Rocky Mountains also contain other rock types.
