How can plants cause the weathering of rocks?

• roots can grow into or near rocks causing the rocks to break down over a period of time.

• plants can chemically break down rocks using photosynthesis

• plant roots can use the rocks as a source of nutrients and break them down over time

• plants can release water vapor into the air that causes the rocks to break down over time.

Which of the following landforms are created over a long period of time?

• Mountains and Canyons

• Landslides and Sand dunes

• Ponds and Mountains

• Volcanic eruptions

The landform below is a sea arch. It could be included as evidence to support which of the following statements?

• Earthquakes are constructive forces that build landforms on the coast quickly.

• Waves are constructive forces that deposit sand and sediments on the coast slowly.

• Earthquakes are destructive forces that cause breakage of rock formations near the oceans.

• Waves are destructive forces that over time can wear away at the earth’s coast and change its shape.

What type of process most likely created the mountain chain seen here?

• Volcanic eruptions created the mountains over millions of years.

• Tectonic plates pushed together forcing one plate under the other and then pushing the land upward.

• Earthquakes broke the earth into pieces and parts of it fell into cracks between faults.

• A river flowed through the land and created the valleys between the mountains making them appear taller.

Deposition of sediments can change the depth of a lake over time. A student wants to make a model that shows how this process takes place. Which model would provide data about changes in the depth of a lake caused by deposition?

• Fill a beaker with water. Slowly allow the water to evaporate from the beaker. Measure the change in the depth of the water.

• Fill a beaker with wayer. Slowly drop sand, gravel, and dead plant material into the beaker. Measure the change in the depth of the water.

• Fill a plastic box with water. Put a hose in the water on one end of the box and turn the water on to a slow flow. Measure the depth of the water when the box is full.

• Fill a plastic box with sand, gravel, and dead plant material. Put a hose in the middle of the box and turn the water on to a slow flow. Measure the depth of the water when the box is full.
