Constructive and Destructive Forces

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.

Sand dunes can be viewed in the picture. What is the best way to simulate the formation of sand dunes?

• Use a hair dryer to blow sand into piles showing how wind can deposit sand in new locations.

• Use ice to move sand from one place to another the way that a glacier would on the earth's surface.

• Use water and sand to show how water can move sand from one place to another through the process of erosion.

• Use sand and a shaky table to show how earthquakes can move parts of the earths surface.

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.
