Students were tasked with making a model of how natural forces can change the surface
features of Earth. They make a pile of sand in front of an electric fan and turn it on. This model best represents which of the following changes to the surface of Earth?
The formation of a delta at the mouth of a river.
The building of a mountain on the edge of a continent.
The movement of dunes caused by the blowing wind.
The creation of a canyon by flowing water.
Stalagmites are structures that form on the floor of some caves. Most scientists explain this by saying that stalagmites form when minerals dissolved in water are left behind where water drips. Which evidence would support this explanation?
Freezing water turns it into a solid.
Water found in caves has minerals in it.
Some stalagmites are taller than others.
Many caves are found deep underground.
Over many years, the depth of a lake gets more shallow. What could cause this change?
The climate in the area gets warmer.
Sediments are deposited in the lake.
The Sun evaporates the water.

The surfaces of old concrete statues are often covered with small holes or pits. Which of these MOST LIKELY causes these holes or pits?
The concrete becomes pitted as water freezes in small cracks in the statue.
The concrete is chemically weathered by acid rain.
