Constructive & Destructive Forces TEST

What are the two main sources of energy that power Earth?

• Heat from inside the Earth
• Wind as it travels around the Earth
• Heat from machines using Fossil Fuels
• Heat from the Sun
• Heat from evaporation of the oceans

The four main systems of Earth are:

• Atmosphere
• Geosphere
• Biosphere
• Hydrosphere
• Magnetosphere

The course of a river changed over a period of 100 years, as shown in the before and after diagrams below. Which two factors most directly caused this change over time?

• wind and rain
• freezing and thawing
• erosion and deposition
• condensation and evaporation

Where would you find a stalactite?

• On a cave floor
• On a floodplain
• On the top of a mountain
• On a cave ceiling
• Floating on the creek

What can a river create through erosion? Select all that apply.

• Valleys
• Waterfalls
• Flood Plains
• Meanders
• Oxbow Lakes

The process by which natural forces move weathered rock and soil from one place to another is called what?

• Chemical Weathering
• Physical Weathering
• Erosion
• Deposition
• Transpiration

Sediment deposited where a river flows into an still body of water is called a(n)...

• alluvial fan
• stalagmite
• oxbow
• stalactite
• delta

Two students designed the experiment shown below to study stream erosion. A steady stream of water flows from the faucet into a tray holding sand and gravel. The water forms a channel by eroding some of the sand and gravel. How can the students increase the amount of sand and gravel being eroded?

• By increasing the water temperature.
• By adding coarse gravel (bigger rock pieces) to the tray.
• By increasing the tilt or slope of the tray.
• By reducing the amount of flowing water from the faucet.

Karst Topography, such as an underground cave or cavern, is created by...

• Mass movement erosion
• mass movement deposition
• groundwater deposition
• groundwater erosion

It is harder to read the wording on very old tombstones than it is to read the wording on newer ones. This difference is most likely a result of:

• dirt filling in the letters
• modern tombstones being made of artificial materials
• weathering of the stone
• slow crystallization of the stone.
