Weathering etc. Review

John helps his dad change the oil in the car.  They pour the used oil down the stormdrain. What effect will the oil have on the watershed?

• Rainfall amounts will be less
• The water in  the storm drain will flow a different direction
• Local pond life may be killed
• There will be less available space for crops

How do people affect groundwater?

• Humans drill wells and remove groundwater
• Humans do not affect groundwater because it is below ground
• Humans increase the amount of groundwater available
• Humans use groundwater for recreational purposes like boating and fishing

The process of breaking down rocks is called

• erosion 
• gravity
• weathering
• deposition

The process of moving rocks and sediment is

• weathering
• erosion
• deposition
• gravity

The process of leaving behind sediment in a new location is

• weathering
• erosion
• deposition
• gravity

Mountains with high altitude have rocks that have been broken apart.  What process would break the rocks?

• chemical weathering
• deposition of sediments by gravity
• wind erosion
• mechanical weathering

What is runoff?

• Water from rain that is not part of the water cycle
• Water from rainfall that soaks into the ground
• Rainfall that becomes groundwater
• Rainfall that does not soak into the ground or evaporate, but instead moves across the surface

The Palo Duro Canyon is pictured. How were the rock formations created?

• Deposition of sediment into layers
• Wind erosion
• Water erosion
• Weathering of the rock layers by roots of plants

Whcih of the following landforms common to Texas is created through deposition?

• Our curved coastline
• the hills of Austin and the Edwards Plateau
• The narrow barrier islands and beaches
• The canyons of the Texas Panhandle

What would students be modeling with this set up?

• physical weathering
• chemcical weathering
• weathering, erosion and deposition
• erosion and deposition
