Why would a farm be best placed upstream from a factory?

The water at the highest point of the river will have been impacted the least by human activities, so it should be the cleanest

Farms do not have a negative impact on watersheds, so they should be placed upstream

The factory puts pollution in the air, so it does not matter where the farm is located

The farm should be placed upstream because pesticides from the farm will end up in the river, which is beneficial for the factories downstream

A flash flood came on quickly in an ecosystem. How would this impact the ecosystem? Choose 2!

Animals will either perish (die) or be relocated to new habitats after a flash flood

The ecosystem will rebuild through a process known as secondary succession when minimal life and soil remain

All organisms will perish (die) in the wake of the flash flood

The ecosystem will rebuild through a process known as primary succession when all life and soil is destroyed

Lichen will begin the process of creating soil by breaking down rock left over after a flash flood

Which of the following matches with deposition?

Tree roots breaking apart concrete

Canyons running through Big Bend

How is mechanical weathering different from chemical weathering?

Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.

Chemical weathering happens over much shorter time frame than mechanical weathering.

Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.

Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.

Which of the following is a cause of chemical weathering?

The freezing and thawing of water.

Sandblasting by wind-blown sand.

What is the significance of weathering in the rock cycle?

C) It breaks down rocks, providing materials for sedimentary rocks

A) It marks the end of the rock cycle

B) It is the process that forms new rocks

D) It has no significance in the rock cycle

What is the main difference between weathering and erosion?

C) Weathering is the breakdown of rocks, while erosion is the movement of weathered material

A) Weathering involves the movement of rocks, while erosion does not

B) Erosion involves the chemical breakdown of rocks, while weathering does not

D) There is no difference; they are the same process

How does temperature affect weathering?

C) Fluctuating temperatures can cause physical weathering

A) Higher temperatures reduce chemical weathering rates

B) Temperature has no effect on weathering

D) Lower temperatures increase erosion rates
