Weathering 1

Weathering can be described as

• earthen materials are worn away and transported by natural forces such as wind or water.

• the gradual breakdown of rocks and materials in their original place.

• the movement of any solid material downhill under the influence of gravity

Which of these is NOT a type of weathering

• biological weathering

• chemical weathering

• erosion weathering

  
  

• physical weathering

Which type of climate would cause the greatest rate of chemical weathering?

• cold and humid (wet)

• cold and dry

• warm and humid (wet)

• warm and dry

Which weathering process results in rocks being broken down into smaller pieces, but not changed chemically

• mass movement

• oxidation

• chemical weathering

• mechanical weathering

These factors MUST be present for Frost Action to occur: i) fluctuating temperatures(above and below freezing) ii)exposed rocks with cracks iii)rainfall iv)burrowing animals

• i only

• i, ii and iii

• iii only

• all of the above

Which type of rain causes faster chemical weathering

• Normal rain

• acid rain

• diluted rain

What does iron react with in the process of oxidation

• sulfer

• dioxide

• oxygen

Which of the following is NOT an example of physical weathering

What are the two things that affect how fast or how slow something is weathered?

• speed and time

• type of rock and environment

• environment and minerals

• temperature and pressure
