3
Which of the following is not a type of sedimentary rock?

4
What is the difference between weathering and erosion?
Weathering breaks rocks and erosion adds sediments to rocks
Erosion breaks rocks and weathering carries sediments away
Weathering breaks rocks and erosion carries sediments away
Erosion breaks rocks and weathering adds sediments to rocks
5
What are crystalline sedimentary rocks?
Rocks made from precipitate crystals
Rocks made from cooling lava
Rocks made from cooling magma
Rocks made from compacted biological matter
6
Which of the following is not a type of physical or mechanical weathering?
Roots from plants breaking open rocks
Reaction of elements of the rock with the environment
Freezing and thawing of ice during Ice Wedging
Abrasion from wind and water
7
How does the freezing of water into ice break down rocks in Ice Wedging?
Frozen water falls as hail and hits rocks to break it down
Frozen glaciers abrade against rocks as the glacier moves
Water inside cracks of rocks expand when frozen, breaking open the rock
Ice on rivers abrade against rocks and break it down

11
What are bioclastic sedimentary rocks?
Rocks made from compacted organic matter
Rocks that have been changed following pressure and heat
Rocks made from cooling magma
Rocks made from cooling lava
12
Which of the following is an example of chemical weathering?
Reaction of iron in rocks with oxygen
Washing away of sediments by rivers
Abrasion of rocks by glaciers
Breaking down of rock from plant roots
13
