Q

This primarily occurs during collision of rocks, sand, and silt due to current or waves along a stream or seashore causing sharp edges and corners to wear off and become rounded.

Q

Rock-forming minerals like amphibole, pyroxene, and feldspar react with water and form different kinds of clay minerals.

A

HYDROLYSIS

17
Q

minerals that react with water and form into diff. types of clay.

A

amphibole, pyroxene, and feldspar

18
Q

It is the response of oxygen with minerals. If the iron oxidizes, the mineral in rocks decomposes.

A

OXIDATION

example of oxidation

A

RUSTING

20
Q

is a mixture of grains, organic matter, H2O, and gas.

A

SOIL

21
Q

is the separation and removal of weathered rocks due to different agents like water, wind, and glacier that causes transportation of the material to where they are deposited.

A

EROSION

22
Q

what plays an important role in the erosional process.

A

Plants, animals, and humans

23
Q

when those sediments are deposited, or dropped off, in a different location / filed up rocks due to erosion

A

DEPOSITION
