WEATHERING

Question 1

This is the on-site breakdown of rock and its eventual transformation into sediments?

Answer 1

WEATHERING

Question 2

WHAT ARE THE TWO TYPES OF WEATHERING?

Answer 2

1. Mechanical weathering
   2.Chemical weathering

Question 3

It is the physical breakdown of a rock into unconnected grains or chunks without changing its composition?

Answer 3

MECHANICAL WEATHERING

Question 4

It is the chemical changes in some of the composition of the rock. This process is not influenced by high temperature or pressure?

Answer 4

CHEMICAL WEATHERING

Question 5

Due to pressure, layers of rock begin to crack, and outer layers begin to peel away layer by layer, like an onion.

Answer 5

Exfoliation

Question 6

Waters in cracks of rocks freezes, causing joints to expand. When it thaws, it causes pieces of rocks to detach.

Answer 6

Frost Wedging

Question 7

Roots force themselves into tiny cracks. Putting pressure on it as they grow, and eventually breaking the rock.

Answer 7

Root Wedging

Question 8

Saltwater seeps into rocks and grows as crystals, which causes cracks to widen. Rocks weaken and eventually break.

Answer 8

Salt Wedging

Question 9

When exposed to high temperature, it expands and as it cools, it contracts. This repetitive process causes rocks to weaken and break-off into sheets.

Answer 9

Thermal Expansion

Question 10

Happens when certain minerals which are dissolved
in water.

Answer 10

Dissolution

Question 11

Occurs when water reacts with the minerals and breaks them down and have a clay-like texture.

Answer 11

Hydrolysis

Question 12

Reaction of oxygen with minerals in the rock, forms oxides.

Answer 12

Oxidation

Question 13

Occurs when water is absorbed into the crystal structure of the mineral, causing it to expand.

Answer 13

Hydration

Question 14

Occurs in roots of plants. When fungi and lichens secrete acids that dissolve minerals, the nutrients are taken in by these organisms.

Answer 14

Biological Weathering
