Question

Weathering is the breakdown of rocks into smaller particles called __________
.

___________weathering is when rocks are physically broken into smaller pieces, but the minerals in the rock remain the same.

When a rock is broken down in a way that changes the mineral composition, it is called ___________ weathering.

Answer 1

Answer:

1. Weathering is the breakdown of rocks into smaller particles called Mechanical weathering (also called Physical weathering).

2. Chemical weathering is when rocks are physically broken into smaller pieces, but the minerals in the rock remain the same.

3. When a rock is broken down in a way that changes the mineral composition, it is called Physical weathering.

Answer 2

Answer:

• Weathering is the breakdown of rocks into smaller particles called Mechanical weathering .
• Physical weathering is when rocks are physically broken into smaller pieces, but the minerals in the rock remain the same.
• When a rock is broken down in a way that changes the mineral composition, it is called Chemical weathering.

Explanation:

• The breakdown or dissolving of rocks on the Earth's surface is known as weathering.
• Materials from the coastlines are broken down and removed during weathering. Weathering gradually erodes exposed surfaces.
• There are several varieties of rocks, and some of them are more susceptible to weathering than others.
• Weathering is also the initial phase in the formation of soils, as the angular or sharp edges of rocks become softened and reduced in size.
• Soil is formed when microscopic fragments of weathered material combine with plants, animal remnants, bacteria, and other things.
• Weathered materials from a single type of weathered rock make infertile soil, but weathered materials from multiple rocks form more fertile soil.
• The three forms of weathering can break down any exposed rocks near the coastline:

1. Mechanical weathering - Mechanical weathering is the process through which rocks break down into smaller pieces.
2. Physical weathering - Physical weathering is the process by which rocks are physically broken into smaller pieces but the minerals within the rock stay unchanged.
3. Chemical weathering - Chemical weathering is the process of a rock being broken down in a way that alters the mineral composition.
