Weathering is a term for the general process by which rocks are broken down at the Earth’s surface.

Mechanical weathering is also known as physical weathering.

Water is the main agent of chemical weathering.

3. Weathering is important because it turns rock to soil.

Industrialization decrease the rate of weathering.

Different soils may have different abilities to retain water.

The movement of rocks from one place to another is called weathering.

Different soils may have different amounts of humus.

Landslide can be caused by water, wind, animals, and humans.

Small volumes of soil and sand are transported when they are used in the construction of houses.

Which of the following is NOT a cause of weathering?

Which agent of weathering allows the rock to contract and expand?

Which combination of materials could be soil?

A cliff was formed near the ocean. Which statement best describes how this cliff was formed?

How do plants weather rocks?

It is a main agent of weathering; strong waves hitting rocks can make rocks break. Water can seep into the cracks of the rocks. When it gets colder, this water can expand and turn into ice. This can trigger rocks to break as well.

when rocks are exposed to varying temperature, it expands. If rocks are exposed to a low temperature, it contracts. The repeated expansion and contraction of rocks due to changes in temperature results in weathering.

Some plants grow on rocks and cause it to break into pieces. Eventually, metabolic or life process of these plants will cause the gradual breakage of rocks into smaller pieces.

people weather rocks in different ways. Some developers and construction workers use bulldozer and jack hammers in breaking rocks. Quarrying and mining activities can break down rocks. Dynamite blasting is done on large rocks along the mountain sides during roads construction

It is a valuable resource that needs to be carefully managed as it is easily damaged, washed or blown away. If we understand the importance of soil and how to mana it properly,we can avoid destroying one of the essential components of our environment and thus contributing to food security.
