What is weathering of rocks in simple words?
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
How do you explain weathering to a child?
Weathering is a natural process that slowly breaks apart or changes rock. Heat, water, wind, living things, and other natural forces cause weathering. Over many years, weathering can shape rock into unusual formations.
What is an example of weathering for kids?
The Earth’s surface gets broken down through weathering. Rainwater can easily enter cracks in rocks or sidewalks. If this happens during cold months, the water may freeze and expand in the crack. Working as a wedge, the ice splits the rock. Many times, road crews have to patch up potholes caused by weathering from ice.
How does weathering of rocks happen?
Weathering happens through processes or sources in the environment, including events like wind and objects like the roots of plants. Weathering is either mechanical, in which rocks are broken down through an external force, or chemical, which means rocks are broken down through a chemical reaction and change.
What are examples of weathering?
Weathering is the wearing away of the surface of rock, soil, and minerals into smaller pieces. Example of weathering: Wind and water cause small pieces of rock to break off at the side of a mountain. Weathering can occur due to chemical and mechanical processes.
What are 5 things about weathering?
Fun Facts about Weathering for Kids
- Rain is mildly acidic and it slowly eats away rocks.
- Plants and microbes also attack rocks.
- In cold areas, water seeps into cracks in the rocks during the day.
- In the desert, rocks expand during the heat of the day and contract at night when temperatures cool.

What is the best example of weathering?
Weathering is the wearing away of the surface of rock, soil, and minerals into smaller pieces. Example of weathering: Wind and water cause small pieces of rock to break off at the side of a mountain.
What are 5 types of weathering?
5 Types of Mechanical Weathering
- Plant Activity. The roots of plants are very strong and can grow into the cracks in existing rocks.
- Animal Activity.
- Thermal Expansion.
- Frost action.
- Exfoliaton.
What are 10 facts about weathering?
How is mechanical weathering used to break up rock?
Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering. Water gets into cracks and joints in bedrock.
How does organic weathering help to cause erosion?
Organic weathering happens when plants break up rocks with their growing roots or plant acids help dissolve rock. Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity.
What do you need to know about weathering processes?
Weathering is the process where rock is dissolved, worn away or broken down into smaller and smaller pieces. There are mechanical, chemical and organic weathering processes. Organic weathering happens when plants break up rocks with their growing roots or plant acids help dissolve rock.
What are the lessons in the weathering instructional case?
The Weathering Instructional Case (IC) consists of a series of five lessons and formative assessments that focus on the physical and chemical weathering of rocks and minerals. This IC was written by a team of middle school science teachers in the Integrated Middle School Science (IMSS) Partnership funded by the National Science Foundation.
