- Chemical weathering is acid rain. If it rains onto carbonate rocks e.g. limestone, they undergo a chemical reaction. This breaks down the rock.
- Biological weathering is animals and plants. Rabbits burrow under rocks which weakens them. Tree roots grow through rocks and weaken them. Weak rock breaks up easily.

Asked in Earth Sciences, Similarities Between
What are the similarities between biological weathering and chemical weathering?
Weathering is weathering, no matter how it occurs. Both chemical and biological weathering wear down rock. They simply go about it in different ways. ...
Asked in Geology
What are the 3 types of weathering?
Chemical Weathering Biological Weathering Physical Weathering Weathering is the breakdown of rocks at the Earth's surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological. ...

What is the difference between physical chemical and biological weathering?
physical weathering is freeze thaw and exfoliation or onion skin weathering, chemical weathering is acid rain and biological is plants and animals. ...
How are chemical and biological weathering different?
Chemical and biological weathering are different because: a) biological weathering - this means that if a seed of a plant gets coincidentally deposited in a crack in a rock, if it is humid enough, the see will grow. it's roots will spread out and eventually break the rock. b) chemical weathering - this means that chemicals in rain/acid rain weathers away the rock. ...
Asked in Geology
A growing plant can cause what kind of weathering?
Growing plants can cause both physical and chemical biological weathering. An example of physical (mechanical) biological weathering would be the growth of plant roots in rock crevices which pry the rock apart. Chemical biological weathering would be the production of acids by certain plants which cause a chemical change in a rock's surface chemistry. ...
What is the difference between siliciclastic and chemical or biochemical sedimentary rocks?
1) Chemical and biological sedimentary rocks are produced by chemical weathering instead of the siliciclastic sediments which are created by physical weathering. Because physical weathering is much more often than the chemical weathering there are 10 times more clastic sediments in the earth's crust than chemical and biological sediments. ...
