Answer:
The theory of evolution basically serves to explain the biological evolution of living beings. The theory of evolution basically serves to explain the biological evolution of living beings. This results in the appearance of new species different from the previous ones.
Explanation:
Gravitational potential energy is the energy of body due to its position in the gravitational field.
Whereas chemical potential energy is the energy within the chemical bonds of a substance.
For example, when we eat an apple then we get energy in our body so, it is the chemical potential energy stored in the apple.
Items sorted on the bases of gravitational potential energy and chemical potential energy are as follows.
Gravitational potential energy:
- a ball thrown up in the air.
- a stone rolling downhill.
- water stored in an overhead tank.
Chemical potential energy:
- liquid petroleum gasoline used in cars.
- firecrackers that people set off.
-Homologous structures in different organisms
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.
