Answer:
They occur in thousands of years or within billions of years.
They affect populations and species more slowly than short-term changes.
They can affect the DNA of living things over time.
Explanation:
A long term environmental change is the change which exerts it's impact for a long time period about billions of years. It leads to the destruction of the environment at a slow or rapid pace. It makes the environment unsuitable for the survival of the living beings. The living beings either adapt to the change or they may migrate to new locations or they may extinct. The changes in the environment brings drastic changes in the morphology, physiology and genome of the living organisms.
On the basis of the above explanation, the following are the correct options:
They occur in thousands of years or within billions of years.
They affect populations and species more slowly than short-term changes.
They can affect the DNA of living things over time.
The statement that describes long-term environmental changes are occur in thousands of years or within billions of years, they affect populations and species.
Environmental change is a term used to describe a change or disturbance in the environment that is generated by both human and natural ecological processes.
A long-term environmental change is one that has an impact over a lengthy period of time, such as billions of years. It leads to the gradual or quick degradation of the ecosystem. It degrades the environment, making it unfit for human survival. Adapting to the change, migrating to new regions, or going extinct are all options for living beings. The morphology, physiology, and genetics of living organisms are all affected by changes in the environment.
Hence long term environmental changes are occur in thousands of years or within billions of years, they affect populations and species more slowly than short-term changes and they can affect the DNA of living things over time.
