Hello,
Here is ur answer
sparta, roman empire, athens, classical greece, and greco-persian wars.
Answer:
Human activity - Produces greenhouse gasses.
Greenhouse gasses - Cause atmosphere to trap more heat.
Sun's output - Can vary.
Ice age - Peaked 20,000 years ago.
Explanation:
Human activity includes the usage of fossil fuels on a very large scale, and by using them we release huge amounts of greenhouse gasses into the atmosphere.
The greenhouse gasses have the ability to trap the heat that is reflected from the surface of the planet, thus keeping more of it in the atmosphere and causing global temperature rise.
The sun is technically a star, thus an object that produces energy and light, and like every star, it has variations in its activity in accordance with the processes going on on it.
There have been numerous ice ages through the geological past, and the last one of them ended only around 10,000 years ago, with its peak being just 20,000 years ago.

Answer:
Principle of Original Horizontality
Explanation:
- Sedimentary rocks are deposited originally horizontally under the impact of gravity. The principle of original horizontality states that layers of sedimentary rocks are under the action of gravity and are important to the analysis of the folded stilted strata. These sediments are deposited in existing surfaces.
