Answer:
Explain how the ability to describe the pattern of ice ages over the past million years help to assess what is normal variation in the Earth's atmosphere
.
Explanation:
The description of the pattern of ice ages allows the study of climatic variations over the years. This helps to understand the normal variation in the earth's atmosphere, I understand the climate established in each season and how it influenced the patterns of life and resources in the pallet.
These descriptions are made using paleoclimatic instruments that observe elements such as the composition of the ice, the structure of the trees and possible fossils.

Answer:
4N
Explanation:
From the problem statement, the weight of the piece of stone when fully immersed in water is 18N
The stone displaces water with the weight of 4N;
So, the weight of the stone in air is 4N.
- From Archimedes principle, we know that the weight of the water displaced when an object is placed in a liquid is the weight of the object.
- This method is often used to determine the weight of objects that are irregularly shaped.
- The weight of a regular body can be easily determined.
- But for irregular bodies, immersion in a liquid is a good approximation.
