Help me!!! Several small craters lie in the floor and on the walls of crater 2. Which is older,crater 2 or the smaller craters inside it?

Answers

Answer 1
Answer: Well, think of it this way. If you put a big paper circle on the ground, and then you put smaller circles on top of the big circle, which one would have been there longer? The big circle, of course. So the same logic applies here: if the smaller craters had been older than the big crater, then when the big crater was formed, the smaller ones would've been buried. Therefore, crater 2 is older than the smaller craters inside it.
Hope that helped! =)

Answer:

A. Add sand

Explanation:

A mixture in which particles are not uniformly distributed throughout the solution then it is known as a heterogeneous mixture.For example, sand in water is a heterogeneous mixture.Where as a mixture in which particles are evenly distributed throughout the solution then it is known as a homogeneous solution.For example, salt in water is a homogeneous solution. This, is why we can conclude that to make salt water a heterogeneous mixture, you would have to add sand.
