Answer:
Antarctica is the driest continent; it is almost entirely desert. Very little snow or rain falls on the continent, but because it is so cold, the small amount of precipitation that does fall does not melt.

Answer:
i think it is helium is burned oxygen and helium is light
Answer:
A. Rock is heated near the core at Point A, and therefore becomes less dense. It rises towards Point B. As it moves from Point B to Point C, it is cooled and becomes denser, so it sinks at Point D.
Explanation:
The process illustrated is a convection current, something seen places like the earth's mantle and atmosphere. The hotter matter gets, the more excited its molecules become and the more they become expanded and distant from each other. (Bear in mind that there is the same amount of matter but it takes up more space, i.e. less dense). This is because the molecules are excited by the thermal energy and bounce off each other, pushing them apart.
Cold, closer to the surface (or outer space in terms of air), in turn causes the matter to shrink back into itself, which leads to the increase in density that causes it to sink and repeats the process.
Answer:
LCM = 40320
Explanation:
This question is incomplete as we are not told the numbers that was used to derive the HCF.
Let's consider the following question:
The HCF of two numbers 2880 and 2688 is 192. What is the LCM?
Solution:
HCF means = highest common factor
LCM = lowest common multiple
Find attached the solution to the question.
The HCF is found by Picking the factors (prime numbers) common to both numbers. These factors are multiplied together to get the highest common factor.
The LCM is found by picking the factors common to both numbers and the remaining factors not common to both. These are then multiplied to get the lowest common multiple of the two numbers
In this case, the factors common = HCF = 2×2×2×2×2×2×3
Factors not common to both numbers =2×3×5×7
the LCM = 2×2×2×2×2×2×3 ×2×3×5×7
= 2×2×2×2×2×2×2×3×3×5×7
LCM = 40320
