Answer: The answer is Core Samples, Earthquakes, S waves, and Rock composition.
Explanation:
It’s talking about study the whole interior of Earth not just one part el to learn about the Earth they have to study the rocks. The waves allow us to know whether or not the the outer core is liquid I believe. The Earthquakes shake the Earth allowing us to get new rocks.

a half life would be 0.50 for carbon 14
The answer is; C
Use the Hardy Weinberg equiation for population in assumed equilibrium. ( p+q = 1)
If p = 0.3 then q=1-p = 1-0.3 = 0.7
People who are heterozygous for the disease are represented by 2pq = 2 * 0.3 * 0.7
0.42
