D. Rock type
Explanation:
The major factor that influences the strength of rocks is the rock type.
Different rock types are known to have their own relative strength.
Based on their strength, rocks are classified into hard and soft rocks.
Soft rock types are dominated by sedimentary rock. Sedimentary rocks are formed by accumulation and deposition of sediments. They are often layered.
Metamorphic and igneous rocks are usually classified as hard rocks. These rocks forms under very high temperature and pressure conditions.
In engineering applications, the soft rocks not desired for construction purposes although they have their own unique material functions.
Hard rocks are used for heavy duty and durable constructions like dams and bridges.

Density, because the core is made of metals like iron and nickel
<span>Ocean currents act much like a conveyer belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.</span>
