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.

Answer:
the rocket average speed is 12 kilometers per second
Explanation:
Given that
The distance is 1140 km
And, the time is 95 seconds
We need to determine the average speed in kilometers per second (km/s)
So as we know that
Speed = distance ÷ time
= 1,140 km ÷ 95 seconds
= 12 kilometers per second
hence, the rocket average speed is 12 kilometers per second
The focus of an earthquake is the point underground where rocks first begin to move. Seismic waves travel outward from the earthquake's focus.
Answer:
E.
Explanation:
This is because it is always hot and dry in the deserts, so plants and animals are <u>adapted</u> to that. Hope this helps!
The main sources are humans which is why it is stated that the global warming is man made. The levels have increased beyond all measure, increasing since the 1950s by a 100 CO2 parts per million, and it keeps increasing by 2ppm on a yearly basis. The statistics from the industrial revolution era are not much different and show how much we've increased the CO2 in modern times.
