Answer:
D. historical geology involves the study of rock strata, fossils, and geologic events, utilizing the geologic time scale as a reference; physical geology includes the study of how rocks form and of how erosion shapes the land surface
Explanation:
The geology can be separated into two sub-disciplines; physical geology and historical geology. The physical geology is the part of geology that has the present in its focus. It is examining the formation of the rocks, the volcanic eruptions, the earthquake activities, and even the effects of the pollution. On the other side, the historical geology is focused on the past. This part of the geology uses the geological time scale as its reference. It is examining the layers of the rocks, and through it tries to explain what happened in the past, how were the geological processes working. Also, the fossils are one of the main focuses because they provide lot of information about the environment in which they lived.

Answer:
When the magma, a molten rock flows as lava at the planet's surface, the surface gets cooled after a long, this whole process cause formation of some kinds of minerals on that surface.
Explanation:
Magma and Lava both are types of molten rock. The underground molten rock is called magma while the exploded molten rock on surface is known as lava. When these rocks cools down they get solidified and form crystal rock structure. Cooled magma is called plutonic igneous rock and cooled lava is called volcanic igneous rock. These rock crystals are of different sizes and consist several minerals such as Silicon(Si), Sodium (Na), Potassium (K), Aluminium (Al), Iron(Fe), Magnesium(Mg), Calcium(Ca). Some rocks that forms minerals consist high amount of iron. The amount of minerals and elements in every rock can very depending on shape and size.

Explanation:
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
