Answer:
because it shows that you use correct language in class
Explanation:
Answer:
1. Applying <u>the principle of original horizontality</u> -indicates that layers were repositioned from a flat-lying orientation.
2. Magma intrudes into layers of sedimentary rock and displaces them. We can deduce that the intruded magma that crystallizes is younger than the surrounding sedimentary layers by applying <u>the principle of crosscutting relationships</u>.
3. While visiting the Grand Canyon, you are amazed by the depth of layers of sedimentary rock before you, <u>the law of superposition</u>-- is evident here where progressively younger layers have formed over time and are stacked upon each other.
4. A fault cuts through layers of limestone, sandstone, and conglomerate. The surrounding layers must be <u>older</u> than the fault.
5. A mass of granite has inclusions of surrounding sandstone. The sandstone and surrounding layers show evidence of uplift over time. The granite must be <u>younger</u> than the sand deposits.
The answer is: the 1906 San Francisco earthquake.
From an examination of the displacement of the ground surface which accompanied the 1906 earthquake, Henry Fielding Reid, Professor of Geology at Johns Hopkins University, concluded that the earthquake must have involved an "elastic rebound" of previously stored elastic stress.
The elastic rebound theory is an explanation for how energy is spread during earthquakes. As rocks on opposite sides of a fault are subjected to force and shift, they accumulate energy and slowly deform until their internal strength is exceeded.
Colonialism made African colonies dependent by introducing a mono- cultural economy for the territories. It also dehumanized African labor force and traders. It forced Africans to work in colonial plantations at very low wages and displaced them from their lands.
Answer:
Slowly and Deep underground
Explanation:
As heavy warm , molten metal and rocks crystallizes and strengthens, Igneous rocks are formed. Extrusive rocks explode on the ground, when they rapidly cool to quickly form minerals and rocks.
