Answer: B. Original Continuity
Explanation:
Original continuity is the concept that sediments are deposited horizontally at the original point of formation. This lateral deposit continues, layer by layer unless the sediments are interrupted by a barrier.
The two rocks on the opposite sides of the canyon were likely one body of rock due to their similar lithology and fossil content. It is likely that the canyon formed due to erosion over time, thereby creating a barrier between the rocks.
Process by which new rock is made from old rock; rock cycle
The rock cycle is a recycling process by which igneous, metamorphic, and sedimentary rocks are produced, converted from one form to another and destroyed. The rock cycle is a continuous process that has been occurring throughout the history of the earth. The major processes of the rock cycle include sedimentation, crystallization, metamorphism and erosion.
The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.
Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.
1) prevailing westerly winds
2)the North Atlantic Drift ocean current
ႊ့These two moderates much of the air temperature over Northwestern Europe.
Hope this helps!
I believe C is the correct answer; parent material is rich in nutrients for plants, and decomposed plant litter is also known as decaying organic material. Hope this helps! :)
