im not sure of the answer but i know that it is not B. but my guess would be C.
Answer:
5.19 Miles deep
Explanation:
To solve for this, divide the total amount of lava pumped within the duration of time by the land area of Indiana.
that is;
Depth of Indiana = 186,000/35867
Depth of Indiana = 5.19 miles
Answer:
A. Crests and troughs that remain stationary although the air forms them is moving rapidly.
Explanation:
The standing waves are a phenomenon that is a result of the interference of two wavelengths. The air over the mountain ranges is of high intensity as a result of temperature elevation. Fast movements of air currents produce scrambled ripples, as a result, the pattern of air crest and troughs remains static.
Answer:
D. it is part of a rift valley
Explanation:
Africa is believed to split in the future. There is still no consensus about how much will be needed for that, but it varies anywhere from 10 million years to 50 million years. There are several evidence that suggest to the geologists that this is happening, with the biggest one being the rift valley across the eastern portion of Africa.
The rift valley in Africa is actually a divergent boundary between the Nubian and Somali tectonic plates. The Somali plate moves eastward toward the Indian Ocean, thus separating itself from the larger Nubian plate.
The gap is becoming larger and larger every year, though for full separation of these two plates several millions of years will need to pass. Once the gap becomes wide enough and deep enough, the ocean water will fill it, thus making a natural barrier between the two plates, and thus creating a new separate continent.
