The base of the pennant is 12 feet shorter than the height......A = (1/2) * b * h
80 = (1/2) * (h - 12) * h
160 = h^2 - 12h
12/2 = 6
6^2 = 36
h^2 - 12h + 36 = 160 + 36
(h - 6)^2 = 196
h - 6 = 14
h = 20
b = 8
Answer:
The limestone found at the top of Mount Everest was formed in an ocean
Explanation:
The Himalayan Mountain Range, thus its highest peak Mount Everest as well, have been formed as a result of the collision between the Indian and Eurasian tectonic plates. The Indian plate, once it separated from Gondwanaland, started to move toward Eurasia. As it was getting closer, the plates started to push against each other. Since the boundary has been in the ocean, the ocean floor started to lift up first because of the immense pressure. As the plates continued to push against each other, the surrounding area was gradually pushed up, so what was once an ocean floor and lowlands was slowly becoming a mountain range. This resulted in limestone rocks that were formed in the ocean to be moved up for several kilometers and to become part of the highest mountain range in the world, providing us with another good proof of the continental drift theory.
Answer:
<u>South America, Central America, and the Cascade Volcanoes are an example of this type of subduction. Japan, Indonesia, and the Aleutian Islands are examples of this type of subduction</u>
Explanation:
- Subduction is a process of destruction of the old lithospheric plate at the construction of a new plate through the divergent boundary of the mid-oceanic ridge.
- For subduction to take place the plate or slab need to pass through a trench or subduction zone and can occur through the collision of oceanic crust and the collision of continental and oceanic crust which one is lighter goes under and hence volcanic and mountains are formed as a surface feature.
- Evert plate is moving at a well-defined rate of subduction either in east or west direction as the seafloor continues to spread.
Most of them came from central africa and west africa.
