Answer:
Sierra Madre Occidental
Explanation:
this mountain range takes up nearly 140,000 square miles of Mexico.
Answer:
speed of apparent on moon = 0.50847° per Hour
speed of apparent movement on Jupiter= 36.36° per Hour
Explanation:
given data
Sun appears to move = 15˝/hr
to find out
How many degrees per hour would the Sun appear to move if we at equator of the Moon and How many degrees per hour would the Sun appear to move if we at the equator on Jupiter
solution
we know that sun is stable it not move but earth is revolving around that sun but it appear sun rise
so movement of sun in sky 360° every day
and time taken = 24 hours
so as we have given
speed of the apparent movement=
°/Hour = 15 °/Hour
so
we have given Time taken by the sun to Moon's sky = 29.5 days = 29.5 × 24 = 708 hours
so
speed of apparent on moon = ![\frac{360}{708}](https://tex.z-dn.net/?f=%5Cfrac%7B360%7D%7B708%7D)
speed of apparent on moon = 0.50847° per Hour
and
we know Time taken by the sun to Jupiter = 9.9 hr
so
speed of apparent movement on Jupiter= ![\frac{360}{9.9}](https://tex.z-dn.net/?f=%5Cfrac%7B360%7D%7B9.9%7D)
speed of apparent movement on Jupiter= 36.36° per Hour
Answer:
b. crystallization above ground and crystallization below ground
Explanation:
The magma undergoes transition when it moves from the mantle layer toward the lithosphere. The reason for this is that the pressure and temperature drastically change. With other words, the magma starts to cool off as it comes toward the surface of the Earth. As the magma cools off it starts to crystallize, resulting in the formation of igneous rocks. When the magma comes out on the surface, known as lava in those cases, it cools of very quickly because the temperature and pressure are much lower. Because the cooling off occurs very quickly, the magma crystallizes quickly, so the crystals are small, and it forms extrusive igneous rocks. When the magma cools off underground, but still relatively close to the surface, the temperature and pressure are slightly bigger than those on the surface. Because of this, the magma cools off slower, thus it crystallizes slower. This results in the formation of larger crystals, and intrusive igneous rocks.
