Answer:
The astenosphere is located below the lithosphere
The mantle is composed of silicate material
Explanation:
The Earth has several different layers, and they can be presented in two different manners, depending on their chemical composition and their physical properties. According to the chemical composition the Earth has three layers, crust, mantle, and core, while in accordance to the physical properties it has five, lithosphere, astenosphere, mesosphere, outer core, and inner core.
The astenosphere is the second layer from the top, and it lies just below the lithosphere. It is also the upper part of the mantle. The mantle is a layer that is largely composed of silicate material, mostly silicate molten rock. It can easily be seen from the volcanic activities that this layer is composed of silicate material because the magma is rich in it, and the magma comes from this layer.
Answer:
It will be able to measure the distances of stars located across the Milky Way galaxy and outside it up to a distance of 50 Kiloparsec.
Explanation:
1 arcsecond is 1/parsec.
0.00002 arcsecond is 1/0.00002 parsec = 50,000 parsecs or 50 Kiloparsecs.
The shortest distance to the edge of the Milky Way is about 8 Kiloparsec and the farthest is about 24 Kiloparsec. So at this parallax angle, it can measure the distances of stars across the Milky Way galaxy. Any stars within a distance of 50 Kpc will be measured by GAIA. However, since the closest galaxy to the Milky Way is about 770 Kpc away, GAIA will be unable to measure any stars in another galaxy.
Answer:
Option (C)
Explanation:
The sharing of a convergent plate boundary between two continental plates results in the formation of a sandwich pattern, where the rocks at the edges of both the plates are crushed and crumbled and folded. Here the magma beneath the plates cannot rise up to the surface due to its high thickness, so it does not lead to the formation of volcanoes. For example, the Himalaya.
There is the possibility of occurring frequent landslides at the higher elevated mountainous areas due to the steeper slope of the mountains. It can also lead to the occurrence of flood, as there is the presence of plateaus that are formed at the top of the mountains that has the ability to trap water within them.
Thus, the correct answer is option (C).
The correct answer is - No.
Winnipeg, Canada, is not further away from the Equator than Moscow, Russia, in fact Moscow is the city that is further away from the Equator. Moscow is on a latitude of 55.7558° North, while Winnipeg is on a latitude of 49.8951° North, thus putting Moscow by 5.8607° further away from the Equator than Winnipeg is.
