20 POINTS PLUS BRAINLIEST The diagram below shows different positions of Earth and Mars around the sun. Diagram shows the sun at
the left hand focus of Earth's elliptical orbit. Two positions of Earth are shown on the elliptical orbit. At Position A, Earth is closest to the sun. At position B, Earth is farther away from the sun. The elliptical orbit of Mars is shown around Earth's orbit. Two positions of Mars are shown on its orbit. At Position A, Mars is closest to the sun. At position B, Mars is farther away from the sun. Based on the diagram, which of these statements is correct? The orbital speeds of Earth and Mars are greater in position B than in position A. The orbital speeds of Earth and Mars are greater in position A than in position B. The orbital period of Earth in position A is greater than the orbital period of Mars in position B. The orbital period of Earth in position B is greater than the orbital period of Mars in position B.
The lithosphere or the land sphere are the plates that are surface layers of the earth. And this lithosphere is made up of Silicon and Aluminium components. The Lithosphere is divided into upper and lower parts by the thick layers of sedimentary rocks.
It constitutes of hard, rigid and outer skins of earth. On lithosphere, the entire biosphere that's the life sphere is based. There are two types of lithosphere i.e oceanic and continental the oceanic has a <u>density of 2.9 grams, and crust on land has 2.7 grams</u>.
Composition Of oceanic lithosphere is of mafic and ultramafic. The asthenosphere is a layer that forms underneath this zone and is in liquid molten forms. This also divided into three zones the upper zone, transition zone, and lower zone.
Melting of rock mass takes place in this layer as it has a depth of 2900 km and the boundary is defined by stress zone that deforms easily and has elasticity. Most of the earthquake waves and lava plums come out of this zone. It's composed of heavier metals like Iron and Aluminium, nickel, etc.
The presence of mustones by curiosity rover indicates chances of ancient life.
Explanation:
The Yellowknife bay is a geologic formation of the Gale crater on the planet Mars and NASA named the rover as a curiosity. Its primary goal was to assess the potential habitability and whether the mars are capable to support life.
The presence of the mudstones in the geologic depression area on mars leads to its name as Yellowknife i.e the capital of the northwest territory of Canada.
The findings of the mudstone from the stepped bedded stata indicate the clay minerals that show the presence of water and claims that an ancient creator was found on in this region and these indicators of a potential mafic source of origin of deposition.
