AT&T; LTE 2:25 PM 40%ED. New content added: Why are there fewer la 4) Why are the cores of the terrestrial worlds mostly metal? Consequently, what two metals are the predominant metals in Earth's core? 5) What chemical/physical/psychological reason causes Mars to appear reddish in color? 6) What is important about the ozone of Earth? 7) Supposing Earth and Venus outgassed the same amount of the greenhouse gas carbon dioxide, what stops Earth from having a runaway greenhouse like Venus? Explain in detail

Explanation / Answer

Ans.

4. The core is where the majority of a planet's metals migrate; the core is entirely metal, mostly iron. Althought its core is smaller than Mercury's by proportion, Earth's core is still absolutely larger than all of Mercury. Earth's core is the largest out of the four terrestrial planets. Hence, terrestrial planet is a celestial body that is composed primarily of silicate rocks or metals and has a solid surface. This distinguishes them from gas giants, which are primarily composed of gases like hydrogen and helium, water, and some heavier elements in various state terrestrial planets most metal-rich. A terrestrial planet, telluric planet, that is composed primarily of silicate rocks or metals. Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars. The terms "terrestrial planet" used. All terrestrial planets have approximately the same type of structure: a central metallic core composed of mostly iron, with a surrounding silicate mantle. Such planets have common surface features, which include canyons, craters, mountains, volcanoes, and other similar structures, depending on the presence of water and tectonic activity.

Outer core is liquidus.The Inner Core is a solid ball composed of an element named NiFe. Ni for Nickel and Fe for Ferrus also known as Iron.

5. Mars is covered in lots of iron oxide. Because its soil has iron oxide or rust particles in it. That's reason for reddish appearance of Mars.

6. We know Stratospheric ozone layer absorbs ultraviolet light (UV) these lights emitted by the sun. If the solar UV light were able to penetrate the stratosphere and troposphere and reach the earth’s surface, it would seriously damage our ecosystem. For example, ultraviolet light kills microbes, bacteria, and fungi.These microscopic forms of life play a key role in plants being able to process and absorb nutrients in the soil.Along these it's responsible for skin cancer in human being and several other diseases.

7. Venus is the hottest planet in the Solar System. With a global temperature of 735 Kelvin.carbon dioxide is a greenhouse gas. Various wavelengths can pass through this invisible gas, but it’s very effective at trapping heat. Light from the Sun strikes the ground of Venus, and warms it up. Water vapor is an even more powerful greenhouse gas than carbon dioxide and this caused temperatures to rise even more. Then the surface of Venus got so hot that the carbon trapped in rocks sublimated into the atmosphere and mixed with oxygen to form even more carbon dioxide.The atmosphere of Venus is 90 times more dense than that on Earth and it is made of 96.5% of CO2 and a 3% of nitrogen. This means that both planets have the same amount of Nitrogen on their atmospheres. Surprinsingly the CO2 on Earth is stored on calcite type rocks and if we would convert the CO2 on these rocks into atmospheric CO2 it would amount to the same amount of CO2 that there is on Venus' atmosphere.
Because of the denser atmosphere and the chemical composition Venus experiences an inmense green-house effect that raises the temperature over the surface to more than 470ºC.
