A. it is closer to the earth. Medium. Unlike on Earth, there is no erosion by wind or water on the moon because it has no atmosphere and all the water on the surface is frozen as ice. Because there is no atmosphere on the Moon, the temperatures there are very hot during the day (100°C) and very cold at night (-173°C). According to NASA research, the moon is slowly losing heat, which causes its surface to shrivel up like a grape turning into a raisin. So footprints of the astronauts also remains for the millions of year as it is. it is sometimes thin). The atmosphere of the moon is considered to be surrounded by a vacuum, but there are atomic particles from the moon’s surface create a “lunar atmosphere” for scientific purposes. Because the moon has no atmosphere, its in the vacuum of space. Maybe. The escape speed on the moon is much smaller than that on the earth. There is not life on moon because there is no. When these photos were taken, it was full daylight on the Moon. Explain why (a) there is no atmosphere on moon (b) there is fall in temperature with altitude . It has a black sky, has almost no atmosphere due to its weak gravity. No. Its gravity pulls slightly on the Earth. At first it seems possible. View Chapter 10 Homework .pdf from PHYS 1404 at Tarrant County College. Likelihood of feeling lonesome and desolate: 92%. (b) it is too for from the sun and has very low pressure in its outer surface. 1 2 % of the earth's mass and thus her escape velocity is only 2. the gravitational pull is too weak.

If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. First, the moon has far less mass than a planet due to its small size. Sound cannot travel on the moon because of the lack of an atmosphere. This is not to say that life cannot survive on the moon, as many science fiction fans are hoping. all moons have no atmosphere, and it has NOTHING to do with the water because mars has an atmosphere too, and so does venus and all the other planets (though with some it seems that no atmosphere exists. By definition, logic won’t work. There is also no “daytime” or “nighttime” because of the lack of an atmosphere. also, it is completely solid, whereas the earth has a core. (c) escape velocity of gas molecules is greater than their root mean square velocity. There is not life on moon because there is no. So footprints of the astronauts also remains for the millions of year as it is. 1 decade ago. As a result, any gases released on the moon, if there are any, would be ripped away quickly by the solar wind. This reduces the amount of gravity on the moon. On the Moon, based on the history of its formation, its lack of an atmosphere and its classification as a “dead” rock, there is no feasible way for life to develop and prosper on the moon. Solution Show Solution. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. There is no life on the moon, and therefore none of these gasses. 2 1. the gravitational pull is too weak. Sol: The escape velocity of the moon is very small and so all the gaseous molecules that might have existed at the time of its creation have escaped from its surface because the rms speed of molecules exceeds the escape velocity of the moon. Therefore, the value of escape speed on the surface of the moon is small (only 2.5kms-12.5kms-1).The molecules of the atmospheric gases on the surface of the moon have thermal speeds greater than the escape speed. A) Because it is so far away. There are two reasons. There are probably regions of Think of the Sun as a light bulb, and the Moon as a mirror, reflecting light from the light bulb. But that is not possible, because there is no atmosphere on the moon. C. it gets light from the sun. In our everyday lives, that’s usually air or water (where the faster speed of sound robs us of our spatial locating sense). There is no atmosphere on the moon, because (a) escape velocity of gas molecules is less than their root mean square velocity (b) it is closer to the earth and also it has the inactive inert gases in it Our atmosphere takes sunlight, and it’s *scattered*- refracted and absorbed, and the color absorbed the least is blue… that’s what we see when we look up in the daytime. The blaze quickly engulfed the cabin, aided by an atmosphere of 100 per cent oxygen and highly flammable materials. The Moon does not have a strong enough gravitational field to support an atmosphere. Compared to the Earth, the moon is about 1/4th the size. there is no atmosphere on the moon. B) Because it has only 13 days of daylight. Log in. Log in. (b) it is too for from the sun and has very low pressure in its outer surface.
