If there's no atmosphere on the moon why are all craters direct hits Why not are some glancing blows Why no trenches why all craters?
(Question is a bit murky, so I'll answer to the best of my abilities.)
There is no atmosphere so any hits from meteorites do not erode, and since there is no water, and no wind or other erosion sources, trenches and valleys are not created. The moon has some gravitational pull so it attracts these small space rocks to hit it, not just fly by.
Additionally, the main reason why there appears to be no glancing blows or trenches is because meteoroids colliding with the Moon generate "a shock wave in the lunar surface that spreads out from the point of impact. Such a shock wave produces a circular crater no matter what direction the meteoroid was moving." - From 'Universe - The Solar System' 3rd Edition.

Why do asteroids affect the surface of the Earth and the Moon differently?
Asteroids can affect the Earth's surface more due to its thicker atmosphere, which causes asteroids to experience greater resistance and breakup before impact. On the Moon, with no atmosphere to slow down or break up asteroids, impacts are more direct and create craters that can remain preserved for longer periods of time.
Does eris have volcanoes?
Yes, Eris is a dwarf planet located in the outer solar system, and it is believed to have a rocky composition similar to Pluto. While there isn't direct evidence of volcanoes on Eris, its surface is believed to be made of ice and rock, so it is possible that there may have been cryovolcanic activity in the past.
Does Mercury have polar ice caps?
No, however there is some indirect evidence of Ice on the bottom of craters on its north pole. It was discovered via radar observations. Ice is one of the few materials that are very radar reflective when frozen, and it was discovered that Mercury has very reflective matter in its northern craters.
What prevented the Moon from maintaining any atmosphere with which it originally formed?
A lack of sufficient gravity. The gravity on the moon is so weak that the rays of the sun (the solar wind) completely blew away any atmosphere the moon may have had. The rest of the lunar atmosphere evaporated into space due to the high heat from the direct sunlight.
What are 3 ways the atmosphere moves energy?
Convection: Warm air rises and cool air sinks, creating vertical movement of energy. Conduction: Energy is transferred through direct contact between the atmosphere and Earth's surface. Radiation: Solar energy is absorbed by the atmosphere and re-emitted as infrared radiation.

What led to the construction and use of trenches in combat?
It was ground artillery wars that led to the construction and use of trenches in combat. These trenches provided military members with an adequate area to position themselves against opposing forces that took them out of the direct line of hand artillery.
What internal organs are in direct contact with the atmosphere?
The lungs are the only internal organs that are in direct contact with the atmosphere, as they exchange gases with the air to facilitate respiration.

Why it is cold above the atmosphere?
It is not necessarily cold above the atmosphere. In direct sunlight, it can be quite hot.
What is the most direct route for precipitation to return to the atmosphere?
The most direct route for precipitation to return to the atmosphere is through the process of evaporation. This occurs when water on the Earth's surface, such as oceans, lakes, and rivers, is heated by the sun and changes from liquid to vapor, rising into the atmosphere.
What is the impact of an earthquake on the Earth's atmosphere?
Earthquakes do not have a direct impact on the atmosphere. An earthquake only damages the Earth and structures on the Earth.
Where did World War 1 soldiers sleep?
Mostly on the ground, if they were in the trenches. They would scrape "funk holes" in the side of the trenches as some protection from the elements and shrapnel or, if they were lucky there would be a dugout - an underground tunnel that would be safe against all but a direct hit from a shell.
Why is the atmosphere is heated cheifly by radition from Earth's surface rather than by direct solar radiation?
The atmosphere is heated chiefly by radiation from Earth's surface because the Earth's surface absorbs solar energy and emits it as infrared radiation. This infrared radiation is then trapped by greenhouse gases in the atmosphere, causing the atmosphere to be heated. Direct solar radiation contributes to heating the Earth's surface, which in turn warms the atmosphere through convection and radiation.
How the atmosphere does to earth?
It contains the ozone layer,different gasses,and to prevent direct rays from the sun.

What would be a direct effect of increases in the amount of this gas?
One direct effect of increases in the amount of carbon dioxide in the atmosphere is global warming. This is due to carbon dioxide trapping heat in the Earth's atmosphere, leading to increased temperatures and causing changes in climate patterns.
