What does the Moon lack that Earth has?

It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth’s (0.1654 g); Jupiter’s moon Io is the only satellite in the Solar System known to have a higher surface gravity and density.

How would the Earth be different without the Moon?

The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.

How would the absence of the Moon affect the food web?

Many predators, like owls and lions, rely on the cover of darkness with just a bit of moonlight to hunt effectively. With no moon, they would have trouble finding food. Because the moon is so close to us, the pull of its gravity impacts our planet.

What is one important way in which both the moon and Mercury are different from Earth?

After all, the two bodies have significant differences: unlike the moon, Mercury has a global magnetic field; its density is higher; there is an abundance of volatile elements such as sulfur; its surface contains much less iron, particularly in its crustal silicates — which indicates that the processes deep inside both …

Which landforms are found on the Moon and Earth?

While the craters, highlands and maria are the moon’s three main landforms, the moon’s surface has a number of other highly visible features. For example, some impact craters have bright rays that shoot outward from the center. Also, the moon has a number of rilles, which are long, thin tunnels or trenches.

What is the difference between surface of the Earth and surface of the Moon?

The surface area of the Moon is 37.9 million square kilometers. That sounds like a lot, but it’s actually smaller than the continent of Asia, which is only 44.4 million square km. The surface ares of the whole Earth is 510 million square km, so the area of the Moon compared to Earth is only 7.4\%.

What are the main features of the Moon’s surface?

Why is the Moon’s surface not weathered?

This is due to the fact that the Moon has no atmosphere or flowing water on it, and hence no natural weathering process. When the micro-meteoroids slammed into the surface and created all the particles, there was no process for wearing down its sharp edges.

Why is the atmosphere important to life on Earth?

Atmosphere Traps heat, shields the surface from harmful radiation, and provides chemicals needed for life, such as nitrogen and carbon dioxide. Small planets and moons have insufficient gravity to hold an atmosphere. The gas molecules escape to space, leaving the planet or moon without an insulating blanket or a protective shield.

Is there bedrock on the Moon?

Nearly the entire lunar surface is covered with regolith, and bedrock is only visible on the walls of very steep craters. Earth viewed from the Moon by the Apollo 11 spacecraft, across a sea of lunar soil. The Moon regolith was formed over billions of years by constant meteorite impacts on the surface of the Moon.

What factors make a planet habitable for humans?

Factors that make a Planet Habitable conditions. At about 125oC, protein and carbohydrate molecules and genetic material (e.g., DNA and RNA) start to break apart. Also, high temperatures quickly evaporate water. Surface: Only Earth’s surface is in this temperature range. Sub-surface: The interior of the
