What are the GREY areas on the moon?

Those spots are called maria, from the Latin word for sea, because early astronomers mistakenly thought they were lunar seas (they’re actually volcanic plains). The smooth and dark maria cover 17 percent of the surface of the moon. Almost all of them are visible from Earth.

What are the gray spots on the Moon?

Eyeballing the Moon



These gray patches are solidified volcanic lava flows. In the Moon’s youth, its interior was still molten, and magma would erupt onto its surface. These dark areas formed when massive asteroid or meteorite impacts on the Moon’s surface created basins.

What is the shaded part of the Moon?

The near side of the moon has light areas referred to as Lunar Highlands and dark areas called Maria. The maria are lower in altitude than the highlands and filled with dark solidified lava from when the moon was volcanically active.

Are the GREY spots on the Moon craters?

The dark spots on the lunar surface are actually craters of varying sizes that formed due to collisions from celestial bodies, such as comets, meteorites and asteroids in the past, which left large, excavated holes after the impact.

Why are footprints on the Moon still there?

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. Also, there is no volcanic activity on the moon to change the lunar surface features. Nothing gets washed away, and nothing gets folded back inside.

Are there seas on the Moon?

The maria, or ‘seas’, were named by early astronomers who mistook them for actual oceans on the Moon, but of course today we know that no such large bodies of liquid water exist on the lunar surface.

What are maria on the Moon?

In actuality, maria are huge basins containing lava flows marked by craters, ridges, faults, and straight and meandering valleys called rilles and are devoid of water. There are about 20 major areas of this type, most of them—including the largest ones—located on the side of the Moon that always faces Earth.

What is regolith on the Moon?

On the Moon, regolith occurs as a mixture of powdery dust and broken rock. Lunar regolith is formed by the impact of meteorites on the body’s surface. The force of the collision melts some of the impacted regolith to form objects known as agglutinates and heaves debris (ejecta) outward from the point of impact.

How many oceans are on the Moon?

The traditional nomenclature for the Moon also includes one oceanus (ocean), as well as features with the names lacus (‘lake’), palus (‘marsh’), and sinus (‘bay’). The last three are smaller than maria, but have the same nature and characteristics.

What are 5 seas on the Moon?

Section 1: The lunar seas

• Mare Vaporum:

Are there lakes on the Moon?

Of course, we’re not talking about a big lake or stream here. In reality, the data shows the equivalent of a 12-ounce-bottle of water trapped in the soil. The fact that this water is on the sunny side of the Moon is remarkable because, without a thick atmosphere, there’s nothing to keep it on the planet.

Does the Moon rotate?

It made so much sense now! The moon does rotate on its axis. One rotation takes nearly as much time as one revolution around Earth. If the moon were to rotate quickly (several times each month) or not rotate at all, Earth would be exposed to all sides of the moon (i.e. multiple different views).

Does sun rotate?

The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun’s rotation axis is tilted by about 7.25 degrees from the axis of the Earth’s orbit so we see more of the Sun’s north pole in September of each year and more of its south pole in March.

What is on Dark Side of the Moon?

Video quote: The monsterous sphere that is the moon blocks the signals between Earth and any along the other side to get around the problem you and your team placed a satellite.

What will happen to your weight when you go to the Moon?

The moon’s gravitation force is determined by the mass and the size of the moon. Since the moon has significantly less mass than the Earth, it will not pull objects toward itself at the strength that Earth will. This means that if you went to the moon you would weigh less, even though your mass stays the same!

What would happen if we had no gravity?

Humans and other objects will become weightless without gravity. If we have no gravity force, the atmosphere would disappear into space, the moon would collide with the earth, the earth would stop rotating, we would all feel weightless, the earth would collide with the sun, and as a consequence. We would all perish.

Why is weight of man reduced on moon?

Mass of the moon is less than the Earth, therefore, the force of attraction is less. Mass of the moon is more than the Earth, therefore, the force of attraction is more.

Is it true that you would weigh less if you were standing on the moon?

You weigh less when you stand on the Moon, because the force of attraction is less. If you weigh 150 lb on the Earth, you would weigh only 25 lb on the Moon. You haven’t changed (you are made up of the same atoms), but the force exerted on you is different.

How do birds fly if gravity is pulling them to the ground?

Flight in birds and planes works in a similar way; both have to generate lift to overcome gravity and thrust to move forward in the air – but birds don’t have engines to provide thrust! Instead birds flap their wings, which pushes a bubble of air (called a vortex) behind them and downwards.

How high can you jump on the Moon?

The Moon’s gravity at the surface is only 17 percent that of Earth’s. Using the same force of a jump on Earth, you could rise about 3 metres (10 feet) off the ground and stay in the air for about 4 seconds.

Does the Moon have gravity kids?

The Moon also exerts its force of gravity; since it’s smaller and lighter than Earth, if we could weigh ourselves on it we would discover we weigh around a sixth of our weight on Earth. One could ask why the Moon doesn’t fall on Earth as an apple from the tree.

Can you jump off the Moon?

Although you can jump very high on the moon, you’ll be happy to know that there’s no need to worry about jumping all the way off into space. In fact, you’d need to be going very fast – more than 2 kilometres per second – to escape from the moon’s surface.

How high could you jump on Mars?

Well, Mars is smaller than Earth, and its gravity is only 37 percent as strong as Earth’s. That means you could jump about four feet up off the ground. This is better than Earth (1.5 feet), Mercury (three feet), and Venus (1.5 feet), but the Moon (10 feet) is still better!

What is the temperature on the Moon?

When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C). There are also no seasons on the Moon. We have seasons because the Earth tilts on an axis at roughly 23.5 degrees.

Do astronauts sweat in space?

Space station astronauts exercise two hours every day to counter the muscle- and bone-withering effects of weightlessness, quickly leaving their workout clothes sweaty, smelly and stiff. CAPE CANAVERAL: How do astronauts do laundry in space?

Is the flag still in the Moon?

Images taken by a Nasa spacecraft show that the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing. The photos from Lunar Reconaissance Orbiter (LRO) show the flags are still casting shadows – except the one planted during the Apollo 11 mission.
