What type of rock is found on the surface of the moon?
igneous rocks
The Moon’s surface is dominated by igneous rocks. The lunar highlands are formed of anorthosite, an igneous rock predominantly of calcium-rich plagioclase feldspar.
Which was the first to step onto the moon’s surface?
astronaut Neil Armstrong
At 10:56 p.m. EDT, American astronaut Neil Armstrong, 240,000 miles from Earth, speaks these words to more than a billion people listening at home: “That’s one small step for a man, one giant leap for mankind.” Stepping off the lunar landing module Eagle, Armstrong became the first human to walk on the surface of the …
What is the soil like layer on the moon’s surface called?
Share that the Moon and many planets and asteroids have a special type of soil on their surface, called regolith. Unlike the soil on Earth, the regolith on the Moon doesn’t have any organic materials: no seeds, roots, or bacteria.
What are the three types of rocks found on the Moon and where are they found?
1 Answer
- Basalt: The Mare Rock. Black volcanic basalts are found on 26% of the Moon’s near side (and 2% of the Moon’s far side).
- Breccia: Shocked Rock.
- Highland Rock: Anorthosite.
- Regolith Soil / Surface Layer.
What ores are on the Moon?

|---|---|
| Plagioclase feldspar | Calcium (Ca) Aluminium (Al) Silicon (Si) Oxygen (O) |
| Pyroxene | Iron (Fe), Magnesium (Mg) Calcium (Ca) Silicon (Si) Oxygen (O) |

When Neil Armstrong died?

Neil Armstrong/Date of death
Did Michael Collins walk on the moon?
He didn’t walk on the moon, but Michael Collins was as much a hero as those who did. His communication with NASA would be blocked, as would his contact with crewmates, Neil Armstrong and Buzz Aldrin — the first humans to walk on the moon.
What is the difference between the soil on the Moon and on the earth surface?
There are two profound differences in the chemistry of lunar regolith and dirt from terrestrial materials. The first is that the Moon is very dry. The second difference is that lunar regolith and crust are chemically reduced, rather than being significantly oxidized like the Earth’s crust.
What name is given to the layer of fine powder and rock fragments that cover the lunar surface?
The surface of the Moon is covered with a fine powdery material that scientists refer to it as “lunar regolith”. Nearly the entire lunar surface is covered with regolith, and bedrock is only visible on the walls of very steep craters.
What happens to the rock on the lunar surface?
Each cratering event, large or small, breaks up the rock of the lunar surface and scatters the fragments. Ultimately, billions of years of impacts have reduced much of the surface layer to particles about the size of dust or sand.
What kind of dust is on the surface of the Moon?
The dark basaltic dust of the lunar maria was kicked up by every astronaut footstep, and thus eventually worked its way into all of the astronauts’ equipment. The upper layers of the surface are porous, consisting of loosely packed dust into which their boots sank several centimeters (Figure 5).
What kind of rocks are in the highlands of the Moon?
The highlands consist of the ancient lunar surface rock, anorthosite, and materials thrown out during the creation of the impact basins. Relatively young basins are shown in light colors; the oldest basins are in dark colors.
How long has the rock been on the Moon?
This date corresponds to the formation of a large lunar impact basin from which the rock was thrown. Other studies indicate that the rock lay exposed on the lunar surface for 8.6 million years after it was moved again by the formation of Spook crater.
