The variation on the Moon is much less because the 3 major minerals in lunar rocks, plagioclase feldspar (usually anorthite), pyroxene, and olivine, all have about the same SiO2 concentration.
What are the most abundant elements on the Moon?
Elemental composition
Elements known to be present on the lunar surface include, among others, oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminium (Al), manganese (Mn) and titanium (Ti). Among the more abundant are oxygen, iron and silicon. The oxygen content is estimated at 45% (by weight).
What are 3 important surface features of the Moon?
There are three main surface features of the Moon: highlands, maria, and craters. The highlands, which are old mountains made of igneous rocks, make up about 83 percent of the Moon’s surface. Maria are the dark areas that we see when we look at the Moon from Earth. These are old lava flows that cooled on the surface.
What elements are in moon rocks?
Mineralogically, most Moon rocks are pretty simple. Common lunar minerals include silicates, made up of silicon and other elements like calcium, aluminum, oxygen, magnesium, and iron.
What are the 3 types of moon rocks?
Types of rocks on the Moon: basalt, anorthosite, breccia, and “soil” (regolith).
What are the top 3 most abundant elements on earth?
Oxygen, silicon, iron and aluminum are the most abundant elements in the Earth’s crust, accounting for 88.1% of its mass.
What elements are only found on the Moon?
Elements known to be present on the lunar surface include, among others, hydrogen (H), oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminium (Al), manganese (Mn) and titanium (Ti).

What are the 3 surfaces of the Moon?
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 does the Moon surface contain?
The average composition of the lunar surface by weight is roughly 43% oxygen, 20% silicon, 19% magnesium, 10% iron, 3% calcium, 3% aluminum, 0.42% chromium, 0.18% titanium and 0.12% manganese. Orbiting spacecraft have found traces of water on the lunar surface that may have originated from deep underground.
What was found on the surface of the Moon?
Molecular water, H2O, was found in Clavius Crater, one of the largest craters visible from Earth in the Moon’s southern hemisphere. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.
What minerals are abundant on the Moon?
The Moon is dominantly composed of silicate minerals. Typically, plagioclase is by far the most abundant and there commonly are substantial amounts of pyroxenes and olivines. Together, these three mineral groups usually, but not always, make up >95% of the crystalline material in the rock and the regolith.
What rare elements are on the Moon?
And the Moon may also have ores of rare, incompatible, lithophile elements such as beryllium, lithium, zirconium, niobium, tantalum, and so forth.
What are the top 3 elements?
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%. Oxygen is the third-most abundant element in the universe.
What are the 3 most important elements?
Scientists believe that about 25 of the known elements are essential to life. Just four of these – carbon (C), oxygen (O), hydrogen (H) and nitrogen (N) – make up about 96% of the human body. 25 elements are known to be essential to life.
What 3 elements are most abundant in Earth’s modern atmosphere?
The most abundant naturally occurring gas is nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas argon (Ar) is the third most abundant gas at 0.93%.
What are 3 Moon facts?
Facts About The Moon
- The Moon is Earth’s only natural satellite and the fifth largest moon in the solar system.
- The Moon’s presence helps stabilize our planet’s wobble and moderate our climate.
- The Moon’s distance from Earth is about 240,000 miles (385,000km).
- The Moon has a very thin atmosphere called an exosphere.
What is the most common feature on the surface of the moon?
The Moon’s surface is characterized by highlands and lowlands, mountains, and most notably, craters (bowl-shaped cavities of meteoric origin). These craters are often marked by secondary craters and by rays from ejecta — ejected matter from the meteor’s impact.
Does the moon have 3 layers?
Just like Earth, the Moon can be divided into the crust, mantle and core. At its very centre, the Moon has a solid iron core with a temperature of between 1,327°C and 1427°C.
What kind of rock is on the surface of the Moon?
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.
What are the four main surface features of the Moon?
The Top Five Features To Find On The Full Moon
- 1.) The lunar maria.
- 2.) Montes Apenninus.
- 3.) Tycho crater.
- 4.) Copernicus crater.
- 5.) Oceanus Procellarum.
Which metal is most abundant in the Moon?
The most abundant element found on the Moon is oxygen (about nearly 42%) among others. Iron, Silicon, Magnesium, Calcium, Titanium, etc are the elements found on the surface of the Moon.
