It also makes up about 5% of the moon’s total mass. Iron is a highly abundant element, making up about 5.6% of the universe’s total mass. On Earth, iron is the fourth most abundant element and makes up about 5% of the Earth’s crust.

It is a key component of the Earth’s magnetic field and is also found in living organisms. Iron is a very strong element and has been used by humans for centuries to create tools, weapons, and other objects. When it comes to moon rocks, iron is essential to providing the rocks with their unique properties and characteristics.


Magnesium is an essential element that makes up a moon rock. It helps strengthen the whole structure and can provide a supporting frame for the other elements.

Magnesium is also abundant on the lunar surface, so it is an easy element to find in a moon rock. It has a high melting point, so it can withstand the hot temperatures in space.

This makes it a great choice to be part of a moon rock. Magnesium has many uses beyond moon rocks. It is an important ingredient in fertilizers and can also be used to make alloys and other metals.

It is also used in batteries and even in the medical field. So when you think about what makes up a moon rock, remember to consider magnesium and all the other elements, too.


Calcium is a common element found in moon rocks. It’s important for humans because it helps to maintain healthy bones and teeth. Eating foods that are rich in calcium, like dairy products, leafy greens, or nuts, can help your body get the daily recommended amount of calcium.

Calcium is also found in many of the supplements that are available these days. It’s interesting to note that calcium is also very abundant on the moon’s surface.

In fact, it’s estimated that the moon’s surface contains as much as three times the amount of calcium as Earth!

That’s why moon rocks make great samples for research and help us to learn more about the moon and its composition. When studying moon rocks, it’s important to consider the calcium content. The calcium in the samples will help give researchers an insight into the composition of the moon’s surface.

By studying the calcium content, researchers can gain a better understanding of the moon’s composition and the environment it exists in. It’s important to remember that calcium is an important component of moon rocks and can help in our exploration of the moon!


Aluminum is an important element in moon rocks. It is a very light and strong metal that is used in many products all around the world. It is not only found in moon rocks, but also in other terrestrial rocks.

Aluminum is the third most abundant element on the moon and the sixth most abundant element on Earth. It is highly reactive and forms compounds with other elements in the form of oxides, hydroxides and silicates.

Aluminum is essential for the structure of rocks and for the formation of soil and other geological materials. It also plays an important role in creating and maintaining the moon’s atmosphere.
