Moss Rocks! What are rocks, anyway?

Introduction

I love rocks. They’re beautiful, they’re useful and they’re everywhere. When you’re looking for a great rock garden furniture set, there are many different kinds to choose from. And some are more comfortable than others!

In the world of rocks, there are three kinds: igneous, metamorphic, and sedimentary.

  • [[Sedimentary rocks|http://www.ehow.com/info_8393330_sedimentary-rocks.html]]

Rocks can tell us about what has happened in the past.

Rocks are ancient, and they have a lot to tell us about the past.

They can tell us where the earth was before it was a planet—before it was anything at all. They can also tell us what happened once it became a planet: how it formed, how long ago that occurred, and whether or not there were any oceans then (there probably weren’t).

Rocks can also tell us about other planets in our solar system—especially ones with atmospheres like ours! If you’re interested in learning more about this topic, check out our article on How Do We Know About Other Planets?

Igneous rocks form when molten rock cools and hardens.

Igneous rock forms when molten rock cools and hardens. The cooling process can take millions of years and, depending on the type of igneous rock, it will form a different texture or pattern as it cools. Igneous rocks are the most common type of rock found on Earth; examples include granite, basalt, gabbro.

When magma cools far below the surface, it forms granite.

Granite is a hard, coarse-grained metamorphic rock that was originally formed deep below the surface of our planet. When magma cools far below the surface, it forms granite. This process is called intrusive cooling and happens because granite lacks water to keep its minerals in liquid form. In time, under great pressure, these minerals are squeezed together into new shapes that give granite its characteristic hardness and strength (making it resistant to weathering). Granite often contains feldspar crystals that show as white bands or veins running through otherwise gray or brown rocks.

Granite can also be formed when lava cools quickly near Earth’s surface where water can get at it; this type of formation is called extrusive cooling since it takes place above ground. Extrusive granites tend to be less dense than other types because they contain more air bubbles—these bubbles make them lighter than normal rocks!

Sedimentary rocks form from layers of mud and sand that have been compressed by other rocks for millions of years.

If you’re looking to build a rock garden, then you might be wondering what kind of rocks are good for your project. There are a few different types that can be used in gardens:

  • Sedimentary rocks formed from layers of mud and sand that have been compressed by other rocks for millions of years.
  • Igneous rocks formed as magma cools within the earth’s crust or mantle. They may also form when lava cools on earth’s surface (on land).
  • Metamorphic rocks that form from existing sedimentary or igneous rock through heat, pressure and chemical reactions at depth in the crust where temperatures exceed 250 degrees Celsius.

The third type of rock is metamorphic rock; it forms under extreme heat and pressure below the earth’s surface.

The third type of rock is metamorphic rock; it forms under extreme heat and pressure below the earth’s surface. Metamorphic rocks are used in construction, jewelry, furniture design, as well as art pieces.

“There are so many different types of rocks!

There are three main types of rocks. Igneous rocks formed from cooling liquid magma. Sedimentary rocks formed from compression and cementation at the surface of the earth, or by deposition. Metamorphic rocks are created by intense heat and pressure within the earth’s crust, which changes their mineral composition and structure.

All these types of rock tell us a lot about how our planet works, what it was like millions (or billions) of years ago when these rocks were formed!

Conclusion

Rocks are a great addition to any garden. They can add color, texture and beauty to any landscape. If you have never tried using rocks in your garden before, now is the time!
