Types of Rocks: Lesson for Kids |

Types of Rocks. There are three types of rock on Earth: Igneous, sedimentary, and metamorphic.Some things on Earth are different because of the way they look or feel. Rocks come in all shapes ...

Sedimentary Rock Formation Explained

These types of rocks are formed on the Earth's surface, as well as underwater. Wherever sedimentation goes on, rocks are formed over time. The sediments that compose these rocks may be of organic, chemical, or mineral origin. Although, these rocks constitute only 5% of the total crust volume, they extensively cover most continental surfaces.

Stratification | geology | Britannica

Stratification in volcanic rocks differs in some respects from that in sedimentary rocks. Fragmental volcanic material becomes sorted in flight under the influence of gravity, particle size, and wind. Falling to the ground, it may form well-sorted layers. If it falls into lakes or the sea, it becomes layered like any other waterborne detrital ...

Types of Rocks | Science Video for Kids

Apr 06, 2016· Rocks are an example of a natural resource. There are three different types of rocks - Igneous, Sedimentary and Metamorphic rocks. Let's learn more about rocks in this video! #Education #Kids # ...

Metamorphic Rock Facts | Cool Kid Facts

Metamorphic Rocks For Kids. Rocks are made up of one or more minerals. Although different rocks can contain the same minerals, they are sorted into different types of rocks depending on how they were formed.. Metamorphic rocks form when existing rocks are exposed to heat and pressure deep within the Earth's surface. That's a pretty neat way of understanding different types of rocks!

Geology 101

Like the world's oldest blog, rock reveals millions of years of events and change. It shares how and when the earth's features, like mountains, oceans, or canyons were shaped. In a way, embedded fossils provide a selfie or picture of the environment at the time the rock was formed. Rock: rockin' the Earth for 4.55 billion years!

Geology Quiz: Earth And Rocks!

Jun 22, 2020· There are different types of rocks on the Earth's surface, and each has its distinct characteristics. In our previous classes, we go to learn more about rocks, how they are formed, and their benefit to the Earth's surface. Just how attentive were you? Take up the test below, and let's get an idea of what you remember on the topics of rocks and rock cycle.

Formation of the Grand Canyon | Kids Answers

In the lab, rock can be bent without cracking under intense heat and pressure, but the process changes the minerals and structure of the rock (this process is called metamorphosis). In the Grand Canyon, though, the bent or folded sedimentary layers show no evidence of metamorphosis over the claimed millions of years since the sedimentary layers ...

Limestone Facts for Kids

Limestone is a sedimentary rock, made up mostly of the mineral calcite, a form of calcium carbonate, CaCO 3.. The calcium carbonate is originally produced by living organisms. Later, some of it goes into solution in sea water. Limestone rocks include mainly organic remains and precipitated carbonate.. Limestone makes up about 10% of the total volume of all sedimentary rocks.

Metamorphic Rocks | National Geographic Society

Oct 10, 2019· Igneous rocks formed when liquid magma or lava—magma that has emerged onto the surface of the Earth—cooled and hardened. A metamorphic rock, on the other hand, began as a rock—either a sedimentary, igneous, or even a different sort of metamorphic rock. Then, due to various conditions within the Earth, the existing rock was changed into a ...

Sedimentary rocks

Sedimentary rocks are formed from the broken remains of other rocks that become joined together. The weight of the sediments on top squashes the sediments at the bottom. This is called compaction ...

Igneous rocks

Igneous rocks are formed from molten rock that has cooled and solidified. The inside of the Earth is very hot - hot enough to melt rocks. Molten (liquid) rock is called magma. When the magma cools ...

Properties of Igneous Rocks for Kids | Sciencing

The molten rock, or lava, has cooled to form igneous rocks. Mount Rushmore, where the Presidents' faces are carved in the mountainside, was chiseled out of granite, another igneous rock. Half Dome is an igneous rock formation in Yosemite National Park.


Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified – turned to rock. Sedimentary rocks can be formed in deserts, lakes, rivers and seas.

Exfoliation | geology | Britannica

The outer surface of exposed rock dries rapidly after wetting; but moisture that penetrates into minor crevices stays until some decay is started, and the resultant swelling causes flaking roughly parallel to the outer rock surface. A small-scale form of exfoliation, called spheroidal weathering, is restricted to boulder-sized rock material and ...

Sedimentary Rock Facts for Kids

Enjoy our sedimentary rock facts for kids. Find interesting information and a range of examples that help explain what sedimentary rocks are and what makes them different from other kinds of rocks. Sedimentary rocks are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans .

Igneous Rocks: Formation, Types and Examples | Earth Eclipse

Igneous rocks form from the cooling of magma - molten materials in the earth's crust. The terminology Igneous means fire or heat. In this sense, igneous rocks are formed when molten rock (magma) solidifies either underneath the earth crust to form plutonic (intrusive) igneous rocks or on the surface of the earth to form volcanic (extrusive) igneous rocks.

Types of Rocks Facts, Worksheets & Classification of Rocks ...

A rock is any naturally occurring solid mass or aggregate of minerals. It is categorized by the minerals included, its chemical composition, and how it is formed. Rocks are usually grouped into three main groups: igneous rocks, metamorphic rocks, and sedimentary rocks.
