Rocks and Minerals
Rock Cycle and more....

A rock is a naturally occurring solid made up of one or more minerals that have been fused together. Rocks can be found in many different shapes, sizes, and colors, and can be found all over the Earth's surface.

​

What is a rock?

A mineral is a solid, naturally occurring substance found on Earth that is not made by plants or animals, and has a specific crystal structure, meaning its atoms are arranged in a repeating pattern, like tiny building blocks making up the mineral; think of it like a tiny piece of a rock with a unique shape!.

​

What is a mineral?

Formed when particles like sand, silt, dead plants, and animal skeletons settle out of water or air, or when minerals precipitate out of water. These particles accumulate in layers.

Sedimentary

​Formed when existing rocks are changed by heat, pressure, or reactive fluids. For example, water can dissolve minerals in old rock or carry new minerals into it, or magma's heat can change old rock. Marble and slate are examples of metamorphic rock. 

Metamorphic

​Formed when magma or lava cools and solidifies. Magma is a molten mixture of minerals, gases, and steam that rises from deep within the Earth. When magma reaches the surface, it's called lava. Granite and basalt are examples of igneous rock. Replace this with your body text. All provided templates can be reused multiple times.

The Rock Cycle

The "rock cycle" is a geological process that describes how the three main rock types - igneous, metamorphic, and sedimentary - transform from one type to another over time, driven by factors like heat, pressure, weathering, erosion, and plate tectonics, essentially illustrating how rocks are continuously formed, broken down, and reformed in a cyclical manner across Earth's crust.

Multiple Choice

What is the correct part of the Rock Cycle for #1?

(Key Words: Magma, Volcanic Eruption, Sediment, Sedimentary Rock, Igneous Rock, Metamorphic Rock)

• Magma

• Volcanic Eruption

• Sediment

• Metamorphic Rock

Multiple Choice

What is the correct part of the Rock Cycle for #5?

(Key Words: Magma, Volcanic Eruption, Sediment, Sedimentary Rock, Igneous Rock, Metamorphic Rock)

• Magma

• Volcanic Eruption

• Sediment

• Metamorphic Rock

Multiple Choice

What is the correct part of the Rock Cycle for #3?

(Key Words: Magma, Volcanic Eruption, Sediment, Sedimentary Rock, Igneous Rock, Metamorphic Rock)

• Magma

• Volcanic Eruption

• Sediment

• Metamorphic Rock

Example of the rock cycle:

• An igneous rock exposed at the surface can weather and erode, creating sediments that are transported and deposited to form a sedimentary rock. 

• If this sedimentary rock is buried deep within the Earth and subjected to high heat and pressure, it can transform into a metamorphic rock. 

• If the metamorphic rock is further heated to its melting point, it can become magma, which when cooled, forms a new igneous rock, completing the cycle.

Here are some ways to identify rocks:

Examine in person

• The best way to identify a rock is to examine it in person from all angles. You can take it to a local source, such as a natural science museum, college, or rock shop.

Look at the rock's texture

• Different types of rocks have different textures

Check the rock's hardness

• The hardness of a rock can indicate what minerals it contains.

Rock Identification.

​These rocks are hardened sediment with sandy or clay-like layers. They are usually brown to gray and may have fossils and water or wind marks.

Types of Rocks Include:
Bituminous Coal, Conglomerate, Limestone (Chemical), Limestone (Fossil), Sandstone, Shale

Sedimentary Rocks

These rocks are tough and frozen melts with little texture or layering. They are usually made up of black, white, and/or gray minerals. 

Types of Rocks Include:
Basalt, obsidian, granite, pumice, scoria

These rocks are tough and have straight or curved layers of light and dark minerals. They come in various colors and often contain glittery mica.

Types of Rocks Include:
Gneiss, Phyllite, Marble, quartzite, schist, slate

To identify minerals, geologists primarily use their physical properties like color, streak, luster, hardness, crystal form, cleavage, fracture, and specific gravity.

Streak:

The color of a mineral when scratched on a ceramic streak plate, which can be more consistent than the mineral's overall color. 
Luster:

How light reflects off the mineral surface, described as glassy, pearly, metallic, etc. 
Cleavage:

The tendency of a mineral to break along smooth, flat planes due to its crystal structure .
Hardness:

Measured on the Mohs scale, indicating how easily a mineral can be scratched by other materials.
