1- Obtain, Evaluate, and Communicate Information
What is the process called that breaks rocks down into smaller pieces?
Weathering, through physical or chemical means.
What is a mineral?
A naturally occurring, inorganic solid with a specific chemical composition and crystal structure.
What are the three main types of rocks?
Igneous, sedimentary, and metamorphic.
What is the rock cycle?
The continuous process where rocks are formed, broken down, and reformed over time.
What is hardness?
A measure of how resistant a mineral is to scratching.
How can you determine the age of a rock?
By using methods like radiometric dating and examining rock layers.
Why is hardness important?
It helps identify and distinguish between different minerals.
How can you classify rocks based on their texture?
By examining grain size, shape, and arrangement.
Name one rock cycle process.
Weathering or melting.
What is cleavage?
The tendency of a mineral to break along flat, even surfaces.
Why is it important to study minerals and rocks?
They provide resources for construction, technology, and help us understand Earth's history.
What is luster?
How shiny a mineral is.
Name one rock cycle process.
Melting, where rocks turn into magma.
How do sedimentary rocks form?
From the compaction and cementation of sediments.
How do you find density?
By dividing an object's mass by its volume.
How do scientists classify rocks?
By examining their mineral content, texture, and formation process.
What tools help find minerals?
Tools like microscopes, hardness kits, and chemical tests.
How do igneous rocks form?
From the cooling and solidification of magma or lava.
Why are rocks important?
They shape Earth's surface and provide materials for human use.
How does luster help?
Luster describes how a mineral reflects light, helping in identification.
What are minerals for rocks?
Minerals are natural compounds that combine to form rocks.
How do minerals form?
Through processes like cooling of magma, evaporation, and high pressure.
How do metamorphic rocks form?
From heat and pressure on other rocks.
How do volcanoes help the rock cycle?
By bringing magma to the surface, which cools to form igneous rocks.
What process forms smaller rocks from larger rocks?
Erosion, which involves the movement and breakdown of rocks.
