How are rocks classified into one of these three groups?
Rocks are classified into three groups based on how they are formed. Igneous rock is formed when magma cools and crystallizes. Sedimentary rock is formed when the products of weathering and erosion are compacted and cemented to form new rock. Metamorphic rock is formed when existing rock is changed by heat, pressure or chemical change into a new kind of rock.
Write a summary of the the three types of rocks and how they are formed?
igneous rocks are formed by cooling lava from volcanos. Obsidian is an igneous rock. Sedimentary rocks are formed by particles being deposited by water. Sandstone is a sedimentary rock. Metamorphic rocks are formed when heat, pressure, and chemical reactions change existing rocks. Granite is a metamorphic rock.
How in metamorphic rock formed?
Metamorphic rocks are rocks formed from igneous, sedimentary and even other metamorphic rocks. Heat, pressure and chemical action can cause a rock to change into another rock. Pressure from the rocks on top of them squeezes and folds the rock. Their grains come close together and they become less porous. Heat and chemicals may cause changes in the arrangement of mineral particles or new minerals may be formed.
Metamorphic rock formed from sandstone?
Quartzite is a metamorphic rock formed from sandstone.
What are some properties of metamorphic rocks?
made with heat and pressureis formed undergroundigneous and sedimentary rocks can change into metamorphic rockoften chips into slates, sheets, and slabsgneiss is a type of metamorphic rock
Which of the types of rocks can only be formed by the chemical change of another rock?
metamorphic
What types of rocks can only be formed by the chemical change of another rock?
metamorphic
What is rock that is changed by heat pressure or chemical change?
Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.

What type is rock is formed if rock undergoing a metamorphic change melts?
igneous
Where and under what conditions are metamorphic rock formed?
Heat and pressure deep beneath Earth's surface can change any rock into metamorphic rock

When heat and pressure cause a rock to change what type of rock is formed?
Metamorphic Rocks.

How do heat and pressure change sedimentary rock?
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
Metamorphic rock formed from sandstone?
Quartzite is a metamorphic rock formed from sandstone.
Is a geode a metamorphic rock?
A geode is a chemical sedimentary structure formed by mineral precipitation, similar to the way sedimentary cave structures are formed.
