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.
What main group of rock can be formed from rock which undergone a change?
Metamorphic rock is formed from rock that has undergone a change due to heat and pressure. This process causes the original rock to recrystallize into a new form with different physical and chemical properties. Examples include marble and slate.
Metamorphic rocks can only be formed from?
Metamorphic rocks can be formed from any pre-existing rock type (igneous, sedimentary, or other metamorphic rocks) that undergoes intense heat, pressure, or chemical changes without melting. This process causes the minerals in the rock to recrystallize and reorganize, resulting in a new metamorphic rock with different properties.
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.
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.
What types of rocks can only be formed by the chemical change of another rock?
metamorphic
Which of the 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.
What main group of rock can be formed from rock which undergone a change?
Metamorphic rock is formed from rock that has undergone a change due to heat and pressure. This process causes the original rock to recrystallize into a new form with different physical and chemical properties. Examples include marble and slate.
How do heat and pressure change sedimentary rock?
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
What kind of rock is formed with heat and pressure?
Metamorphic rock is formed through heat and pressure acting on existing rocks, causing them to recrystallize and change their mineral composition without melting. Examples include marble, slate, and schist.
What rock is formed from high heat and pressure?
Metamorphic rock is formed from high heat and pressure acting on existing rocks, causing them to recrystallize and change in composition and texture. Examples of metamorphic rocks include marble, slate, and schist.
Is a geode a metamorphic rock?
No, a geode is not a metamorphic rock. Geodes are formed in sedimentary or igneous rocks and are cavities lined with mineral crystals. Metamorphic rocks are formed from existing rocks that undergo a transformation due to heat and pressure.
