What distinguishes the three classes of rocks from one another?
There are three main types, or classes, of rock which are:***the differences among these rocks have to do with how they are formed as shown below****.sedimentary, these rocks are joining of pre existing rocks. is kind of like lumps of many small rocks.metamorphic: rocks that have changed due to then being moved or changed in any kind of way. these are the typeshe most rocks areigneous: these are formed by material that comes from the cooling and remains of magma. this is the least common form of rock.
Sedimentary rocks that formed organically typically contain what?
Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.
Changed rocks are called?
Changed rocks are called metamorphic. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, through the use of heat and pressure.Metamorphic rocks
What are rocks changed by intense pressure and heat become new rocks called?
Rocks changed by intense pressure and heat become new rocks called metamorphic rocks. These rocks form when existing rocks undergo changes in texture and mineral composition due to high temperatures and pressures. Examples of metamorphic rocks include marble, slate, and gneiss.
What rock is formed from pieces of other rocks?
Sedimentary rock is formed from pieces of other rocks, minerals, and organic materials that have been compacted and cemented together over time. Examples of sedimentary rocks include sandstone, shale, and limestone.
How are each of the major types of rocks formed?
Igneous rocks are formed from magma or lava cooling and hardening. Sedimentary rocks are formed from sediments being compressed and cemented together. Metamorphic rocks are rocks that are changed by extreme heat and pressure.
What rocks are formed when existing rocks are changed into new rocks?
metamorphic rocks.
What is formed when igneous rocks and sedimentary rocks are changed due to heat and pressure?
When igneous rocks and sedimentary rocks are changed due to heat and pressure, they can form metamorphic rocks. This process is known as metamorphism, and it often results in the rocks being altered in texture and mineral composition. Metamorphic rocks can include marble, schist, and gneiss.
How did rocks get formed?
There are 3 main ways for them to be formed. Sedimentary rocks are formed from dirt and sand, and can be found in rivers. Igneous rocks are made from molten magma or lava. Metamorphic rocks are made from already existing rocks, and are changed by pressure or temperature.
How are metmorphic rocks formed?
Metamorphic rocks are rocks which have changed from one form to another due to intense heat or pressure. Any rock (sedimentary, metamorphic, and igneous) can be changed into a metamorphic rock.

What are some examples of rock types?
Igneous rocks - rocks formed from molten rock of the mantle Sedimentary rocks - rocks found in streams Metamorphic rocks - rocks changed by the effects of heat and pressure
Where are you most likely to find all three types of rock being formed?
You are most likely to find all three types of rock being formed at convergent plate boundaries, particularly subduction zones. Here, sedimentary rocks are subjected to heat and pressure, forming metamorphic rocks. As tectonic plates collide and melt, igneous rocks are also formed.
How can metamorphic rocks be changed into sedimentary rocks?
It can be changed by being broken down in the weathering process just like all rocks. The resulting sediment can then be lithified to for a sedimentary rock.
What are sedimentary rocks ad how are they formed?
Rocks made from sediments being compacted & cemented together.
Which rock is most likely to contain minerals that have not been changed?
Sedimentary rocks are most likely to contain minerals that have not been changed, as they are formed from the accumulation and cementation of materials without undergoing high temperatures or pressures that could alter their mineral composition. Examples include sandstone and limestone.
Why is clay sedimentary?
Clay is formed from rocks by those rocks being weathered to minute particles, those particles being washed in a river and then deposited. As clay is formed of these "sediments" it is sedimentary.
