How big are the particles in metamorphic rock compared to those in sedimentary rock?
If by particles you mean the size of the crystals, then the crystals in metamorphic rock are often larger than in the sedimentary rock. High heat and pressure can cause the minerals to recrystallize. This would be the case in the metamorphosis of limestone (sedimentary) to marble (metamorphic).
What else can I help you with?
3 main categories of rocks?
Igneous--those that form directly from a molten state. Sedimentary--those that form from eroded particles of various sizes from other rocks. Metamorphic--igneous and sedimentary rocks, and sometimes metamorphic rocks, that undergo a transformation from heat and/or pressure.
Which is the oldest rock sandstone or shale?
Sandstone is typically older than shale, as sandstone forms from the consolidation of sand particles through compaction and cementation, while shale forms from the compaction of clay and silt particles. Sandstone is generally associated with sedimentary environments that occurred earlier in geological history compared to those where shale forms.
Which of the following is NOT one of the three types of rock igneous sedimentary metamorphic magma?
When magma is cooled and hardened, it is an igneous rock. That being said, there's only three left and those three are the three types of rocks. Igneous, metamorphic, and sedimentary.
What are the processes that can cause igneous or metamorphic rock to turn into sedimentary rock?
The metamorphic or igneous rock would have to be weathered and eroded until it is only particulates. Those particulates must then be forced together as a layer under gravitational pressure. These particulates will then become sedimentary rocks.
How can an igneous or metamorphic rock change into a sedimentary rock?
A sedimentary rock can change from that to a metamorphic rock then into an Igneous rock. e.g. Mudstone (sedimentary) is in the Zone of Diagenesis, when it is subjected to regional metamorphism (in mountain belts) it changes from a mudstone to a slate (low grade) then to a Phillite (medium grade) then a Schist (medium) then a gneiss (high grade) then into a Milonite (high grade) then once past the line of partial melting it has so much pressure and so much temperature that it turns into an Igneos rock. This is the basic explanation of this. If you want to know more, just ask me.Sedimentary rocks are changed into metamorphic by being buried deep enough that the heat and pressure alter their text, mineralogy, or other characteristics.
Is metamorphic rock sedimentary?
No, metamorphic rock is not sedimentary; those are two different types.

What rocks can be changed to metamorphic rocks?
Sedimentary,and Igneous.Metamorphic can change to either one of those.
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.

Sandstone is typically older than shale, as sandstone forms from the consolidation of sand particles through compaction and cementation, while shale forms from the compaction of clay and silt particles. Sandstone is generally associated with sedimentary environments that occurred earlier in geological history compared to those where shale forms.
What is sedimentary metamorphic and igneous?
Sedimentary rocks are made from particles of sand or other material laid own in layers by water action and compressed to form stone (Sandstone, Limestone). Igneous rocks are those which froze or crystallized from a molten state (Volcanic lava, Granite). Metamorphic means altered from it's original state by heat, pressure or a combination of the two (Marble is metamorphosed Limestone).
What is an objects that can represent igneous sedimentary and metamorphic?
Those are the three different types of rocks. Igneous means having formed from lava, sedimentary is dust, dead animals, leaves, sediments (funnily enough), and metamorphic is when one rock has changed into another. :)
Is iron ore igneous metamorphic or sedimentary?
Iron ore is primarily classified as a sedimentary rock. It forms through the accumulation of iron-rich minerals, often in sedimentary environments like lakes and oceans. Some iron ore deposits can also result from metamorphic processes, but the majority are sedimentary in origin, particularly those found in banded iron formations.
What rocks are igneous sedimentary and metamorphic?
Igneous rocks are those formed by the solidification of magma. Sedimentary rocks are formed by the lithification of the sediments which accumulate from the erosion of preexisting rocks of all types. They also included rocks form from animal and plant remains. Metamorphic rocks are formed when sedimentary or igneous rocks are heated and or squashed.
Which metamorphic rock would contain more different minerals?
Metamorphic rocks that form from the alteration of sedimentary rocks, such as schist or gneiss, typically contain a greater variety of minerals. This is because they can incorporate and transform the minerals present in the original sedimentary rock, along with those introduced during the metamorphic process. Additionally, the presence of varying pressure and temperature conditions can lead to the formation of different mineral assemblages. Therefore, rocks like schist or gneiss are likely to contain more diverse minerals compared to those formed from igneous parent rocks.
Are igneous sedimentary and metamorphic rocks found in Sacramento?
Yes, Sacramento is primarily underlain by sedimentary rock formations, particularly those from the Sacramento Valley. While igneous and metamorphic rocks are not as common in the immediate area, they can be found in the surrounding Sierra Nevada region. Overall, sedimentary rocks are the most prevalent in Sacramento itself.
What are three groups of rock called?
Igneous, Sedimentary, Metamorphic. Igneous rocks are made of solidified magma. Sedimentary rocks are those that are made by the weathering or erosion of soil of Earth. Metamorphic rocks are when rocks are changed from one material to another; new minerals are created.
