Metamorphic Rock

Some rocks are old.These sometimes have fossils.This is because the rocks used to be mud.When a inprint is made on the mud and does not get washed away the mud hardends the inprint stays.Years later the inprinted mud turns into a rock.If you get lucky and crack that rock open, the inprint is there.

Jamaica and other islands of the Antilles evolved from an arc of ancient volcanoes that rose from the sea millions of years ago. During periods of submersion, thick layers of limestone were laid down over the old igneous and metamorphic rock.

Foliated means the crystals are formed in parallel bands. This is formed when pressure crushes the rock so that it becomes denser. This causes the crystals to produce band as space runs out at 900 to the pressure. E.g. Weight of rocks above produce bands horizontally.

When sand is subjected to high pressure and high temperature, it can transform into a type of metamorphic rock called quartzite. Quartz grains in the sand recrystallize and fuse together under these conditions, resulting in the formation of a hard, compact rock with a granular texture.

No, the Three Sisters in Oregon are not made of metamorphic rock. They are volcanic peaks formed from volcanic activity in the area. Metamorphic rocks are rocks that have undergone changes due to heat and pressure over time.

Gravel is typically made up of a mix of different rock types, including igneous, sedimentary, and metamorphic rocks. The specific composition of gravel can vary depending on the location where it is found.

You will get marble, a metamorphic rock, from limestone. Marble forms when limestone is subjected to heat and pressure, causing it to recrystallize and change in mineral composition.

The weight of metamorphic rocks varies depending on the size and composition of the rock. A small sample of metamorphic rock may weigh a few grams, while a larger boulder could weigh several tons. It is important to note that the weight of a rock is typically measured in kilograms or metric tons rather than grams.

the marble arch was made in 1867

slate which only contains the composition mica

quartzite and marble as well

Metamorphic rocks can be pushed to the surface through tectonic processes such as mountain-building events, where intense pressure and heat from deep within the Earth cause rocks to be uplifted and exposed at the surface. Erosion can also play a role in uncovering metamorphic rocks that were once buried deep beneath the Earth's surface.

yes it it.....i have proof from my science book from my school. also this rock is formed from existing rocks that is changed by heat, preasure or chemical reactions. also another example of an metamorphic rock is a soap stone which have mostly a gray or black or both color to it.

Schist is a typical foliated metamorphic rock.

Initially, one merely has a laminated sedimentary rock.

When this is subjected to heat and pressure, then some of the old minerals are destroyed and new ones formed from the available assemblage.

From the types of new minerals formed, one may deduce the heat and pressure of the metamorphism.

The date of the metamorphism is estimated by dating the mineral last formed - the one with the lowest freezing point. [Commonly mica].

The rock may then be subjected to further stresses which will produce folds of some complexity. This may be followed by intrusions of granites or volcanics.

When basalt undergoes metamorphism, it can change into a metamorphic rock called greenstone. Greenstone is a fine-grained metamorphic rock that forms from the alteration of basalt through metamorphic processes like recrystallization and the growth of new minerals.

Metamorphic rocks can have a range of textures, from smooth to rough, depending on the minerals present and the intensity of the metamorphic processes they underwent. Some metamorphic rocks, like gneiss, can have a rough texture due to the presence of minerals like quartz and feldspar.

Scientists believe that when Earth was first formed, its crust was made of molten rock that eventually cooled and solidified into igneous rock. Over time, these rocks were subjected to heat and pressure, leading to the formation of metamorphic rocks, which make up a significant portion of Earth's crust today.

Greenstone rock can have a smooth texture, with a glossy or waxy appearance. It may also have a fine-grained or compact texture, depending on the specific mineral composition and how it has been weathered or altered over time.

In Pokemon Emerald, Slateport City's harbor is located in the southeastern part of the city. It is where the player can take the S.S. Tidal ferry to other locations, such as Lilycove City and Battle Frontier.

Metamophic rock came from the volcano and it's part of rocks and minerals.

Weathering and erosion can break down igneous and metamorphic rocks into smaller pieces, which are then transported and deposited as sediments. This process involves physical and chemical breakdown of the rocks due to exposure to the elements and natural forces like wind, water, and ice.

Deposits of anthracite can be found in various countries around the world, including the United States, Russia, China, and South Africa. Additionally, smaller deposits can be found in countries such as Ukraine, Vietnam, and Australia.

Mudstone can be changed into a metamorphic rock through the process of metamorphism, where it is subjected to high temperature and pressure. This causes recrystallization of minerals, reorganization of grains, and the development of new mineral assemblages, transforming the mudstone into a new metamorphic rock such as slate, schist, or gneiss.

It forms deep inside the Earth's surface
