  • What is rock salt?
    What is rock salt?
    Rock salt, also known as Halite in the industry, is a mineral formed from Sodium Chloride (NaCl). It is mostly white in color or can be colorless. Rock salt is also found in some other colors like light blue, dark blue, purple, pink, yellow, or gray totally depending upon the amount and type of impurities it contains. The salt lies in the beds of Sedimentary evaporite minerals caused by large lakes and seas drying up. These beds may be thick about hundred meters. Rock salt is basically formed by the evaporation of salty water (like sea water) that contains Na+ and Cl- ions. Rock salt also includes some other salt variations like common salt and table salt. which are required for human life on earth.

  • What is Coquina?
    What is Coquina?
    The answer to this question is C. The sedimentary rock is known as a type of rock that may have been formed because of the accumulation of different particles in one place. For example, there are different organic particles that can be found on the ocean floor. They may all form together in order to form one solid rock that is composed of varying items. The rock found in the ocean floor may be composed of small pebbles, the carcass of dead sea animals, shells, and so much more. Take note that there are also sedimentary rocks that can be found on land. It will be helpful to know the other types of rocks available too.

  • What is a permeable rock?
    What is a permeable rock?
    Permeable objects are those that contain small holes because they allow water or liquid to pass through. Gas can also go through permeable rocks. When these rocks are located in rivers, they will most likely stay fixed in their position because the water can flow through them. Most rocks do not contain pores for water or gas to go through. Sandstones and coal are common examples of permeable rocks. Sometimes rocks that are permeable are weak and can be broken more easily due to the holes in them. The opposite of these rocks are the impermeable rocks which are more common to find. Granite is an example of this. They do not have holes to allow water to go through.

  • What is an igneous or sedimentary rock that has been changed by extreme pressure and heat?

  • What is fossiliferous limestone?
    What is fossiliferous limestone?
    Limestone is any limestone made mostly from calcium carbonate in the form of the minerals calcinate or alginate, that contains an abundance of apparently visible fossils or fossil traces. This rock may take on several different shapes. The fossil fragments are typically corals and foraminifera, which is a type of aquatic amoeba. The fossiliferous limestone is called biosparite limestone under the classification of sedimentary rocks. The limestone can be polished in tiles or slabs; fossil-bearing rocks are used for building pavements. They are also carved as ornamental stones and used in jewelry making.

  • What type of rock is obsidian?
    What type of rock is obsidian?
    Obsidian is igneous rock that forms when specific rock material cools so abruptly that atoms cannot arrange themselves into a crystalline structure. Obsidian is usually an extrusive rock that solidifies above the earth's surface. It can form in a plethora of cooling environments. Obsidian is most often black. It can sometimes be brown, tan or green. It is very rarely blue, red, orange or yellow. Occasionally, two colors of obsidian will be swirled together in a single rock. For example, black, and brown obsidian can be swirled together, which is called mahogany obsidian. Obsidian is found in areas that demonstrate volcanic activity.

  • What is Rhyolite?
    What is Rhyolite?
    Rhyolite is an igneous rock. It can also be considered as the extrusive equivalent to the plutonic granite rock, and consequently, broken rhyolite may bear a same resemblance as granite. Due to the high concentration of silica and low iron and magnesium contents, rhyolite melts are highly polymerized and form highly viscous lavas. They also occur as breccias or in volcanic plugs and dikes. Obsidian is when rhyolites melt and cool too quickly to grow crystals form a natural glass or vitrophyre. Slower cooling of rhyolites forms microscopic crystals in the lava and gives its results in textures such as flow foliations, spherulitic, nodular, and lithophysal structures.

  • What type of rock is Migmatite?
    What type of rock is Migmatite?
    The correct answer to this question is B, metamorphic rock. Migmatites are rocks as well. They are a mixture of metamorphic and igneous rocks. It is created when the rock partially melts. Those melts then recrystallize into volcanic rock. When this occurs, the unmelted metamorphic part and the volcanic part generate a mixture. Migmatites are created during extreme temperatures and are the result of reactions that are solid in the state. In their appearance, they are often tightly folded with light colored veins. Geologists love to observe them, for it is beautiful to look at their black and white layers.

  • What type of rock migmatite is?
    What type of rock migmatite is?
    The correct answer to this question is Metamorphic rock. These types of rocks are changed over time, and the word metamorphic means altered the form, hence the rocks name. The changes occur due to extreme heat and pressure. Temperature and pressure are also how these rocks are formed. The pressure under the Earth's surface forms them, as well as the heat from magma. Tectonic plates collision and frictions are also how the rocks form. Along with metamorphic, there are other prominent rocks, including sedimentary and igneous. There are many favorite metamorphic rocks, including slate, marble, granulite, and quartzite. One famous location made from these rocks is the Taj Mahal, which is made in marble.

  • What is a rock that forms when magma hardens beneath Earths surface called an?
    What is a rock that forms when magma hardens beneath Earths surface called an?
    The answer is D. A rock that forms when magma hardens beneath Earth's surface called an extrusive igneous rock. These types of rocks are formed when magma (which forms lava under the Earth's surface) eventually gets to the surface of the Earth and begins to cool rapidly. Magma usually gets to the Earth's surface through a volcano eruption and can often be found at the base of or nearby a volcano. These extrusive igneous rocks will have small crystals on them made up of different chemicals such as rhyolite, obsidian, andesite, and basalt. If you are ever near a volcano and see anything that resembles magma or extrusive igneous rock, do not get close to it. Often times these will still be hot to the touch and should never be messed with.
