porous surface and a deep red or brown color . some of those rosks are transparent and black with a glassy texture. Answer: Granite has a grainy texture composed of visible mineral crystals. Basalt is usually fine grained with a black or black-green color. Pumice can appear full of small bubbles and will float on water. Volcanic cinders are usually dark red to dark black and appear porous. Obsidian will be black to dark brown and opaque to semi-transparent with conchoidal fracturing.

What processes help change metamorphic and igneous rock to sedimentary rocks?
Denudation, Weathering, Erosion, Diagnesis.
What chemical property is most commonly used to classify igneous rock List two physical properties that you could use to identify igneous rocks.?
The most commonly used chemical property to classify igneous rocks is their mineral composition, particularly the relative amounts of silica and other oxides present. Two physical properties that can help identify igneous rocks are texture (such as grain size and arrangement of crystals) and color, which can indicate the mineral content and cooling history of the rock.
What are the characteristics of rock and how do you define them?
Rocks are defined by their mineral composition, texture, and formation processes. They can be classified into three main types: igneous, sedimentary, and metamorphic, each with distinct characteristics. Igneous rocks form from cooled magma or lava, sedimentary rocks consist of accumulated sediments and organic materials, and metamorphic rocks arise from the alteration of existing rocks under heat and pressure. Additional characteristics include color, hardness, and grain size, which help in identifying and classifying rocks.
What processes found at a divergent boundary help form the following rocks?
The process of upwelling magma is found a divergent boundaries. As this magma nears the surface it decompresses, and some of it flows onto the surface of the Earth as lava. Magma that solidifies beneath the surface of the Earth hardens into gabbro while lava on the surface of the Earth hardens into basalt. Both of these are igneous rocks. Metamorphic rocks are formed from the heat flowing from the igneous rocks. Sedimentary rocks are formed from the sediments collecting in the basins created from rifting (that is, the divergent boundaries). Metamorphic and sedimentary rocks are not considered to be formed at divergent boundaries.
What are three types of rock formations explain how each of the three is formed?
the three rocks are igneous ,metamorphic and sedimentary i don't know what it is made up of but that is what i trying to figure out can someone help me please
What is the main type of energy used to help convert metamorphic rocks into igneous rocks?
The main type of energy used to help convert metamorphic rocks into igneous rocks is heat. This heat can come from processes such as magma intrusion, volcanic activity, or tectonic movements, causing the metamorphic rocks to melt and recrystallize into igneous rocks.
What are a basic list of the physical properties of igneous rocks?
Some basic physical properties of igneous rocks include color, texture (such as grain size and shape), density, hardness, and composition (mineral content). Additionally, features like porosity, cleavage, fracture, and luster can help further describe and classify igneous rocks.
What processes help change metamorphic and igneous rocks to sedimentary rocks?
The rock cycle
What are the features that will help you distinguish crystalline metamorphic rock fram a crystalline igneous rock?
Crystalline metamorphic rocks typically exhibit foliation or banding due to the alignment of minerals under pressure, while crystalline igneous rocks lack this feature and have a more uniform texture. Additionally, metamorphic rocks may contain minerals that form under high pressure and temperature, such as garnet or kyanite, which are not typically found in igneous rocks. The presence of parent rock structures, such as sedimentary or igneous rocks, can also indicate metamorphic origins, whereas igneous rocks form directly from the cooling of molten material.
What is the main type of energy used to help convent metamorphic rocks into igneous rocks in the rock cycle?
The main type of energy used to convert metamorphic rocks into igneous rocks in the rock cycle is heat. The increase in temperature causes the metamorphic rocks to melt and then solidify into igneous rocks.
What is the main type of energy used to help convert metamorphic rocks into igneous rocks in the rocks cycle?
Thermal energy -apex (:
What is the main type of enegry used to help convert metamorphic rocks into igneous rocks in the rock cycle?
Heat
What is the main type of energy used to help convert metaphoric rocks into igneous rocks?
lots of heat energy
What is the best clue to tell in extrusive igneous rocks from in instrusive igneous rock?
Extrusive igneous rocks have smaller crystals due to rapid cooling on the Earth's surface, while intrusive igneous rocks have larger crystals due to slower cooling beneath the Earth's surface. This difference in crystal size can help distinguish between the two types of rocks.
What two rock types are formed by transfer of heat?
Igneous an Metamorphic are the two types of rock that are formed with the help of heat .
