Which statement is true of rocks?
What are the properties of a mineral? What type of rock is formed when a volcano explodes? Which statement is true of all rocks? They all are made of minerals.
What are the rocks answer?
A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth’s crust, or lava cools on the ground surface or the seabed.
Which is true about rocks and minerals?
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
Which is true about all minerals?
To be classified as a “true” mineral, a substance must be a solid and have a crystal structure. It must also be an inorganic, naturally-occurring, homogeneous substance with a defined chemical composition. A crystal structure is the orderly geometric spatial arrangement of atoms in the internal structure of a mineral.
Which statement best describes how minerals are different from rocks?
Answer: A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids.
Do you know about rocks?
There are three basic types of rock: igneous, sedimentary, and metamorphic. Extremely common in the Earth’s crust, igneous rocks are volcanic and form from molten material. They include not only lava spewed from volcanoes, but also rocks like granite, which are formed by magma that solidifies far underground.
What is true about the elements that make up a mineral?
All minerals have a definite chemical makeup. A few minerals are made of only one kind of element. For example, the mineral hematite has two iron atoms for every three oxygen atoms. The mineral magnetite has three iron atoms for every four oxygen atoms.
Which is true?rocks do not contain any mineral?
Most rocks are composed of a – Brainly.com Which statement is true? Rocks do not contain any mineral matter. Most rocks are composed of a single mineral. Most rocks are made up of a mixture of minerals. The last Most rocks are made up of a mixture of minerals.
What kind of rock is a hand specimen?
A hand specimen is a small piece of the outcrop that can be examined closely After an explosive volcanic eruption on an island, the surrounding sea is full of light-gray, floating rock. What must it be?
Why is magma less dense than the surrounding rock?
Correctd. all of the possible answers are correct. because it is less dense than the surrounding rock. are fed magma from flux melting. may melt if heat is transferred to it from hot mantle rock rising up into the crust. As a sample moves from Point A to Point B in this diagram, what happens? It begins to melt as a result of decompression.
What is the origin of foliation in metamorphic rock?
. the origin of formation. by grains being cemented together. The texture produced when minerals within a metamorphic rock are layered parallel to each other, as shown by the red line, is called foliation. c. is composed of interlocking minerals that grew together.
