What are the 4 attributes of rocks?

What are the 4 attributes of rocks?

Rocks are made out of minerals and have many different properties, or characteristics. Streak is the color of a rock after it is ground into a powder, and luster tells how shiny a rock is. Other properties include hardness, texture, shape, and size.

What are the 5 characteristics of rocks?

Characteristics of Rocks

  • Colour.
  • Streak.
  • Hardness: Moh’s scale of hardness.
  • Cleavage.
  • Fracture.
  • Luster.

What other attributes would you use to sort the rocks?

Rocks can be classified into types by testing for certain characteristics. These tests include hardness, streak or color, acid, and magnetism. 1. igneous – hard rocks formed from cooled molten material.

What are the 7 properties of rocks?

Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

What are the 6 characteristics of rocks?

The following properties are very useful for identification purposes:

  • Hardness.
  • Cleavage.
  • Luster.
  • Color.
  • Streak rock powder.
  • Texture.
  • Structure.

How do you describe rocks for kids?

A rock is a solid made up of a bunch of different minerals. Rocks are generally not uniform or made up of exact structures that can be described by scientific formulas. Scientists generally classify rocks by how they were made or formed. There are three major types of rocks: Metamorphic, Igneous, and Sedimentary.

What are the 3 classifications of rocks?

There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.

What are the 3 characteristics of rocks?

The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment.

What is a rock easy definition?

A rock is a naturally occurring solid. It is made of minerals (which are crystalline), or other mineral-like substances. That means the Earth’s crust is made of rock. The different minerals in the rocks make different kinds of rock. Rock is often covered by soil or water.

What are the three types of rocks describe each?

Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.

What are the characteristics of rock?

Rocks are characterized by mineral and chemical composition, texture and permeability. Structure and habit, hardness, luster, diaphaneity, color, streak, tenacity, cleavage, fracture, parting, and specific gravity. Classification. Ingenious, sedimentary and metamorphic.

What are the properties of a rock?

Rock properties are the measurable properties of rocks that are a measure of its ability to store and transport fluids, ionic species, and heat. Rock properties also include other measurable properties that aid in exploration or development of a reservoir.

What are five properties of rocks?


  • Streak
  • Hardness: Moh’s scale of hardness
  • Cleavage
  • Fracture
  • Luster
  • What are the features of rock?


  • Streak: Powder is obtained by crushing the mineral.
  • Cleavage: The cleavage of the minerals is its capacity to split more readily in certain directions than in others,due to the arrangement of the atoms.
  • Luster: Appearance of mineral in ordinary light (that is the appearance due to reflected light).
