Rocks are typically composed of minerals, which are naturally occurring solid substances with a defined chemical structure. The most common minerals in rocks include quartz, feldspar, and mica, among others. Additionally, rocks can also contain organic materials or fragments of other rocks. Their composition can vary widely, leading to the classification of rocks into three main types: igneous, sedimentary, and metamorphic.

ferro magnesium silicate rocks
What are rock composed of weathered rocks called?
Weathered rocks that are composed of smaller fragments and grains are referred to as sedimentary rocks. These rocks are formed through the process of erosion, transportation, deposition, and lithification of the weathered materials.
What best describes bedded gypsum and halite?
Bedded gypsum and halite are sedimentary rocks that form in evaporite environments. Gypsum is a soft mineral composed of calcium sulfate, while halite is composed of sodium chloride. These rocks typically form in arid climates where evaporation rates exceed precipitation, leading to the deposition of salts and minerals.
How are sills and dikes arranged in relation to the surrounding rocks?
Igneous rock makes dikes and sills. Basalt or Diabese Dikes are actually usually composed of dolerite.
What is the name of a sedimentary rock usually based on?
Sedimentary rocks are typically classified based on their composition and grain size. Common names include sandstone (composed of sand-sized grains), limestone (composed of calcite or aragonite minerals), and shale (composed of clay-sized particles).
Rocks are usually composed of to or more what?
minerals
Which rock is usually composed of several different minerals.?
The majority of rocks are composed of a variety of minerals. Monomineralic rocks are rare.
Which of the following describes what rocks usually are composed of?
Rocks are usually composed of minerals, which are naturally occurring inorganic solids with a specific chemical composition and crystal structure. These minerals are formed through various geological processes such as cooling and solidification of molten rock or precipitation from mineral-rich solutions. Additionally, rocks may also contain organic materials, such as fossils or plant remains.

Volcanoes are composed of what rocks?
http://en.wikipedia.org/wiki/Volcano volcanoes can be composed of a variety of igneous rocks.
Which two rocks are made from rounded grains?
Conglomerate and sandstone are rocks made from rounded grains. Conglomerate consists of larger, rounded gravel-sized particles cemented together, while sandstone is composed of smaller, rounded sand-sized grains cemented together.
mantle is composed of these rocks?
ferro magnesium silicate rocks
Rocks are made of one or more of these?
Rocks are composed of differing combinations of thousands of naturally occurring minerals--or pieces of other rock particles cemented together--or in some cases, lithified organic matter.All rocks are composed of some form of minerals. The exact type of rock and their specific appearance is determined by the elements that are combined with these minerals.
