Interesting Facts about Rocks. The word "igneous" comes from the Latin word "ignis" which means "of fire." Ores are rocks that include minerals that have important elements such as metals like gold and silver. Sedimentary rocks form layers at the bottoms of oceans and lakes.
Basalt is a hard, black-colored extrusive igneous rock composed mainly of plagioclase and pyroxene minerals.. Pumice is a light-colored vesicular extrusive igneous rock. It is composed primarily of silica and A1-oxide but may contain metal oxides, calcite, or salts. Obsidian is a dark-colored, extrusive igneous rock that forms due to the rapid …
Chemical sedimentary rocks form when mineral constituents in solution become supersaturated and inorganic precipitation occurs. Examples include rock salt, gypsum, and some limestones. Rock salt or halite is an example of a single mineral forming a rock. Most chemical sedimentary rocks contain multiple minerals.
Basically, geodes are sedimentary rocks, the crystals within the bubbles forming as a result of a chemical reaction that leads to precipitation of minerals that become those crystals. The outer shell of a geode is made of a very hard rock, and crystals form inside geodes only when the perfect combination of temperature, pressure changes and ...

Sandstone is a sedimentary rock that forms in this way. Sedimentary rock also may form from the remains of dead animals or plants. Limestone is a sedimentary rock that is made up of the shells and stony skeletons of certain kinds of living things. Metamorphic rock forms from old igneous or sedimentary rock. Several forces can change old rock ...
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic …
Those that form from organic remains are called bioclastic rocks, and sedimentary rocks formed by the hardening of chemical precipitates are called chemical sedimentary rocks. Table 4.2 shows some common types of sedimentary rocks and the types of sediments that make them up. Figure 4.12: This cliff is made of a sedimentary rock called ...
Fact 3: Sedimentary rocks are classified into four groups. Based on how they were formed, sedimentary rocks are typically divided into four groups. Clastic sedimentary rocks are made up of fragments that have been consolidated by silicate minerals during geologic time. They can be any type of mineral, but the majority of them are made up of ...
