answer:true
These minerals are called evaporites.
Obsidian is an extrusive igneous rock, formed from rapidly cooling lava.
A volcano is made of extrusive igneous rock. The specific type of igneous rock will vary from one volcano to another.
An extrusive igneous rock.
Rock salt, rock gypsum, and some forms of limestone.
Flint is a chemical sedimentary rock formed from the precipitation of silica rich solutions in layers of marine sediments.
These minerals are called evaporites.
Coal is neither extrusive nor intrusive. Coal is a sedimentary rock that forms from the accumulation and compaction of plant material over millions of years. It is typically found near the Earth's surface in sedimentary basins and is not formed through volcanic or igneous processes like extrusive or intrusive rocks.
Chemical
False. Intrusive igneous rock forms underground when magma cools and solidifies slowly. Extrusive igneous rock forms when magma erupts onto the Earth's surface and cools quickly.
False
Obsidian is an extrusive igneous rock, formed from rapidly cooling lava.
false
Halite and Gypsum, they are called Evaporites and are both rocks and minerals
No, calcite is not considered extrusive; it is a mineral that typically forms through sedimentary processes or as a result of biological activity, such as the accumulation of calcium carbonate from marine organisms. Extrusive rocks, on the other hand, are formed from the rapid cooling of lava at the Earth's surface, leading to volcanic rocks like basalt or pumice. Calcite is commonly found in limestone and marble, which are sedimentary and metamorphic rocks, respectively.
Clastic sedimentary rock forms when fragments of preexisting rocks are compacted or cemented together. Organic sedimentary rock forms from the remains of plants or animals. Chemical sedimentary rock forms when minerals precipitate from a solution or settle from a suspension.
The sedimentary rock formed from minerals precipitating from a solution is called chemical sedimentary rock. It is formed through processes such as evaporation or chemical reactions, without the involvement of organic material or clastic particles.
