Question
what are three types of rocks and how are the formed
Answers
GPT 3.5
The three types of rocks are igneous rocks, sedimentary rocks, and metamorphic rocks. Here is how they are formed:
1. Igneous rocks: These rocks are formed from the solidification of molten magma or lava. When magma or lava cools and hardens, it forms igneous rocks. Examples of igneous rocks are basalt, granite, and obsidian.
2. Sedimentary rocks: These rocks are formed through the accumulation and compression of sediments, such as sand, mud, or organic materials. Over time, the layers of sediments are compacted and lithified (turned into solid rock) by pressure and minerals. Examples of sedimentary rocks are sandstone, limestone, and shale.
3. Metamorphic rocks: These rocks are formed when existing rocks undergo changes in their structure, mineralogy, or texture due to high temperature, pressure, or chemical reactions. This transformation occurs without the rock melting. Examples of metamorphic rocks are marble, slate, and quartzite.
