Is sedimentary rock formed from cooling magma?
No, sedimentary rock is formed from the deposition and compression of sediment such as sand, silt, and clay. Cooling magma forms igneous rock when it solidifies.
What does each indicate to a geologist?
Igneous rock: Formed from the cooling and solidification of magma or lava. Sedimentary rock: Formed from the accumulation and compression of sediment. Metamorphic rock: Formed from the alteration of existing rock due to high heat, pressure, or chemical processes.
Are sedementary rocks formed below Earth's surface as magma?
No, sedimentary rocks are formed on the Earth's surface by the accumulation and compaction of sediment materials like sand, silt, and clay. Magma, on the other hand, solidifies below the Earth's surface to form igneous rocks.
What different types of rock are there?
The three main types of rock are igneous (formed from cooled magma or lava), sedimentary (formed from compressed sediment), and metamorphic (formed from existing rock that has been subjected to heat and pressure). Each type has unique characteristics and formation processes.
What boundary is formed when magma rises to the surface and new crust is formed?
A divergent boundary is formed when magma rises to the surface and new crust is formed. This process occurs at mid-ocean ridges where tectonic plates move away from each other, allowing magma to fill the gap and solidify into new oceanic crust.
