intusive igneous
The type of volcanic rock closest to the crater is typically the youngest and freshest in composition. This rock is referred to as volcanic glass or obsidian, which forms when lava cools rapidly with minimal crystal growth. It is commonly found near the crater due to its recent eruption and proximity to the volcanic activity.
Igneous rock eroded in a river will eventually form sediment, which can be compacted and cemented to become sedimentary rock. Examples of sedimentary rocks include sandstone, shale, and limestone.
Lava is molten rock that flows on the Earth's surface during a volcanic eruption. Magma is molten rock beneath the Earth's surface. A crater is a bowl-shaped depression near the summit of a volcano that forms after an eruption.
The opening of the volcano is called crater. A crater may be large in dimension or deep. This is where the magma erupts.
Igneous rock is produced by the cooling and solidification of molten rock. This process can occur both beneath the Earth's surface, forming intrusive igneous rocks, and at the surface, forming extrusive igneous rocks.
The kind of rock you see forming in Puu Oo crater is extrusive igneous. This type of rock is formed by lava.
This latest phase of eruptive activity at Kilauea volcano started unceremoniously on 24 Feb with the appearance of a small amount of molten lava deep within the Pu'u 'O'o crater, visible only from above. - See more at www.Cha Cha.com
Cinder Cones are composed of rock fragments and the eruption of cinders. The rock fragments pile up around a single crater forming a Cinder Cone.
The formation you are referring to is likely an impact crater. When an asteroid hits the Earth, it can create a large crater by displacing the ground and forming a bowl-shaped depression. The impact can also cause debris to be ejected in all directions around the crater.
Rock layers that are forming are stratifying.
The planet Mercury is composed of rock. Its close proximity to the sun prevents any kind of gaseous atmosphere from forming.
An Introduction to the Rock-Forming Minerals was created in 1966.

No. Silicates are the largest group of rock forming minerals.

Sedimentary rock. Because when weathering and erosion occurs to igneous rock, the igneous become sediments and the sediments condense and cool, forming sedimentary rock. Therefore, sedimentary rock doesn't need heat to form.
