You would find extrusive igneous rocks. Beyond that it depends on the volcano.
Extrusive, Igneous rocks possibly lavas or ignimbrites.
The student can expect to find volcanic ash, pumice stone, and lava flows in the area around the recently erupted volcano. These samples can provide valuable insights into the composition and nature of the volcanic activity.
They are commonly found under ground or near volcanoes
When lava cools, it forms what is known as an extrusive igneous rock. Volcanoes are also associated with alteration from heat and fluids. Therefore you would expect to find extrusive rocks as well as altered rocks.

Extrusive, Igneous rocks possibly lavas or ignimbrites.
You would expect to find an igneous rock with small crystals near the Earth's surface where the rock cools relatively quickly, such as in volcanic eruptions or magma intrusions that do not have much time to grow large crystals. These rocks are known as volcanic or extrusive igneous rocks.
Yes because there is a volcano there that is still active?

You would expect to find plagioclase feldspar in a greater variety of igneous rocks compared to biotite. Plagioclase feldspar is a more common mineral and is found in both mafic and felsic rocks, while biotite is typically found in intermediate to felsic rocks.
Obsidian is an extrusive rock and is formed from rapidly cooling magma. Obsidian is also known as volcanic glass and one can find only sub-microscopic crystals in it. This is because it was cooled too fastly for large crystals to form. If the material that obsidian consists of were an intrusive rock and had a lot of time to cool down, one would find that it would be composed of easily visible crystals.

You WOULD expect to find metamorphic rocks in the recesses (deep layers) of the Earth's crust. But not in the mantle or core. Metamorphic means changed - and rocks - either sedimentary or igneous - get changed by the heat and pressures found in the deep crust.
Igneous rock is typically found deep in the Earth's crust, formed from the solidification of magma. This process occurs at high temperatures and pressures found deep underground. Examples include granite and basalt.
