Lava slowly flowing out of a fracture in the Earth's surface :)
Slow cooling in the upper mantle
Diorite typically forms under conditions of slow cooling and crystallization deep within the Earth's crust. This rock type is commonly found in the roots of mountain chains or in the cores of large igneous intrusions.

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.
Obsidian is formed as extruded lava with a high silicon content that cools quickly. So the environment would be a volcano.
Slow cooling in the upper mantle
Coarse-grained extrusive rocks like dacite typically form under conditions of relatively slow cooling, which allows larger crystals to develop. This often occurs in volcanic environments where magma is expelled from a volcano and cools quickly upon reaching the surface, yet retains some degree of insulation, such as being trapped in a thick lava flow. The presence of gas bubbles and the viscosity of the lava can also influence crystal growth, leading to a textured appearance. However, true coarse-grained textures are more characteristic of intrusive rocks; dacite is generally fine-grained due to rapid cooling, suggesting a need for reconsideration of the classification.
Slow cooling in the upper mantle
A coarse-grained intrusive rock like diorite typically forms under conditions of slow cooling and solidification of magma beneath the Earth's surface. This process occurs in a plutonic environment, where the heat from the magma allows for the growth of large mineral crystals. The resulting texture is characterized by visible grains of minerals such as plagioclase feldspar, biotite, and hornblende. Diorite often forms in subduction zone settings, where oceanic crust is forced beneath continental crust, leading to the generation of magma.
Diorite typically forms under conditions of slow cooling of magma deep within the Earth's crust, allowing larger crystals to develop. This slow cooling occurs in a plutonic environment, where the magma is insulated from rapid temperature changes. The presence of a mix of minerals, including feldspar, quartz, and biotite, contributes to its coarse-grained texture. Thus, diorite is expected to form in tectonic settings where magma intrudes into cooler rock formations, such as continental crust.

it depends on what year level you are in and of coarse what school and country.
Extrusive rocks produced by an explosive volcano are likely to be dark in color because they cool quickly on the Earth's surface, preventing mineral crystals from forming. This rapid cooling results in a fine-grained texture that appears dark in color due to the presence of minerals like olivine or pyroxene.
Extrusive, Igneous rocks possibly lavas or ignimbrites.
You would find extrusive igneous rocks. Beyond that it depends on the volcano.

Diorite typically forms in the Earth's crust during the cooling and solidification of magma deep underground. It is commonly found in association with mountain-building processes, such as subduction zones and continental collisions. Diorite can also form through the crystallization of magma chambers within the crust.
