Question

Match the geologic settings with the types of rock(s) that can form there. (i = igneous, s = sedimentary, m = metamorphic)

1. Volcanic eruption sites
2. Deep ocean basins
3. Riverbeds and floodplains.
4. High-temperature, high-pressure environments
a) Volcanic eruption sites - _______
b) Deep ocean basins - _______
c) Riverbeds and floodplains - _______
d) High-temperature, high-pressure environments - _______

Answer 1

In volcanic eruption sites, igneous rocks form from cooled magma. Sedimentary rocks form in deep ocean basins and riverbeds/floodplains from sedimentation. High-temperature, high-pressure environments create metamorphic rocks.

Step-by-step explanation:

To match the geologic settings with the types of rocks that can form there:

• a) Volcanic eruption sites - i (Igneous)
• b) Deep ocean basins - s (Sedimentary)
• c) Riverbeds and floodplains - s (Sedimentary)
• d) High-temperature, high-pressure environments - m (Metamorphic)

Volcanic eruption sites are where igneous rocks like basalt and obsidian form as magma cools and solidifies. Deep ocean basins are where sedimentation occurs, leading to the formation of sedimentary rocks such as limestone. Riverbeds and floodplains are also areas where sedimentary rocks like sandstone and shale can form from weathered rock fragments. Lastly, high-temperature, high-pressure environments found deep within the Earth lead to the formation of metamorphic rocks like slate and schist.
