Metamorphic rock
Sandstone
Igneous rock
Granite

Answer 1

The type of rock that can be made from the remains of microscopic organisms is **sandstone**. More specifically, if the sandstone contains a significant amount of silica from the remains of microscopic organisms like diatoms, it can be referred to as **diatomaceous earth** or **diatomite**. However, it's important to note that limestone, which is not listed among your options, is also commonly formed from the remains of microscopic organisms such as foraminifera and coccolithophores.
