Here's a breakdown:

* Quarry: A quarry is an open-pit mine where stone is extracted. They are usually located in areas where the rock is exposed at the surface or near the surface.

* Stone: This is a broad term referring to various types of rock, such as granite, marble, limestone, sandstone, etc., each with different properties and uses.

* Slate: A specific type of metamorphic rock that splits easily into thin sheets.

Therefore, both stone and slate are obtained from quarries.
