Question

has a glassy texture
cooled very quickly from lava
was formed on Earth's surface
has a coarse texture

Answer 1

Emily finds a rock with crystals 2 cm large. Her rock has a coarse texture.

This is because larger crystals typically indicate a slower cooling process, which allows for the growth of larger crystalline structures. Rocks with a coarse texture are generally formed from magma that cools slowly beneath the Earth's surface, rather than being formed from lava that cools quickly on the surface.
