Answer:
thin and solid
Explanation:
The "crust" is the outermost part of the Earth. It only accounts for a very small portion of the Earth's mass and that makes it thin. It is made up of different sands, rocks and minerals. This is the reason why it is solid and not liquid (nor is it soft and flexible). It's temperature is not that hot when compared to the inner core. It has the same temperature with the Earth's atmosphere. This allows humans to continue thriving on Earth.
