A queen size mattress is 60 inches wide and 80 inches long, which leaves enough space for people to roll over without bothering their sleeping partner. It also gives solo sleepers plenty of room to stretch out. At 6.5 feet long, queen mattresses are perfect for tall sleepers who need extra legroom.

Most of the volcanoes probably stopped erupting about a billion years ago, but NASA findings have suggested there might still have been active lava flow 100 million years ago, when dinosaurs were still roaming.
