NASA satellites continually monitor the Earth, snapping photos and sending information to researchers on the ground.
Most of the time, things seem to be more or less the same as they were the day before, but the Earth is actually constantly changing. Sometimes it changes through discrete events, like landslides and floods. Other times, long-term trends, such as climate change, slowly reshape the land in ways that are difficult to see.
By zooming way out, we can get a new perspective of the events that have changed the Earth. These 10 before-and-after photos show the disasters, trends, and changes that have affected our planet, as seen from space.
