meteorite impacts
Cosmic debris bombardment
Meteorite impacts are collisions between space rocks and planetary bodies.
On Earth, these events range from small stones falling harmlessly to catastrophic strikes that reshape landscapes and alter climate.
The Chicxulub impact likely caused the mass extinction that killed the dinosaurs.
Impact craters on the Moon and Mars preserve records of cosmic bombardment over billions of years: Scientists study meteorite impacts to understand planetary evolution.
