Debris from the explosion was thrown into the atmosphere, severely altering the climate, and leading to the extinction of roughly 3/4 of species that existed at that time, including the dinosaurs.
Many asteroids of this type are now known; their orbits pass through the inner solar system and cross Earth's orbit.
Some of these could potentially hit Earth in the future.
Most, but not all are smaller than the one that hit us 65 million years ago.
According to abundant geological evidence, an asteroid roughly 10 km (6 miles) across hit Earth about 65 million years ago.
This impact made a huge explosion and a crater about 180 km (roughly 110 miles) across.

) Non sono antipasti veri e propri, ma danno un'idea molto precisa del mondo di mangiare garganico, le bruschette o l'acqua sale: pane raffermo abbrustolito o ammorbidito nell'acqua, condito con pomodori, cipolla cruda tagliata, origano ed olio di oliva, o, nel caso della bruschetta tradizionale, soltanto con olio di oliva, dopo aver strofinato sul pane uno spicchio di aglio crudo.
I wish the talk show hosts would shut the eff up about it already! Clockwise from top left: Microraptor gui (a winged theropod), Apatosaurus louisae (a giant sauropod), Edmontosaurus regalis (a duck-billed ornithopod), Triceratops horridus (a horned ceratopsian), Stegosaurus stenops (a plated stegosaur), Pinacosaurus grangeri (an armored ankylosaur) Dinosaurs are a diverse group of reptiles of the clade Dinosauria that first appeared during the Triassic period.Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201 million years ago.While dinosaurs were ancestrally bipedal, many extinct groups included quadrupedal species, and some were able to shift between these stances.Elaborate display structures such as horns or crests are common to all dinosaur groups, and some extinct groups developed skeletal modifications such as bony armor and spines.
