What happens if a planet hits the earth?
1. A few weeks befre the cllisin, mankind fund an unknwn star in the sky, but it will nt d any harm. It will slwly apprach the earth, that is, it will rush t the earth at the speed f 11 kilmeters per secnd, but the speed will gradually increase.
2. After entering the rbit f the mn, disasters ccurred. Due t the gravity f the planet, the earth tide was eight times larger than it is nw. Flds raged n the cast, cuntless casts were destryed, and tsunamis ccurred frequently.
3. 28 hurs befre the cllisin, the planet's gravity increased its speed t 60 kilmeters per secnd. The secnd huge tsunami came, and lightning, hurricanes, trnades and ther disasters that were nt cmmn befre wuld spread all ver the earth.
4. Three minutes befre the cllisin, the planet apprached the earth's atmsphere, which burst ut the light f the mn under cmpressin, and everything n the earth's surface evaprated instantly and was cvered by magma.
5. When the asterid hit the earth, the crust and lithsphere n the sea and land quickly vaprized and disintegrated, and the vaprized material and air were heated t a plasma state f mre than 6000 degrees Celsius, frming a huge verpressure shck wave and spreading arund.
6. After the impact, the larger debris will als hit the earth vilently. The debris f the asterid will break thrugh the vaprized crust, and sme f it will sputter int uter space, with a mass f at least 100 millin tns.
7. The final result is a mass extinctin, but this extinctin is relative. Sme lives disappear, while thers are brn. Just like the end f the age f dinsaurs, human beings gradually evlved t the tp f the fd chain. Withut the extinctin f dinsaurs, maybe human beings wuld nt rule the planet. Therefre, cherish ur beautiful planet. The appearance f life in the universe is a miracle, while extinctin is the nrmal state f the universe.
