Why was an asteroid with only a 10-15 km (7-8 mile) width able to wipe out the dinosaurs and cause the extinction of 75% of all species on Earth?

That width is less than the distance I drive from my house to the grocery store. Why was that size of an asteroid able to cause such catastrophic damage?

the asteroid hit really really hard. 1 billion nuclear bombs going off at the same time. The heat from the explosion cooked everything around it. Then extremely hot rocks and boulders that bounced into the sky from the impact rained back down as lava bullets. These lava bullets were able to rain back down from very far away from impact. Another thing that rained back down was extremely hot ash that spread very far and suffocated life and caused wild fires. This ash combined with rain water in the clouds and rained back down as acid. The oceans became acidic killing marine life dust from the impact blocked out the sun and caused a cold winter
