21.The asteroid impact 65 million years ago in Yucatan, Mexico that caused the dinosaurs to become extinct caused this kind of damage in Hell Creek, Montana:
a.electromagnetic evacuation of oxygen from the atmosphere!
b.megatsunami waves in Montana!
c.nuclear explosion in the atmosphere!
d.Hell Creek was plunged into the center of the Earth!
Answer: b.megatsunami waves in Montana!
<<<<<<< explanation >>>>>>>>>>>>
asteriod collision with earth would have erupted a wave of combination of water air lava etc away from center of collision leading to mega tsunami

Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 5.0km and a mass of 2.5
Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 2.0 km and a mass of 1.1 ×1013 kg hits the earth (6.0×1024 kg) with an impact speed of 4.5 ×104 m/s. a. What is the earth’s recoil speed after such a collision? (Use a...
Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 5.0 km and a mass of 2.5×1014 kg hits the earth with an impact speed of 3.0×104 m/s . What is the earth's recoil speed after such a collision? Assume that the mass of the...
7- Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 2.0 km and a mass of 1.0 * 1013 kg hits the earth with an impact speed of 4.0 * 10* m/s and angle of 20 degree with x axis. a. What is the...
Most geologists believe that the dinosaurs became extinct 65 million years ago when a large comet or asteroid struck the earth, throwing up so much dust that the sun was blocked out for a period of many months. Suppose an asteroid with a diameter of 5.0 km and a mass of 2.5*10^14 kg hits the earth with an impact speed of 4.0*10^4 m/s. Part A: What is the earth's recoil speed after such a collision? Assume that the mass of...
One of the main contributing factors to the extinction of the dinosaurs 65 million years ago was a large comet or asteroid that struck the earth. It threw up so much dust that the sun was blocked for a period of many months. Suppose the asteroid had a mass of 4.0x10e13 and hit the earth (mass = 6x10e24 kg) with an impact speed of 4.0x10e4 m/s. What would be the earth's recoil speed after such a collision? (Use a reference...
1. [12 points] Compelling evidence for the asteroid impact 65 million years ago which triggered the extinction of the dinosaurs was discovery of a thin Iridium-rich clay layer in sediments all around the world. A normal rock sample from the Earth's crust contains less than 1 nanogram per gram (or 1 part per billion) of Iridium, while the Iridium clay layer associated with the K-Pg impact contains about 3 parts per billion. (a) Assume the K-T impactor was a rocky...
we've learned about the asteroid impact that occurred at the end of the Cretaceous period of Earth history, which led to the extinction of the dinosaurs. It created a crater called the Chicxulub crater, and temporarily altered the Earth's atmosphere, climate, and oceans so much that it caused a mass extinction. (You might also find it helpful to look at this geologic time scale because it shows when the Cretaceous, Tertiary, Permian, and Triassic portions of the geologic time scale...
