Where is Chicxulub, Mexico, on Mexico's Yucatan Peninsula.
The Alvarez's were studying historic marine animals in Italy when they discovered this layer in the earths fossil record?
What is the iridium anomaly?
Our brains interpret this kinetic energy as waves that are caused by the vibration of particles in a medium, such as steel, water, or air.
What is sound energy?
A crane uses 20N of energy to move a steel beam 10m. How much work did the crane do?
What is 200 Joules of work/
A rollercoaster at the top of the highest drop on the track is an example of which classification of energy?
What is potential energy?
After the asteroid crashed down to earth, dinosaurs felt the atmosphere rapidly heat up due to this intense energy radiating from falling debris and fire.
What is thermal energy.
These physical debris were found around the Yucatan Peninsula that helped scientists confirm the asteroid impact was near Chicxulub.
Hint: Houston, Haiti, and The Gulf of Mexico are where you can find these physical debris.
Shocked quartz, glass spheres, and tsunami debris
The potential energy stored in chemical bonds of substances.
What is chemical energy.

What is 1,500 Joules
Pepper the caterpillar is taking aim with a rubberband and foam ball.
What classification and form of energy is at play here?
Potential energy in the form of elastic energy.
Kinetic energy transferred directly into the water of the Gulf of Mexico instantly created these large displacement waves.
What are tsunamis?
In the 1970s, before the discovery of the iridium anomaly, this scientist was searching for oil drilling locations and while doing so, found magnetic waves that indicated a large collision happened off the Yucatan Peninsula. Who is the scientist?
Who is Glen Penfield?
The larger the mass the greater the ____ potential energy.

What is 400 Joules
A microwave heats your food using magnetic waves to control electrons. This is what form of energy?
What is electromagnetic energy?
When the asteroid hit earth, this type of mechanical energy tore through the Earth's surface, creating extreme shifting in the Earth's crust.
