How do we know that major extinctions have happened in Earth’s history?

• Cave paintings from billion year old humans showed it.

• Plentiful fossils of ancient organisms are NOT found in younger rock layers.

• There is no real evidence that extinction events have ever happened on Earth.

Physical evidence in rock that proves ice ages have occurred on various continents over Earth’s 4.6 billion year old history.

• Radiometric Dating

• Impact craters

• Striations (scratches) in rock and Moraines.

Which is NOT a way ocean basins can help provide evidence of Earth’s amazing history? (3 are correct, find the one that is wrong!)

• Ocean floors hold the fossils of ancient once living ocean organisms that scientists can study.

• There are divergent boundaries that continually create new rock from cooled magma.

• By the way ocean water currents heat and cool the Earth’s atmosphere and the land around them.

Which best describes relative dating of a rock/fossil in a rock layer? ​​​​​​​

• Using radioactive decay to find the age of a rock.

• Using index fossils to determine the exact age of items in the same layer.

• Determining if rock/fossils are older or younger based on how deep the rock layers are.

Which two major Earth events have given scientists evidence of major extinctions several different times during Earth’s long history with the special rock layers they created?

• Mountain building and Radiometric Dating

• Meteorite impacts and Significant Volcanic Eruptions

• Index fossils and Carbon 14 dating

Why a ball falls to the ground?

• Earth's force of gravity is GREATER than the ball's, so the ball gets attracted to the ground. 

• Earth's force of gravity is LESS than the ball's, so the ball gets attracted to the ground.
