What is the fossil record?
A record of all the known fossils in the world.
Layers of Earth with fossils in chronological order.
A record of fossil songs.
Layers of Earth that records time in geographical order.
What causes species to change over time?
Changes in their mood.
Changes in their environment.
Changes to the moon.
Changes to their body.
Evolution is
the changes that happen to an organism over a short period of time.
Changes that happen in the environment.
when species die off completely.
change in the characteristics of a species over several generations
The Law of Superposition states
The layers of earth get younger as we go deeper in the Earth.
The layers of earth get older as we go deeper into the Earth.
The layers of earth change color as we go deeper into Earth.
The position of layers depends on the super of the layers.
You are studying the fossil record and suddenly 75% of the fossils vanish from the fossil record. What does this mean?
There was an earthquake.
Lots of babies were born.
There was a mass extinction.
Evolution caused them to die off slowly over time.
The mineral that is commonly found in asteroids and is found in large amounts in the layers of Earth dated at 65 million years ago is called
Carbon
Iridium
Platinum
Kryptonite
The three pieces of soil evidence for an asteroid collision 65 million years ago are
high amounts of Iridium, lots of soot, and pressurized quartz crystals
high amounts of kryptonite, lots of soot and diamonds
Low amounts of Iridium, kryptonite and soot.
Millions of dead animals, a giant crater, volcanoes.
How many mass extinctions have happened in the past?

A force is
up or down motion
wave
magical powers
a push or pull
Newton's 1st Law states
all forces have an equal and opposite reaction
objects do not move without being affected by a force
Force = Mass x Acceleration
Mass + Force = Density
Force = Mass x Acceleration is the formula associated with which Law of Motion?
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
Newton's 4th Law
When you jump into a pool water splashes up because of which Law of Motion?
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
Newton's 4th Law
You push your sister into the pool. This is an example of
a balanced force
an unbalanced force
Newton's 3rd Law
Inertia
Kinetic energy is the energy of
excitement
motion
gravity
waiting to move
More mass equals
less energy
less gravitational force
more energy
less speed
Force = Mass x Acceleration. Solve this equation for Force.
F = 5kg x 20 m/s
20 Newtons
5 kg
100 Newtons
100 kg/m/s
When a cannon fires the cannonball goes forward and the cannon flies backward. Why is this?
The cannonball is light.
The weight of the cannon is too heavy.
Newtons 1st Law states that things move when acted on by a force.
Newton's 3rd Law states that every action has an equal and opposite reaction.
An object that is close to earth is called a
Near Earth Object or NEO
Close Earth Object or CEO
Unidentified Flying Object or UFO
Identified Flying Object or IFO
Preventing an asteroid collision is important because
It could cause a mass extinction.
They are interesting to research.
It has minerals we can mine for money.
We don't need to study asteroids.
Asteroids hit earth or its atmosphere every
day
week
year
millennium
