Physics
Inertia is the act of...
BEING LAZY!!
Explanation: An object is in a state of rest before being forcefully moved, not stopping until another force stops it.
How often does the total energy change?
NEVER!!
Explanation: the total engery is the total amount of engery combined, potentioal, thermal, kinitec.
What was the supercontinent on Earth, a long time ago, called
PANGEA!!
Supercontinet is when all the continents were combined once in the universe and might happen again.
What are the different plate boundaries called
Divergent, Convergernt, Transform
What is the downhill movement of Earth material caused by gravity?
MASS WASTING!!
What doesn't change when going to another planet's gravity?
You're mass.
An object has the most potential energy when it's on the floor. True or False?
FALSE!!
Explanation: potential energy is the energy that could turn into kinetic energy.
Ex: when a rock is on the edge of a cliff and is about to fall, it has the most potential engery
What are the four layers of Earth called?
1) CRUST (the out most, the one we live on)
2) MANTLE (the hot molten one)
3) OUTER CORE (the one that is composed of molten iron and nickel)
4) INNER CORE (the one that stores all the Iron that creates our magnetic feild
What is Slab Pull and Ridge Push
Slab Pull: force produced by the sinking of a plate
Ridge Push: consequences of the rising mantle of an ocean ridge.
What are the four types of mass wasting?
Creep, Earthflow, Mudflow, Rockfall
What happens to the molecules when liquid is frozen?
Its molecules move more slowly.
Explanation: the molecules are being squished into a area and not having the free moving space they have when they are a liquid.
Define Thermal Equilibrium
When objects come together and end up with the same temperature.
A theory named after a famous scientist named...
Wegners Theory
How does the vertical movement of water in a deep part of the ocean become the massive tsunami waves that reach land?
As the waves reach land, they slow down and get taller and compress.
When something is compacted Ex: Trash what changes?
DENSITY!!
Explanation: when something is more compact it is more dense
What does it take for an airplane to fly
The force of lift and thrust to overcome the force of weight/gravity and drag.
Name are the four types of volcanos.
Convergent, Divergent, Explosive, Nonexplosive.
What makes an atom look solid on the outside?
THE NUCLEUS!!
Explanation: The nucleus of an atom guides electrons that wizz around at light speed, making the object look solid on the outside.
Define Thermal Energy
The energy of an object or system from kinetic energy of the moving, vibrating, or rotating atoms and molecules of the object.
First signs of life on Earth (Hint: there are two.)
STRAMATOLITES AND BACTERIA
Explanation: Stramatolitizes brought oxygen that helped bacteria form. On early Earth.
How large was the tsunami that struck Japan on March 11, 2011?
3-38 meters tall
