A balanced object has a net force of this.
Zero (0)
This type of seismic wave arrives first after an earthquake
P-Wave
The maximum stress a material can withstand before permanent deformation is known as this
Elastic Limit
This type of crust is the most dense
Oceanic Crust
Outer Core
A vector always provides these two pieces of information
1) Direction
2) Magnitude (or quantity)
This type of wave moves in the above pattern
S-wave
The reason that some matter sink while other matter floats is because of this property
Density
This process provides the heat necessary for convection currents in the mantle
Radioactive Decay
New oceanic crust is created at this type of boundary
Divergent Boundary

As matter becomes warmer, waves move ___________
Slower
This is where energy is stored in an atomic nucleus
In the Mass
This force holds an atomic nucleus together
The Strong Force
Convection currents can be found in this layer of the Earth
Mantle
Provide the net force on this system (give both direction and magnitude)
4N to the right (East)
What type(s) of matter can this wave move through?
Solid, Liquid, and Gas
(P-Wave)
This force tries to push protons apart in the nucleus
Electric Force
or Electrostatic Force
These occur in the mantle and pull tectonic plates in different directions
Convection currents
Oceanic crust is destroyed at this type of plate boundary
Convergent Plate Boundary
Draw the following as a free body diagram:
A rock falls towards Earth. Gravity is pulling with 100N of force. Wind resistance pushes back with 5N of force.
See the board
Waves move at different speeds as they travel through Earth, providing evidence that our world is _____________
Heterogenous
Losing (or gaining) these cause elements to change their physical properties
Protons
When Elements breakdown during radioactive decay they create these two things
1) New stable element
2)HEAT
