Earth's Interior
The thick layer beneath the crust where convection occurs.
The mantle
Wind, water, and ice break down rock by this process.
Weather
A push or pull on an object.
Force
a force that acts on an object without any physical contact between the objects.
non-contact forces
Differences among individuals in a species?
Variation
Which seismic waves travel through solids and liquids, and which do NOT travel through liquids
1. P-waves
2. S-waves
A river depositing sediment creates this landform.
Delta
What is the net force on an object if two forces of 10N and 6N act in the same direction? Is it balanced or unbalanced?
16 N, unbalanced
Two things gravity depends on
Mass and distance
Life forms change gradually over long periods of time
Evolution
What is convection?
Warm mantle rises, cool mantle sinks, creating a convection currents that drives plate movement
Dating rock layers without exact ages is called this.
Relative dating
In order for you to sit still on a chair, what must be happening?
a. At least one force acting on the chair is balanced
b. All of the forces acting on the chair are balanced
c. The forces acting on the chair are unbalanced
d. One of the forces acting on the chair has no mass
b. All of the forces acting on the chair are balanced
Two positive electric charges will do what?
Repel
Changes in the environment can cause this.
Natural selection
What forms at a divergent boundary between two oceanic plates?
Mid-ocean ridge
Landforms built up by deposition are caused by this.
Constructive Processes
Motion is measured based on this.
Explain how/if weight and mass change on the Moon compared to the Earth.
Mass always stays the same. Weight has to do with gravity, which is based on mass --> greater mass, greater gravitational field, higher weight
Assume that (B) is dominant and (b) is recessive: Bb mates with Bb. What is the probability of the offspring being bb?
25%
Describe one piece of evidence that supports the theory of plate tectonics.
\Matching fossils/coastlines across continents, mid-ocean ridges, seafloor spreading, or earthquake/volcano patterns along plate boundaries
Fossils found over a wide area but short time span.
Index fossils
What is acceleration?
Change in speed, direction, or both.
What is a field?
The area around an object where it can exert force without physically touching
mitosis: one division, same chromosome number, identical cells, for growth/repair.
meiosis: two divisions, half chromosome number, varied cells, for sexual reproduction.
