Gravity
As objects move away from each other what is happening to the gravitational force? (Increasing or Decreasing)
Decreasing
3rd law
What are the three types of rocks?
Igneous, Sedimentary, Metamorphic
The continents were once all connected in a supercontinent known as what?
Pangea
What do the H and the L symbols stand for on the weather map?
High and Low pressure areas
High pressure areas are formed when cold dense air is sitting close to the surface, and low pressure areas are formed when hot air rises away from the surface.
What two factors effect gravity?
Mass and Distance
What is Newtons first law?
An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an outside force.
What do you call a scientist who studies rocks?
Geologist
Before the theory of plate tectonics what was the theory that we believed was responsible for the movement of the continents?
What are the four types of fronts that you may find on a weather map?
Warm front, cold front, stationary front, occluded front
How do you calculate the force of gravity between two objects?
Multiply their masses
Newtons second law states F= M x A.
What does F=M x A stand for?
Force = Mass x Acceleration
What is the type of rock that forms when molten magma from within Earth cools and solidifies?
Igneous
Who proposed the idea of continental drift?
Alfred Wegener
The first letter in our abbreviations (cT, mA, cP, etc.) tells us about what?
Formed over land or see which determines the amount of moisture
If the force of gravity between two objects id 48 units and the mass of object X is 4 units, what is the mass of object Y?
12 units
If a cart strikes a wall with a force of 5 Newtons.
What is the force the wall exerts on the cart?
5 Newtons
When sediment is moved by wind or water and dropped in a particular spot, what two processes are happening?
Transport and deposition
What is the driving force behind the movement of our tectonic plates?
Convection currents in the mantle
Areas of equal air pressure
What will the force of gravitational attraction between the objects be if the mass of both objects doubles?
32 units
Which ball will strike a wall with the most force?
A. 5 g ball accelerating at a rate of 4 m/s2 eastward
B. 10 g ball accelerating at a rate of 1 m/s2 eastward
C. 15 g ball accelerating at a rate of 3 m/s2 eastward
D. 20 g ball accelerating at a rate of 1 m/s2 eastward
C. 15 g ball accelerating at a rate of 3 m/s2 eastward
What is the type of rock that forms when heat and pressure beneath the Earth's surface is applied to an existing rock?
Metamorphic
What evidence do we have to support the idea that are continents were once joined?
The coast lines of Africa and South America line up, or fossil records/ rock records
