What is the formula for calculating force?
force = distance / time
force = velocity x time
force = energy / mass
force = mass x acceleration
What is the difference between mass and weight?
Mass is the measure of the force exerted on an object, while weight is the amount of space an object takes up.
Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity.
Mass is the force exerted on an object due to gravity, while weight is the amount of matter in an object.
Mass and weight are the same thing and can be used interchangeably.
Define the term 'momentum' in physics.
The force exerted by an object
The distance traveled by an object
The product of an object's mass and its velocity.
The temperature of an object
Describe the concept of work in physics.
Work is the product of mass and acceleration.
Work is the product of speed and time.
Work is the product of energy and velocity.
Work is the product of force and distance.
What is the difference between potential energy and kinetic energy?
Potential energy is only found in living organisms, while kinetic energy is only found in non-living objects.
Potential energy is due to position or state, while kinetic energy is due to motion.
Potential energy and kinetic energy are the same thing.
Potential energy is due to motion, while kinetic energy is due to position or state.
The explosiveness of an eruption from an active composite volcano is primarily related to which of the following?
The size and depth below the surface of the magma chamber

The El Nino-Southern Oscillation has two phases traditionally referred to as El Nino and La Nina. Which of the following is a primary factor that drives the transition from an El Nino phase to a La Nina Phase?
Variations in the frequency of sunspots over the course of a full solar cycle
Change in the circulation of deep-ocean currents that transfer heat energy from the equatorial regions to the poles
Fluctuations in the position of the polar front jet stream during different seasons
Reversal of the dominant high and low atmospheric pressure regimes on either side of the equatorial Pacific Ocean
Which of the following is the primary cause of water's high viscosity?
The low electronegativity of oxygen atoms
The high specific heat capacity of liquid water
The molecular weight of water molecules
The hydrogen bonding between water molecules
In an unpolluted aquifer, the chemical character of groundwater changes as it travels underground. Which of the following characteristics of unpolluted groundwater typically increases over time as groundwater moves through sediments and bedrock?
The proportion of bicarbonate ions
The concentration of dissolved oxygen
The proportion of suspended solids
