Answer:

polar easterlies,southeast trade winds,northeast trade winds|westerlies

6

Classify each scenario based on the speed and strength of the weather it would likely produce.

Answer:

a cold, dry air mass pushing into a warm, humid air mass|two air masses with similar temperature and humidity meeting at a stationary front,a warm, humid air mass gradually moving over a cold, dry air mass

What conclusion can be made based on the pattern in the graph?

A
Sea level changes have increased while nitrous oxide has decreased.
B
Both nitrous oxide and sea level changes have decreased.
C
Seal level changes have decreased while nitrous oxide has increased.
D
Both nitrous oxide and sea level changes have increased.

Based on the scenario, which question can be answered correctly about how methane affects the Earth’s climate by looking at its shape, and how it absorbs energy?

A
How does having four bonds increase the amount of heat energy absorbed?
B
If you change a bond to a double bond, will that change the amount of heat energy absorbed?
C
Why does the increase in temperature affect the Earth's climate?
D
Can any four-bond molecule absorb more heat energy than methane?
13

Why is atmospheric pressure highest in the troposphere?

A
The troposphere contains greenhouse gases like water vapor and carbon dioxide that exert strong atmospheric pressure.
B
Gravity pulls air molecules toward Earth's core, and the force of gravity is stronger closer to the planet’s surface than it is farther away.
C
The other layers contain the same number of gas particles, but they press down on the troposphere, reducing the volume of the troposphere.
D
The troposphere contains the ozone layer, which is a concentrated layer of gas that exerts atmospheric pressure.
14

Which term best describes liquid behavior under pressure?

A
immiscible
B
compressed
C
incompressible
D
surfactant
15

When the process of condensation occurs, the kinetic energy of particles

A
is insufficient to overcome intermolecular forces.
B
becomes independent of temperature.
C
becomes exactly equal to the intermolecular forces.
D
easily overcomes the intermolecular forces.
16

Which best characterizes a crystal?

A
a loose association of particles moving past one another
B
a number of high speed particles moving randomly
C
a high-energy state of matter made up of a swirling, ionized gas
D
a dense substance that is hard and incompressible
17

Which statement describes effusion?

A
It occurs when gas molecules disperse throughout a container.
B
It occurs when a liquid disperses throughout a container.
C
It occurs when a liquid passes through a tiny hole.
D
It occurs when a gas passes through a tiny hole.
18

Place the zones of Earth in order of the angle at which sunlight strikes the surface. Place the zone where the angle of sunlight is highest (sunlight is most intense) at the top of the list and the zone where the angle is lowest (sunlight is most indirect) at the bottom.

Which is a postulate of the kinetic-molecular theory?

A
Gas particles are very large in size and always move slowly.
B
Gas particles have a large volume relative to the spaces between them.
C
Gas particles have a small volume relative to the spaces between them.
D
Gas particles are very small in size and always move slowly.
20

Why do amorphous solids not have a long-range order in the arrangement of their particles?

A
Their formation involves very rapid cooling.
B
Their particles eventually change positions.
C
Their particles always stay in the same positions.
D
They do not have enough particles.
