Total questions: 20

What is the source of the thermal energy that heats our planet’s atmosphere?
Earth's core
Green plants
The Sun
Fossil Fuels
The Sun warms the atmosphere and drives convection currents because -
warm air is less dense, so it rises.
the warmed air cools and makes rain.
the cooler land pushes away warm air.
warm air, in contact with cool air, rotates.
What is one effect of the uneven heating of Earth caused by the Sun?
Rotation of Earth
Generation of wind
Oceans losing salt
Plants failing to grow
An illustration of how a convection current creates a wind, called a land breeze, is provided.Which of the following best explains what creates this convection current?
The rotation of Earth makes the air above it rotate, but not the same over land and water.
Because of its mass, Earth’s gravity creates a high pressure area over both the land and water.
Salt in the ocean makes it more dense than the land, so its gravity pulls more on the air above it.
During the evening, the land cools off more quickly than the water, so the air is different temperatures.
Convection is the type of heat transfer that occurs in which of the following?
Empty space
Solid materials
Liquids and gases
Objects in contact
The illustrations show the usual wind pattern at the shore during the day and night.What is the most important factor that creates these wind patterns?
Most people visit the shore during the day and are not there at night.
The air above the land heats up and cools off more quickly than the air over the water.
The seawater is capable of having salt dissolved in it, but the land cannot.
The shape of the land is constantly being changed by the motion of the seawater.
What is a type of energy that spreads out as it travels?
Radiation
Conduction
Convection
Electrical
What is the process by which heat is transferred through direct contact?
Radiation
Conduction
Convection
Boiling
Differences in density create differences in air
temperature
pressure
luminosity
quality
Air pressure at the Earth's surface is _______ than higher up in the atmosphere
higher
lower
The higher you rise into the atmosphere, the _________ the air pressure becomes.
higher
lower
Which of the following affects surface ocean currents?
wind
tides
differential heating of sea water
all of the above
Sabrina noticed a lot of puddles on her driveway after it rains on Tuesday afternoon. On Wednesday morning she notices the puddles are gone. Why?
The wind blew the puddles away
They disappeared
The suns energy caused the water to evaporate
The suns energy caused the water to precipitate
Where does energy that heats the land, water, and air come from?
Batteries
Lamps
The sun
The moon
Andres goes to the beach on Saturday. Andres notices that the sand at the beach is hot but the water in the ocean is too cold to swim in. Why?
Land heats up faster than water
Water heats up faster than land
Andres used a lamp to heat up the sand
Alondra records the temperature in the shade under the tree and outside in the sun. Which temperature would be higher?
In the sun
In the shade
Both temperatures would be the same because both are outside
Sea Breeze occurs during what time of day?
Day Time
Night Time
When sea breeze occurs, cold air sinks over the land or sea?
Land
Sea
Land Breeze occurs during what time of day?
Day Time
Night Time
Below the surface, deep ocean currents are driven by differences in ________________. Specifically, it is due to the differences in temperature and salinity.
Density
Convection
Particles
Fish
