Worksheets7.2 Weather and climate
Total questions: 12
Worksheet time: 6mins
What is climate?
short term variation in temperature and precipitation
the interaction between atmosphere and hydrosphere
the amount of terrestrial radiation emitted by a region
Long- term weather patterns
The main reason temperature decreases from Equator towards the pole is:
Sunlight is spread over a larger area over higher altitude
convection cells distribute heat from the Equator towards the poles
the Earth is tilted on its axis
there are more heat trapping clouds near the Equator
The ocean conveyor belt is a world-wide system of:
warm surface currents and atmospheric convection cell
cold surface currents and atmospheric convection cell
cold surface currents and warm deep currents
warm surface currents and cold deep currents
The Gulf Stream is a section of the ocean conveyor belt that is:
transports cold water from the North Atlantic to the South Atlantic
plunges cold salty water straight down to the ocean floor
transports heat from the Equator towards Europe
circulates warm water around the Indian Ocean from the Persian Gulf
Earth's atmosphere allows all wavelengths of the Sun's radiation to pass through to the planet's surface
True
False
Which of the following claims about greenhouse gases are true? (more than one options are correct)
Greenhouse gases absorb infrared radiation
Water vapour is greenhouse gas
Greenhouse gases emit infrared radiation
Greenhouse gases make up 20% of Earth's atmosphere
The effect of greenhouse gases in Earth's atmosphere is to:
absorb ultra-violet and other high-energy radiation from the Sun, protecting the Earth's surface
retain some of the heat emitted from the Earth's surface
trap heat in the lower atmosphere so that no one can excape into space
reflect sunlight back into space
Does the greenhouse effect change the energy budget of the entire planet? That is, does it change the amount of energy received by and emitted by the planet?
Yes
No
The best description of global warming is:
an increase in the average world temperature
greenhouse gases in the atmosphere
a period that began after the Industrial Revolution
periods during which sea levels fall, exposing more land.
Sustainable ecosystems are:
ecosystems that provide many different resources for humans
stable ecosystems that have survived unchanged for thousands of years
diverse ecosystems that provide for the needs of the organisms that live in them
ecosystems that survive without any input from humans.
The statement that does not describe an effect of Antarctic ice is:
Ice acts as an insulator, reducing the amount of heat that moves from the water into the atmosphere.
As the ice freezes, salt remains in the ocean, increasing the salinity and density of the water.
Cold, dense water at the Antarctic takes carbon dioxide from the atmosphere and carries it into the deep ocean currents
Areas of ice reflect more of the Sun’s rays than forests. This has the effect of increasing Earth’s average temperatures.
Which of the following options is an unlikely effect of global warming?
Plants found on mountain tops will extend their range towards the lower slopes and valleys.
Winters will become shorter in many places, so that the growing season will increase.
Melting ice will cause sea levels to rise, inundating low-lying areas.
Animals found in warm seas will extend their range away from the equator and towards the poles.
