The climate of a place is determined by temperature, humidity, rainfall, solar radiation, wind, and atmospheric pressure over several decades. Atmospheric phenomena like storms and lightning are produced by solar radiation, temperature variation, and pressure. Climate strongly influences vegetation, animals, and humans. While climate variation exists naturally, human behavior exacerbates global warming through greenhouse emissions from daily activities and industry. The effects of warming, such as melting glaciers and rising seas, are increasingly visible. Solutions include energy efficiency and green energy.

1. Block 4 – Lesson 1

3. The climate of a place is
determined by the data
registered over several
decades. It is closely
related to temperature,
humidity, rain, solar
radiation, wind and
atmospheric pressure.

5. Atmospheric phenomena, like electrical storms,
thunder and lightning, are related to the climate
as well. They are produced as a consequence of
solar radiation, temperature variation, and
atmospheric pressure.

7. Climate has a strong
influence over the
characteristics and
distribution of
vegetation, animals,
and over people.

8. Air forms a layer around the Earth. It is a gas
impossible to touch, but possible to feel when it
moves. Earth’s rotation and revolution together
with sunlight produce wind.

9. Climate variation has always existed as a
consequence of different natural phenomena.
However, these natural phenomena only partly
explain global warming. Inadequate human
behavior is also a factor.

11. Most scientists state that global warming is
caused by an increase of greenhouse emissions
produced by human beings in their daily and
industrial activities.

13. The effects of global warming are becoming more
and more visible: the melting of glaciers, the rise
of sea levels, severe droughts, hurricanes and
floods, the extinction of plant and animal species,
and so on.

15. Some alternatives to reduce the greenhouse
effect and decrease global warming are:
• Use natural light as much as possible.
• Use energy saving light bulbs.
• Unplug all electronic devices when they are
not being used.
• Use green energy.
• Walk, use a bike or public transportation.

16. 1. What are atmospheric phenomena?

17. 1. What are atmospheric phenomena?
a) They are natural events in the atmosphere such as
storms, thunder, twisters, etc.
b) They are not natural events in the atmosphere such as
smog, contamination, acid rain, etc.

19. 1. What are greenhouse emissions?

20. 1. What are greenhouse emissions?
a) Gases produced by nature such as CO2, propane, etc.
b) Smog or hot air produced by factories, cars, houses,
etc.
