The Atmosphere Part 1 (Unit 4)
1. This is the altercation of the normal composition of air due to the presence of energy and particles, which can be harmful for living things and the environment
2. These are generated by natural phenomena, without human intervention. For example, the dust in deserts, ashes, and gases released by volcanic eruptions or the pollen produced by plants.
3. These are generated by human activity. They are classified, according to their origin, as physical or chemical.
(Natural pollutants, air pollution, and artifical pollutants)
1. air pollution
2. natural pollutants
3. artifical pollutants
The _______ _______ (two words) protects us from harmful ultraviolet rays of the Sun.
ozone layer
Give me 3 reasons why the atmosphere is so important
Regulates terrestrial temperature (greenhouse effect)
Protection against radiation and meteorites
Contains molecules that living things need
What are the consequences of destroying the ozone layer? (Tell me 2 examples)
It has negative effects on the skin, body´s defenses, and our sight. Also it reduces the efficiency of photosynthesis and loss of phytoplankton in aquatic ecosystems.
1. The _________ is the gasesous layer that surrounds the Earth.
2. In terms of the composition of air: what are two biggest components? (There are 5)
2. Nitrogen and oxygen
Lets talk about the consequences of air pollution!
What are the consequences of air pollution: at a global level, in ecosystems, or at an individual level
(choose one and explain)
*answer can be decided by teacher*
At a global level: acid rain
In ecosystems: the extinction of the species or the change of habitat
At an individual level: problems of health
The __________ ________ (two words) is the phenomena by which the atmosphere retains some of the heat from the Sun. In this way, it regulates the temperature of the Earth´s surface, maintaining temperature levels adequate for life to exist.
Greenhouse effect
Tell me 2 preventative and corrective measures of air pollution
Clean and purify the smoke and gases produced by industry.
Control and reduce emissions of toxic and dangerous pollutants.
Encourage reforestation of ancient green areas or forests.
Reduce energy consuption.
Substitute traditonal sources of energy.
Reduce the amount of residues and rubbish, and reuse and recycle both materials and energy.
What are 5 layers of the Earth´s atmosphere?
Troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
What are 2 social and economic impacts of climate change?
The cost of adapting coastal areas to rising sea levels.
Relocation of whole towns.
Shrinking productivity of harvests.
Prices of basic foodstuffs and consumer goods will rise.
Extreme meteorological phenomena will cause widespread poverty.
Diseases will spread due to higher temperatures.
Fresh water will be in short supply in some areas.
More wars to gain access to limited resources.
Loss of the capacity to work due to heat.
