2. Infer the beneficial and harmful effects
of changes that happens in the environment
3. - The heat
of the sun provides energy
to make the water cycle
work. The sun evaporates
water from the oceans into
water vapor. This invisible
vapor rises into the
atmosphere, where the air
is colder. The colder air
causes water vapor to
condense into water
droplets and clouds.
7. - Pollution is the introduction of contaminants into
the natural environment that cause adverse change. Pollution
can take the form of chemical substances or energy, such as
noise, heat, or light. Pollutants, the components of pollution, can
be either foreign substances/energies or naturally occurring
contaminants.

9. 2. Climate Change – is a change in global or regional climate patterns, in particular a change
apparent from the mid to late 20th century onwards and attributed largely to the increased
levels of atmospheric carbon dioxide produced by the use of fossil fuels.
The primary cause of climate change is the burning of fossil fuels, such as oil and
coal, which emits greenhouse gases into the atmosphere—primarily carbon dioxide. Other
human activities, such as agriculture and deforestation, also contribute to the proliferation
of greenhouse gases that cause climate change.

10. 3. Food spoilage- is the process of change in the physical and
chemical properties of the food so that it becomes unfit for
consumption. Food spoilage is any undesirable change in food. ... The
main cause of food spoilage is invasion by microorganisms such
as fungi and bacteria.
11. 4. Acid rain - is a rain or any other form of precipitation that is
unusually acidic, meaning that it has elevated levels of hydrogen ions.
It can have harmful effects on plants, aquatic animals, and
infrastructure.
Acid rain is caused by a chemical reaction that begins when
compounds like sulfur dioxide and nitrogen oxides are released into the air.
These substances can rise very high into the atmosphere, where they mix
and react with water, oxygen, and other chemicals to form more acidic
pollutants, known as acid rain.
