Question

Define the following

Biosphere
Global warming
Acid rain
Ozone depletion
Ecological imbalance​

Answer 1

Biosphere: All living organisms (plants and animals) make our living world or biosphere. It is the narrow zone of interaction where land, water and air interact with each other to support life.

Global warming: Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels (like coal, oil, and gas), which produces heat-trapping gases.

Acid rain: Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of elevated hydrogen ions. Most water, including drinking water, has a neutral pH level lower than this and ranges from 4-5 on average.

Ozone depletion: Ozone depletion consists of two related events observed since the late 1907: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and much a larger springtime decrease in stratospheric ozone around Earth's polar regions. The later phenomenon is referred to as the ozone hole.

Ecological imbalance: Ecological imbalance is when a natural or human-caused disturbance disrupts the natural balance of an ecosystem. A disturbance is any change that cause a disruption in the balance of an ecosystem. Examples of natural disturbances are Volcanic eruptions Floods.

ANSWER:

Hey!

===========================================

BIOSPHERE:

The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees to the dark environment of ocean trenches, to lush rain forests and high mountaintops.

===========================================

GLOBAL WARMING:

Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

===========================================

ACID RAIN:

Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms.

===========================================

OZONE DEPLETION:

Ozone depletion is the gradual thinning of Earth's ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica.

===========================================

ECOLOGICAL IMBALANCE:

Ecological imbalance is when a natural- or human-caused disturbance disrupts the natural balance of an ecosystem. The balance of an ecosystem can be disrupted by natural or human-caused disturbances. If a species disappears or a new species is introduced it can shift an ecosystem to a state of ecological imbalance.
