Major environmental issues today

Resources (mdc v LDC

Mdc- more developed countries

Ldc- less developed countries

Environmental ethics

Scientific method

A step by step process scientist use to answer questions

Variables

Something that can be changed or measured in a experiment

What major factors influence climate? How?

The sun and the shape of the earth, uneven heating, more direct rays near equator bc the earth is tilted on a 23.5 degree angle

Climate vs weather

Weather-What the atmosphere is like rn

Climate- weather patterns over a long period of time

Layers of atmosphere

Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere.

Ozone

A gas that protects earth from the suns harmful uv rays

Carbon cycle

The natural process where carbon moves between the atmosphere

Systems(pools-fluxes)

Pools-places where matter is stored(ocean, forest)

Fluxes- the movement of matter or energy between pools

Greenhouse effect

The process where gases in Earth’s atmosphere trap heat from the Sun, keeping Earth warm enough for life.

GHGs (CO2e)

A way to measure the warming effect of different greenhouse gases using the equivalent amount of CO₂.

Evidence of climate change

Rising sea levels, rising temperatures,melting glaciers

Human influence on climate change

Factories and power plants, cutting down trees

Category’s of pollution

Air, water, land ,noise, light

Primary vs secondary pollution

Primary- released directly

Secondary- forms afterwards

Clean air act

rules to reduce air pollution and protect people’s health and the environment.

Montreal protocol
