The Big Bang Theory and Its Cosmic Implications

Big Bang

Theory describing the universe's formation 13.8 billion years ago.

Universe Expansion

The universe continues to grow from a single point.

Doppler Effect

Change in frequency due to relative motion of source.

Blue Shift

Increase in frequency as objects move closer.

Red Shift

Decrease in frequency as objects move away.

Evidence of Expansion

Red shift indicates galaxies are moving away, supporting Big Bang.

CMBR

Cosmic Microwave Background Radiation, leftover from Big Bang.

Star Formation Stages

Processes leading to the birth of stars.

Nuclear Fusion

Process where hydrogen atoms combine to form helium.

Carbon Cycle

Processes and storage of carbon in Earth's systems.

Excess Carbon Dioxide

Leads to global warming through greenhouse effect.

Greenhouse Gases

Gases that trap heat in the atmosphere.

Greenhouse Effect

Process where greenhouse gases warm the Earth's surface.

Global Warming Impact

Consequences of rising global temperatures on ecosystems.

Earth's Spheres

Atmosphere, hydrosphere, lithosphere, and biosphere interactions.

Carbon Reuse

Carbon is constantly cycled through Earth's spheres.

Individual Actions

Steps to reduce greenhouse effect at personal level.

National Actions

Australia's strategies to combat greenhouse gas emissions.

Global Actions

International efforts to mitigate climate change.

Earth's Spheres Interaction

How different spheres affect each other and the environment.
