Understanding Climate Change

The video explains climate change, starting with the greenhouse effect, where greenhouse gases trap heat in the atmosphere. Human activities, like burning fossil fuels, increase carbon dioxide levels, leading to global warming and climate changes. Visible signs include rising temperatures, melting ice, and shifting wildlife patterns. If unchecked, climate change could cause severe weather, disease spread, and ecosystem damage. However, solutions exist, such as using renewable energy and reducing personal energy consumption, to mitigate these effects.

What is the primary role of greenhouse gases in the Earth's atmosphere?

• To cool the Earth's surface

• To increase the Earth's rotation speed

• To trap heat and keep the planet warm

• To block sunlight from reaching the Earth

What is the greenhouse effect?

• A process where the Earth loses heat to space

• A process where greenhouse gases trap heat in the atmosphere

• A process where the Earth absorbs more sunlight

• A process where the atmosphere becomes thinner
