CP4 envi sci Atmosphere, pollution and climate

Front

What technology helps reduce particulate matter in the air?

Back

HEPA filters are designed to trap harmful particles, including dust, pollen, and smoke, improving air quality.

Front

What is the primary cause of coral bleaching?

Back

Coral bleaching is primarily caused by warmer ocean temperatures and pollutants, which stress coral and lead to the expulsion of symbiotic algae.

Front

Which greenhouse gas has the longest atmospheric lifetime?

Back

CO2 (carbon dioxide) has a long atmospheric lifetime, remaining in the atmosphere for hundreds to thousands of years.

Front

Why do biomes occur in patches along similar latitudes?

Back

Biomes occur in patches due to atmospheric circulation and north-south temperature gradients, which influence climate and vegetation.

Front

How has ocean acidity changed since the pre-industrial era?

Back

Ocean acidity has increased due to CO2 absorption, leading to harmful effects on marine life.

Front

What is particulate matter?

Back

Particulate matter (PM) consists of tiny particles or droplets in the air that can harm human health and the environment.

Front

Define greenhouse gases.

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect and climate change.

Front

What role do ocean currents play in climate?

Back

Ocean currents help distribute heat around the planet, influencing climate patterns and weather systems.

Front

Explain the greenhouse effect.

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

What is coral reef degradation?

Back

Coral reef degradation refers to the decline in health and biodiversity of coral reefs, often due to pollution, climate change, and overfishing.
