Environmental Science Quiz - Climate Change

The human heart can generate enough pressure to squirt blood much farther than 1 foot - up to 30 feet or more. Normal systolic blood pressure can reach around 120 mmHg, which is sufficient to propel blood vertically against gravity. The '1 foot' distance is a significant underestimate, making the False statement correct.

Carbon dioxide is the primary greenhouse gas responsible for global warming through the greenhouse effect. It traps heat in the Earth's atmosphere by absorbing infrared radiation. While other gases like methane and water vapor also contribute, CO2 from burning fossil fuels is the main driver. Nitrogen is inert and noble gases do not trap heat.

The ozone layer in the stratosphere absorbs most of the Sun's harmful UV radiation. When this layer is depleted by chemicals like CFCs, more UV rays reach Earth's surface. Oxygen, carbon dioxide, and clouds do not perform this protective UV-filtering function.

The greenhouse effect is the process by which certain gases trap heat in the Earth's atmosphere, causing global warming. Gases like CO2 and methane act like glass in a greenhouse, letting sunlight in but preventing heat from escaping. There is no scientific concept called 'White House', 'Blue House', or 'Red House' effect.

Chlorofluorocarbons (CFCs) are synthetic chemicals that both deplete the ozone layer and contribute to global warming as potent greenhouse gases. They were used in refrigerants and aerosols before being phased out by the Montreal Protocol. Nitrogen dioxide and ammonia do not have this dual impact.

Microsoft developed Worldwide Telescope, a software program that enables users to explore the universe through astronomical imagery and data from telescopes worldwide. Google has Google Earth/Google Sky for earth and sky mapping, IBM is primarily an enterprise technology company, and Oracle focuses on database software and cloud services.

India signed the agreement to procure Advanced Jet Trainer (Hawk) aircraft from the UK (British Aerospace) in 2004. The deal was worth over $1 billion and involved 66 aircraft. The other countries listed did not supply the Hawk trainer to India.
