Lecture Notes Review: Tides, Fusion, Radiation, Photosynthesis, EM Spectrum, Ozone Layer

Seven flashcards covering Spring Tide, Neap Tide, Nuclear Fusion, Solar Radiation, Photosynthesis, the Electromagnetic Spectrum, and the Ozone Layer.

What is a Spring Tide?

A tide with the greatest difference between high and low water, occurring during full moon and new moon phases; produced when the Earth, Moon, and Sun align in a straight line, pulling water in the same direction.

What is a Neap Tide?

A tide with the least difference between high and low water, occurring during the first and third quarter moon phases; the Sun's gravity partially opposes the Moon's, making tides less extreme.

What is Nuclear Fusion?

The process by which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy; powers the Sun and stars and occurs under extreme heat and pressure.

What is Solar Radiation?

Energy emitted by the Sun as electromagnetic waves (visible light, infrared, and ultraviolet); warms Earth, powers photosynthesis, and drives weather and climate; intensity is greatest near the equator.

What is Photosynthesis?

The process by which green plants and some organisms use sunlight to synthesize foods with chlorophyll; they take in carbon dioxide and water, use energy to produce glucose, and release oxygen.

What is the Electromagnetic Spectrum?

The range of all possible frequencies and wavelengths of electromagnetic radiation, from radio waves to gamma rays; waves differ by wavelength and frequency; ultraviolet radiation can cause skin cancer with prolonged exposure.

What is the Ozone Layer?

A region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation; contains ozone (O3) and protects living things from UV damage; depletion linked to greenhouse gas emissions.
