Study Notes
Water Cycle
- The water cycle is a continuous process of evaporation, condensation, precipitation, and collection.
- Rain falls in a slight right direction due to Earth's rotation.
Plant Biology
- Chlorophyll gives plants their green color. It absorbs blue and red light, reflecting green.
- Plants die when watered with salt water; osmosis causes a loss of water.
Earth Science
- Central Valley, California, is colder in the winter than the coast due to the warmer temperatures of the central coast.
- The ocean freezes at lower temperatures than lakes due to the salt content.
- A barometer measures air pressure/atmospheric pressure.
- Polaris, the North Star, is the direction that Earth is pointed, and stars circle around it.
- The open ocean has less productivity than the continental shelf due to a lack of nutrients from land or ocean sediment.
Evolution
- Natural selection is a process that leads to adaptations that help organisms survive, including variation, overpopulation, competition, and reproduction.
- Mutations cause variations in organisms and can be beneficial or harmful.
Geology
- Frost weathering is a form of physical weathering where ice crystals form in granite, breaking it down.
- The winter solstice in the Northern Hemisphere is when the North Pole is tilted farthest away from the sun.
Cell Biology
- The nucleus is the control center of a cell; it contains chromosomes made of DNA.
- DNA replicates RNA.
- Photosynthesis uses carbon dioxide and water to create glucose (sugar) and oxygen.
- Cellular respiration uses glucose and oxygen to create energy.
- The function of a cell is determined by its structure; for example, muscle cells are long and tubular.
Chemistry
- Protons and neutrons are found in the nucleus of an atom.
- The pH scale measures acidity; lower numbers indicate higher acidity.
- Lemonade (pH 2.3) is the most acidic out of the listed options.
Natural Disasters
- The Loma Prieta Earthquake of 1989 caused more damage near San Francisco Bay due to the presence of sediments and fill near the shoreline.
Ecology
- El Niño disrupts the food chain by altering ocean conditions.
- Fungi are decomposers.
Oceanographic
- The Sunlit Zone, also called the euphotic zone, is the top layer of the ocean where sunlight penetrates and supports the most ocean life.
Antarctica
- Antarctica, particularly the Ross Ice Shelf, experiences the longest amount of sunlight during the winter solstice in the Northern Hemisphere.
