Science Final review Flashcards
High Humidity brings what type of weather?
Clouds and precipitation
When do tornadoes occur?
Warm moist air near the ground, with cooler dry air aloft and wind shear - a change in wind speed and/or direction with height.
What can people do to reduce air pollution?
You can drive your car less, plant trees, use less energy and more
What are the different types of weather fronts and what type of weather do each bring?
Types: Cold, Warm, Stationary, and Occluded. Cold fronts cause cumulus cloud formation and thunderstorms. Warm fronts cause gray skies and drizzle. Stationary fronts bring clouds, rain, or snow. Occluded fronts result in both warm and cold types of weather on each side of the front.
What type of clouds are there and what weather conditions do each bring?
Cirrus: Thin, feather-like, wispy clouds. A change in weather. Cirrostratus: Thin white clouds cover the whole sky. Rain or snow will happen in 24 hours. Stratus: Thin, gray-white, sheetlike clouds with low bases covering the whole sky. Fair, but gloomy., may bring drizzle or snow, Stratocumulus: Rounded cloud masses that form in a layer. they have a darkish tint. Fair weather but a storm might be on its way. Cumulus: Fluffy, white, cotton-ball clouds with flat bases and dome-shaped tops. Fair weather. Cumulonimbus: Large, dark, vertical clouds with bulging tops that can grow to towering heights.These bring showers, thunder, and lightning.
How do clouds form?
Sun heats up water and land surfaces, the warm air and water vapor rises, condensation, the condensation then makes clouds.(water cycle)
What is the best way to achieve genetic diversity?
Mutation is the best way.
Explain the differences between sexual and asexual reproduction
Asexual reproduction is performed by a single parent making a copy of themself and sexual reproduction in two parents making an offspring with shared traits.
Be able to explain the different organelles that are found in cells and what each does
Nucleus: Stores DNA
Mitochondrion: Energy Production
Smooth Endoplasmic reticulum: Lipid Production
Rough Endoplasmic Reticulum: Protein production
Golgi apparatus: Protein modification and export
Lysosome: Protein destruction
Know the levels of organization of living things
Organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, biosphere.
Know the difference between local and global wind patterns
The four types of local winds work opposite of each other. The first two are sea breeze and land breeze. Global winds are the polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums. Polar easterlies are dry, cold prevailing winds that blow from the east. They emanate from the polar highs, areas of high pressure around the North and South Poles
Know why pressure changes as you go higher in the atmosphere
With fewer air molecules above, there is less pressure from the weight of the air above.
Be able to explain the different atmospheric layers and characteristics of each layer
The Troposphere-lowest part of the atmosphere ,the part we live in. It contains our weather. The temperature gets colder as the distance above the earth increases. The Stratosphere- contains much of the ozone in the atmosphere. The Mesosphere-above the stratosphere, temperature again decreases with height. The thermosphere-temperatures again increase with height.contains auroras.The Exosphere-contains satellites
