moon phases #RockinReview
A waxing moon is when the moon is part light and is moving towards a full moon
A waning moon is when the moon is past full and moving towards a new moon
A gibbious moon is when the moon is more than half light but less than fully light
A cresent moon is when the cycle is between half moon and new moon
The lunar cycle refers to the moons continuous orbit around the earth and is 29.5 days long
Earth's Seasons/Eclipses #eclipses
3. Copernicus was a scientist in the 1400's who first thought the idea that the sun was at the center of the galaxy and not earth
4. we have seasons because the earth is tilted (wonky) as it makes its yearly journey around the sun. The Earth's axis is tilted at an angle of 23.5 degrees. This means that the Earth is always "pointing" to one side as it goes around the Sun.
5. During the summer, the sun's rays hit the Earth at a steep angle. The light does not spread out as much, thus increasing the amount of energy hitting any given spot. Also, the long daylight hours allow the Earth plenty of time to reach warm temperatures.During the winter, the sun's rays hit the Earth at a shallow angle. These rays are more spread out, which minimizes the amount of energy that hits any given spot. Also, the long nights and short days prevent the Earth from warming up.
6. If the Moon happens to be too far from Earth for its disk to completely hide the Sun, an annular eclipse occurs. Because the Moon's orbit around Earth is slightly inclined with respect to the ecliptic, solar and lunar eclipses do not occur every month, but only a few times per year.
8. because earth rotates so sun only hits half of earth at at time
10. The days are longer around the summer solstice and shorter around the winter solstice. When the Sun's path crosses the equator, the length of the nights at latitudes +L° and -L° are of equal length. This is known as an equinox.
Plate Tectonics #platetectonics
Alfred Wegener was known for his thoughts on continental drift which is the gradual movement of the continents across the earth's surface through geological time.
convergent- tectonic plates move toward one another and collide.
divergent- a linear feature that exists between two tectonic plates that are moving away from each other
transform- when two plates slide past each other horizontally (it wont let me put in pictures)
the juan de fuca tectonic plate is just of the coast of Washington and it feeds the volcanos and has caused some great earthquakes
convection currents- a current in a fluid that results from convection
convection currents are what move the plates
A rift zone is a feature of some volcanoes, especially shield volcanoes, in which a linear series of fissures in the volcanic edifice allows lava to be erupted from the volcano's flank instead of from its summit
A subduction zone is when a collision between two of the planet's tectonic plates When two tectonic plates meet, one may slide underneath the other, curving down into the mantle
The channeled scablands are a barren, relatively soil-free landscape in eastern washington, formed by a flood unleashed when a large glacial lake drained
Rocks and Roles #RocksAndRoles
sedamentary rocks are types of rock that are formed by the deposition of material at the Earth's surface and within bodies of water. sandstone is an example of this
metamorphic rock is rock that was once one form of rock but has changed to another under the influence of heat, pressure, or some other agent without passing through a liquid phase. marble is an example of this
Igneous rock is formed through the cooling and solidification of magma or lava. granite is an example of this
stratification is a system of layers, classes, or categories. stratification is used to describe a way of arranging geological layers of rocks
more layers means its older rock
the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell
a few additional structures found in plant cells include chloroplasts, the cell wall
cell wall- a rigid layer lying outside the plasma membrane of the cells of plants, fungi, and bacteria
chloroplast-Their main role is to conduct photosynthesis
centriole-occurring in pairs and involved in the development of spindle fibers in cell division
bone cells-to help you grow
nerve cells-Your nervouse cell contains millions of nerve cells, called neurons. Neurons are highly specialised to transmit messages from one part of your body to another
muscle cells-cause contractions that changes both the length and the shape of the cell,uscle function to produce force and motion
just green/yellower green/just yellow
can be herterozyguos and asexual will always be homozyguos
evalution; process of formation or growth; development
species; a class of individuals having some common characteristics orqualities
gene; the basic physical unit of heredity
genetic;of, relating to, or produced by genes
sexual reproduction; doing "it"
asexual reproduction; reproduction, as budding, fission, or spore formation, not doing "it"
Give 5 types of ecosystems and describe each.
Define the following by using them in a sentence.
1. decomposer- a decomposer is an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
2. consumer- a consumer is a person or thing that eats or uses something
3. ecosystem- an ecosystem is a biological community of interacting organisms and their physical environment.
4. producer- a producer is a an organism that make stheir own energy
5. food chain- a food chain is a series of organisms each dependent on the next as a source of food
6. biotic- biotic means resulting from living things, especially in their ecological relations
7. abiotic- abiotc means physical rather than biological; not derived from living organisms
8. adaptation- adaptation is when something changes with enviorment to survive
9/10. What are some examples of biotic factors in a wetland ecosystem?What are some abiotic factors in a wetland ecosystem?- Abiotic factors are sunlight, air, climate, soil, water, rocks, and temperature. Biotic factors are turtlehead flowers, water, trees, butterflires, competition, bacteria, carrying capacity, plaintain, ash, and the false foxglove.
11. Find an example of a wetland ecosystem food chain:
Producer->Primary Consumer->Secondary Consumer->TertiaryConsumer-> Quarternary Consumer->Top Predator
12. Energy enters the ecosystem food chain in what form?- sun light
13. What do the arrows in question # 11 represent?- what the food is being eaten by
14. What might happen to the food chain if one element were to be eliminated (by disease or habitat loss, for example)?- all the other food that eats that or eats the food that eats that food would die or have to adapt to a new source of food
15. How do wetlands positively affect water quality?-water runoff from higher dry land before the runoff reaches open water. As the runoff water passes through, the wetlands retain excess nutrients and some pollutants, and reduce sediment that would clog waterways and affect fish and amphibian egg development
16. How do wetlands offer flood protection?-Wetlands function as natural sponges that trap and slowly release surface water Trees, root mats, and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain
17. How do wetlands protect shoreline from erosion?-Wetlands at the margins of lakes, rivers, bays, and the ocean protect shorelines and stream banks against erosion. Wetland plants hold the soil in place with their roots, absorb the energy of waves, and break up the flow of stream or river currents.
18. How do wetlands provide habitat for wildlife?-More than one-third of the United States' threatened and endangered species live only in wetlands, and nearly half use wetlands at some point in their lives. Many other animals and plants depend on wetlands for survival.
19. What other benefits do wetlands offer?-people can hunt them
