__December. 17__ page 537 - 15) a. composite, b. rift eruption , c. sheild

page 538 - 12) scientists found parts of land and rocks that were the same on both continents . 13) a. Convergent, b. Divergent , c. Transform 14) because continental-continental boundaries are lightweight, so twhen they collide , the both go upwards and form mountains . They dont form at transform boundaries because the plates will just slide side by side . 15) because the mountiains would start in one place , stop at the edge , and then start again in another place. 16) the contenents would stop drifing, earth might lose its magnetic feild , no more earthquakes and volcanoes, anything using geothermal energy would stop working . 17) because whe they erupt , they send out particles in the magma from inside the earth. 18)because the heavier plate will go beneath the lightter plate, allowing the magna to come out . 19) it expells alot of lava , and it could travel down over houses and building and into the ocean. 20) because every earthwuake involves a unique set of forces and geological strucres that could affect the timing, size and location of an earthwuake . 21) a. trench , b.volcanic belt , c.upper mantel , d.oceanic crust , e. upper mantel ?

from dec. 1 page 4521) jet streams occur in the stratosphere 2) a front is a boundary between two air masses (hot and cold) 3) a stationary front is where no air mass is moving 4) when cold air is displaced it is called a cold front page

459 11) the atmosphere does not get hoptter with increasing height because the air in thinner and displaces it. 12) photosynthetic micro-organisms have role in the composition of earths atmosphere because they produce oxygen gas1 3) 75% of atmospheric mass is found in the troposphere because the rest of they layers compress it and make it more dense 14) the atmosphere of venus is 100 times more pressured than earth because the rest of ha layers compress it, and make it denser 15) because the air has less pressure and they also can use the jet streams 16) sea breezes occur because of the different rates that land and water cool 17) the factors that affect the amount od insulation is solar radiation 18) a. i think that it is fall because it is moslty cold air, but still has a bit of warm air. b.i think that the winds would be blowing south because the warm front is going in that direction. c. warm front, because it is right near it. d. warm, because they are on the warm side of the boundary 19) if earths oceans heated up, it would cause a tropical cyclone

Applying your understanding #20 a.) Albedo i smuch greater in a city than in a forest area because the are more objects that can reflect light, like roofing and ashphalt. A forested area has alot of trees absorbing the light to use for food. b.) White rock. c.) Becaues white rock will not absorb as much sunlight as the black concrete or ashphalt. d.) Tar e.) Because black colour will hold on to the heat from the sun and will slowly release. f.) The easier a material is at sonducting heat will conduct heat at a quicker rate, and the the more thermal cconductors the hotter the city will be.g) the role of conductors in a urban heat island is that the more heat there is, the energy will stay in there and heat it up.
