Why did Westerner’s hypothesis of continental drift fail and what was the evidence needed to support his predictions- why was it literally an idea before its time? Because no One could explain how massive continents Of solid rock could drift across earths surface.
It was ahead of its time because there was o way of finding the evidence to support it until technology was invented in the form of a fathomed to map the deepest depths. Of the ocean floor. 2. Summarize plate tectonics. It explains the theory of how the changing surfaces of the earth are formed. 3. What are convection currents and what is their role in plate tectonics? Convection currents are the rise and lowering of heat in tee earths mantle like a boiling pot of water. The heat is denser at the bottom of the pan it rises the falls to the bottom and repasts it self. This rising and dropping is the effect that why the plates move. . Compare the three types of plate boundaries: divergent, convergent, and transform plate boundaries. Explain the movement and processes associated With each boundary, the landforms that develop as a result of these processes, and the locations where these boundaries/landforms are found on Earth. Movement and processes associated landforms that develop as a result Divergent Plates are moving away from each other Mountains, lava fills the area when the plates move away from WAC other and cools causing Convergent Plates come together in slow misconstructions. One plate falls below the other.
Ocean mountains, mountain ranges ND coastal mountain Transform They just slide past WAC other Connect two ridges to make one continuous ridge locations where on Earth mountains Sea floor and middle of a continent Ocean, ocean and continent, continent and continent fault 5. Explain how convection cells cause the following types of air movement in the atmosphere: local winds and Hadley cells. LOCAL WINDS- as the warm air rises it creates wind the convection cell is the lower pressure warm air rising to meet the cooler higher pressure air and lowering and repeating this process causes wind.
Hadley cells create prevailing winds or trade winds fro -30 degrees from the earthquake. Use Chapters 23 and 24 in Conceptual Integrated Science to address the following in your notes: 1 . What is weathering? Is the disintegration or decomposition of rock at or near the earths surface. Such agents as water wind ice and chemicals weather the rocks. 2. Describe mechanical and chemical weathering. MECHANICAL WEATHER-STRIPPING CAUSED BY WATER BREAKS ROCK DOWN INTO SMALLER PIECES ice wedging is a process of mechanical weathering.
CHEMICAL WHEAT HIRING is the main producer of sediment. The compounds in rock decompose into substances that are more stable in the earths environment water is again the main culprit when it rains the water acts with carbon dioxide in the soil to cause the rain to be acidic. It chemically reacts to minerals in the rock. 3. Explain the process of erosion. Is the process were weathered particles of the rock are moved by streams glaciers, wind and other mobile agents 4.
Describe the action of the following erosion agents: gravity, surface water, groundwater, wind, and glaciers, and think about how each can change the Earth’s surface Website Visit Visit the following website and take notes on specified types of mechanical ND chemical weathering of rocks, as outlined below.

Types of mechanical weathering: a. frFrostedging when water seeps into a crack in the rorocknd freezes it expands and breaks the rock apart. b.BExfoliation when a rock breaks off the earth’s surface and slides down it exfoliates the other rocks it sliding down . thThermalxpansion heating and cooling of the rock happens in the desert regions. d.DcrCrystalrowth when salt gets in the pores of the rock and then evaporates the crcrystalxpansion breaks apart the rock e. trTreeoots like ice wedging the roots gegettinghe rock and when they grow they break the rock warm moist regions. . Abrasion it is the rocks breaking down by direct action of other rocks like when rocks fall from a mountain. 2. Types of chemical weathering: a.

Describe the layers of Earth’s atmosphere: a. Troposphere the lowest layer of the atmosphere. The thinnest layer.
Most of the earths gas molecules are in this layer because of gravity. Contains 90% of the atmospheres mass. And almost all of earths water vapor and clouds. It is the densest atmosphere layer. b.BStratosphere it is above the troposphere. Ozone molecules form here and absorb ultraviolet radiation from the sun c. Mesosphere the next layer above the stratosphere. The gases that make up this layer absorb little radiation temperatures start at O degrees to -90 degrees. d.DThTroposphereere temperature increase with altitude. There is little air in this layer but what air there is absorb solar radiation e.
Ionosphere is a ion rich region within the thtropospherend upper mesosphere. f.FExosphere is the spars outermost layer of the atmosphere that gradually thins until it yields to radiation belts and magnetic fields of space. 2. Make note of the components of Earth’s atmosphere: Nitrogen, Oxygen, Argon, Neon, Helium, Methane, Hydrogen, Water Vapor, Carbon Dioxide, Ozone… 3. Which gases Of Earth’s atmosphere are most abundant? (ieiiitrogen, Oxygen) Which gases are found in trace amounts? (ieiiater Vapor, Carbon Dioxide… ) 4.
Explain the CoAcropolisffect is the earth rotation having affect on free moving things ikekeir wind airplanes the plain in going in a straight line but to the rotation of the earth it will not get to its destination 5. How does humidity differ from relative humidity? The amount of water vapor in the air is HUMIDITY. ReRelativeumidity is the ratio of the amount of ateaterapor currently in the air compared with the largest amount of water vapor that is popossiblehe air to hold at that temperature. 6. Describe the different types of air masses. Arctic, maritime ararcticool, moist unstable.
Greenland, continental artic, cool dry stable. North atAtlanticacific ocean maritime polar, cool moist unstable. Alaska Canada, continental polar, cool dry stable. CaCaribbeanea Gulf of meMexicoaMaritimeropical warm moist usually unstable. Mexico southwestern US, CoContinentalropical, hot srsirtable aloft unstable surface. 7. Explain the changes in weather that accompany a cold front. How do the changes differ when a warm front moves into an area? A cold front you observe high cirrus clouds, a shift in wind direction, a drop in temperature, and a drop in air pressure. heHeold front might produce thunderstorms with heavy showers and gusty winds. A warm front approaches more gradually than a cold front, the ararrivalf a warm front is also with cirrus clouds. Ahead of a warm front the cirrus clouds thicken into alultimatum’snd alto stratus clcloudshat turn the sky a overcast gray. Closer to the front light or moderate rain or snow can happen,. 8. Describe the changes in weather ssassociatedith a low-pressure center (cyclone) and a high-pressure center (anticyclone). 9.
