Directions: Fill in the chart below with the missing information regarding the opposite seasons in different hemispheres Northern Hemisphere Summer Spring winter Fall Southern Hemisphere winter Fall Summer spring

3 Directions: Fill in the chart below by indicating the amount of daylight hours each season would experience in New York State. Season Indicate the amount of daylight hours compared to the amount of night time hours (choose one) Spring More Less Equal Summer More Less Equal Fall More Less Equal Winter More Less Equal Moons diagram Directions: Label and draw the moon phase at each point of the below. Waxing gibbous 1 st quarter Waxing crescent Full moon Lunar New Solar Waning gibbous Waning crescent 3 rd quarter There are 2 positions on the moon diagram above that eclipses can be viewed. 1) Next to the moon phase that a solar eclipse might occur at - put S. 2) Next to the moon phase that a lunar eclipse might occur at put L.

4 H-R Diagram What star in the least luminous on the chart? Proxima Centauri What star in the most luminous on the chart? Deneb Does Spica or Deneb have the higher temperature? Spica Describe the relationship between surface temperature and luminosity of main sequence stars on the chart above regarding the characteristics of stars. It is a direct relationship as temperature increases luminosity increases. What is the process that fuels stars? Nuclear fusion

5 Electromagnetic Spectrum Which color visible light has the longest wavelength? RED Do x-rays or microwaves have a shorter wavelength? X rays Which energy of the chart above has the most energy? Gamma Rays List out the order of the electromagnetic spectrum from least to greatest energy Radio,microwaves,infrared,visible light,ultraviolet, xrays, gamma rays Earth Science A B C D What happens to the age of the rock from point A to point B? it decreases What happens to the age of the rock from point C to point D? It increases What happens to the age of the rock from points A to B to C to D? it decreases then b to c is new ocean crust then it increases.

6 What is sea floor spreading? The process by which new ocean crust is produced at the mid ocean ridge and old ocean crust is recycled at subduction zones. What is subduction? The process by which ocean crust is recycled at subduction zones (convergent boundaries) where the high density ocean crust is forced under the continental crust and back into the mantle. What does the Theory of Continental Drift State? The continents were once joined in a single landmass (Pangea) that broke apart into tectonic plates that migrated away from each other. Help fill in the chart of evidence that the Wegner gave to support his theory. Evidence Continents fits together like puzzle pieces. Climate change glacial scratches found on rocks in India Fossils of plants found in Antarctica which has been covered by ice for human history Mesosaurus was found on the continents of South America and Aftrica. Mountain Ranges in North America lined up with those in Europe. Reason Why it Supports the Theory Because they are pieces of the mega continent Pangea. India must have been in an area once that was colder, it must have moved to its present day location from that colder area. Antarctica must have been in a warmer location at one point and moved to its present day location. This fresh water animal could not have swam across the ocean, therefore the continents must have been together. These folded mountains must have been created at the same time as a result of the same forces.

7 Rock layers lined up across continents. These layers were laid down at the same time. Scientific Method Define the steps of the scientific method Step Problem Hypothesis Materials Procedure Data Analysis & Conclusion Definition An observation of the natural world that the investigator beleves is associated with a cause. Phrased usually with What is the effect of or what factors cause A formalized proposal of cause and effect. The format is If the independent variable changes then the dependent variable changes, The raw materials, population, equipment and supplies needed to conduct the experiment. The step by step process to complete the experiment. The observations recorded in response to a change in the independent variable A discussion as to whether the data supports or doesn t support the original hypothesis.
