Although some skeptics points to arctic places such as the high latitudes of greenland, where temperatures seem to have fallen, a recent scientific report concludes that in recent decades average temperatures have increased faster in the arctic than elsewhere. scientists have long suspected that several factors lead to greater temperature swings at earths polar regions than elsewhere. first, most of the arctic is covered in snow and ice, which are highly reflective; if snow and ice melt, the exposed soil, which absorbs heat, serves to accelerate warming. second, the polar atmosphere is thin, so little energy is required to warm it. third, less solar energy is lost in evaporation at the frigid poles than in the tropics. consider each of the choices separately and select all that apply. the passage mentions which of the following as factors that might lead to large temperature swings in earths polar regions? athe amount of energy lost due to evaporation at the polesbsoil exposure due to melting snowcthe relatively thin atmosphere at the poles

Directions you probably already know that people have different ways to organize their ideas. some people make lists or outlines, some draw pictures, while others may combine these two methods. experiment with different note-taking techniques to find the one which works best for you. one common note-taking technique is webbing. webbing uses the sizes of circles to indicate the importance of items. lines are used to indicate the relationships between items. the example below is based on the information presented in a previous lesson. notice that the circle for "geography is" appears at the center of the web. it has larger than the circles that surround it. the "geography " circle is surrounded by smaller circles of earth's atmosphere, earth's climate, earth's surface. notice the lines that connect these items to the concept of geography. notice that the circles surrounding atmosphere are smaller. also observe that the lines that connect the items and indicate the relationships between the items. webbing will you capture the most important points in your lessons. beginning with lesson two, geographic tools: globes and maps, use webbing to take notes on the important information in this unit. hint: it will be easier to complete this project if you take your notes after completing each lesson.
