GLAB Unit 1 Part 5 – foundational concepts, review material, and
practice questions
The amount of radiation available at the top of the atmosphere is a function of... - correct
answer ✔✔latitude and the time of year
and this is because - correct answer ✔✔locations move between more concentrated and more
dispersed sunlight.
Does all of the radiation at the top of the atmosphere reach Earth's surface? - correct answer
✔✔No, Some radiation is absorbed and scattered back to space by air molecules, atmospheric
dust, and clouds.
Solar Radiation - correct answer ✔✔The amount of radiation available at the top of the
atmosphere is a function of latitude and the time of year, because locations move between
more concentrated and more dispersed sunlight. However, not all of the radiation that is
available at the top of the atmosphere reaches Earth's surface!2. Some radiation is absorbed
and scattered back to space by air molecules, atmospheric dust, and clouds.
The closer contour lines are to each other... - correct answer ✔✔The steeper the slope
Hachured lines indicate... - correct answer ✔✔a depression or a decrease in elevation
READING TOPOGRAPHIC MAPS - correct answer ✔✔The closer the contour lines are to each
other, the steeper the slope
Hachured lines indicate a depression or a decrease in elevation
Pay attention to the legend, scale, and units!
