Sun & Seasons Pt. 2
This is Earth's yearly trip around the sun, taking about 365 days.
What is revolution?
This large geographic feature helps moderate coastal temperatures, keeping them more constant than inland areas.
What is a large body of water (an ocean or lake)?
The Dead Sea and Utah's Great Salt Lake are unusual because they are lakes containing this.
What is salt water?
Burning fossil fuels releases gases that cause this type of acidic precipitation.
What is acid rain?
This internal process happens when one tectonic plate dives beneath another.
What is subduction?
This is a day when daytime and nighttime are nearly equal length everywhere on Earth.
What is an equinox?
This term describes air movement in a region that blows in a fairly constant directional pattern.
What is a prevailing wind?
This is the average daily temperature of a tropical wet climate.
A) 32°F (0°C) B) 50°F (10°C) C) 80°F (27°C) D) 100°F (38°C)
What is about 80°F (27°C)? (C)
This hazy air pollution forms when exhaust is heated by solar radiation in the atmosphere.
What is smog?
This external process wears away Earth's surface through wind, glaciers, and moving water.
What is erosion?
If Earth's axis were NOT tilted, this is what would happen to the seasons.
What is: there would be no seasons (temperatures would stay fairly constant all year)?
These prevailing winds blow diagonally toward the east in the midlatitudes.A) Trade winds B) Westerlies C) Doldrums D) Monsoons
What are the westerlies? (B)
This expensive process removes salt from ocean water to create freshwater.
What is desalination?
This gradual rise in Earth's average temperature is linked to added greenhouse gases from human activity.
What is global warming?
These large piles of rocks and debris are left behind when glaciers melt and move back.
What are moraines?
This term describes sunlight that hits Earth's surface more directly, delivering more heat and energy.
What is direct sunlight?
This mountain city in Ecuador stays cool despite sitting near the Equator, because of its elevation
A) Bogotá B) Lima C) Quito D) Caracas
What is Quito? (C)
This term describes an underground, porous rock layer often soaked by very slow flows of water.
What is an aquifer?
This is one major consequence of global warming that affects coastlines worldwide.
What is rising sea/ocean levels?
This South American mountain range formed as the Nazca Plate slides under the South American Plate.
What are the Andes?
Explain, in your own words, why the Northern and Southern Hemispheres always have opposite seasons.
What is: Earth's tilt makes one hemisphere lean toward the sun (summer, more direct sunlight) while the other leans away (winter, less direct sunlight) at the same time?
Explain, step by step, how a rain shadow forms on the leeward side of a mountain.
What is: moist wind is forced up the windward side, cools, and drops its rain there — the air that reaches the leeward side has little moisture left, so that side stays dry?
Name all five factors that influence soil formation.
What are climate, topography, geology, biology, and time?
Name at least two reasons desalination is not a perfect solution to freshwater shortages.
What is: it is very expensive, and it can harm marine life and coastal water quality
Name the two basic kinds of weathering and give one example of each.
What are physical weathering (e.g., water freezing and splitting rock) and chemical weathering (e.g., rainwater dissolving limestone)?
