Flooding chapter/moon Flashcards
the moon is what to the earth?
satellite
how long is the moons revolution?
29.5 days 1 month
phases of the moon in order
new moon, waxing crescent, first quarter, waxing gibbous, full,waning gibbous, third quarter, waning crescent, new
New (also called the Dark Moon)
not visible
waxing crescent
on the right side it is glowing
First Quarter
commonly called a “half moon”, right side is glowing
Waxing Gibbous
right side is glowing; more than the crescent
Full
we can see the entire illuminated portion of the moon
Waning Gibbous
left side is glowing; more than the crescent
Third Quarter
another “half moon”, but the illuminated part is opposite of the First Quarter; left side is glowing
Waning Crescent
left side is glowing
what we see on the moon
reflective surface
why is the red river so susceptible to flooding?
a lot of other rivers go into the red river, topography, climate, gradient
red diver flooding
climate, geology
climate
wet phase of regional climate, the spring thaw, ice dams,
geology
a glacial lake plain, lake agassiz, very young
warm front
a front along which a warm air mass overrides a retreating mass of cooler air
cold front
a front along which a cold are mass thrusts beneath a warmer air mass
what factors influence tempture on earth?
latitude, elavation, proximity to H2o, cloud cover, wind, snow melting reflecting the sun with the white snow
what’s the difference between weather and climate?
weather- condition of the atmoshpere in a particular area
Climate- the average weather experienced by a region
whats the same between weather and climate?
influenced by solar radiation, topography, and water
the atmosphere
thin envelope of air that surrounds the earth . composed of nitrogen, oxygen
weather
condition of the atmoshpere in a particular are
climate
the average weather experienced by a region
stream
any flow of water through a channel
water moves through what?
the hydrologic cycle
streams begin as what?
meltwater from glaciers, runoff from the land surface, or outflow from lakes or springs
the hydrologic cycle
water evaporates from the ocean and rises through the atmosphere, where it condenses to form clouds. the clouds release precipitation that may flow overland in streams, sink underground as groundwater, or be absorbed by plants.
base level
lowest point to which a river can flow
ultimate base level
the ocean
drainage basin
drained by a stream and its tributaries; separated by high ground
divide
separates a drainage basin by high ground
stream gradients
change in elevation of a stream over a given distance
when do stream gradients decrease?
downstream direction
stream channel
channel roughness
