|
_____ is the ultimate source of energy for weather and climate and the disasters they cause
|
the sun
|
|
|
gravity is an agent of the distribution of _____
|
energy
|
|
|
_____ involves short-term processes and is what you actually get; _____ involves long-term processes and is what you expect
|
weather; climate
|
|
|
the sun heats the earth _____
|
unevenly
|
|
|
The equatorial regions of the Earth receive about _____ (less/more) solar energy than polar regions
|
2.4; more
|
|
|
Earth's spin and gravity set up _____ in the ocean and the atmosphere to even out heat distribution (since equatorial regions receive more solar energy)
|
circulation patterns
|
|
|
circulation patterns do what?
|
even out the heat distribution
|
|
|
circulation patterns determine _____ and ______
|
weather; climate
|
|
|
Gravity pulls/attracts the ____, _____ dense air as well as water vapor and creates circulation currents in the atmosphere?
|
colder; more
|
|
|
hot air is _____ dense than cold air
|
less
|
|
|
What natural feature has protected New Orleans for decades? How? Why are they no longer protecting the coastline?
|
wetlands; they were used to protect the coast from storm surges by soaking up excess water like a sponge; when the levees were built they prevented the Mississippi River from flooding, causing the wetlands to stop replenishing and disappear; this causes storm surges to continue to rise
|
|
|
a generalized term for movement of materials downslope
|
mass wasting
|
|
|
processes by which rock materials are decomposed by the alteration of parent material
|
chemical weathering
|
|
|
salt dissolving b breaking into sodium and chlorine ions is an example of _____ weathering
|
chemical
|
|
|
carbonic acid breaking down limestone into calcium bicarbonate and carries it away is an example of _____ weathering
|
chemical
|
|
|
involves ALTERING the parent material
|
chemical weathering
|
|
|
when physical forces break materials into smaller pieces
|
mechanical/physical weathering
|
|
|
frost action, pressure release. thermal expansion and contraction, salt crystal growth, and the activities of organisms are all examples of _____
|
mechanical/physical weathering
|
|
|
involves forces breaking things into smaller pieces
|
mechanical/physical weathering
|
|
|
the products of mechanical weathering are chemically _____ as their parent materials
|
the same
|
|
|
when we fracture and break things up, erosion goes _____; why?
|
faster; there is more surface area, which thereby increases the chance for weathering
|
