Landforms
Weathering

Chemical – includes the effect of
weathering on molecules and atoms oxidation, hydrolysis, and
acidification

Mechanical - Mechanical weathering is the
process of breaking big rocks into little
ones
Slow Weathering
Erosion
Drought
Melting Ice Caps
Fast Weathering
Earthquakes
Tornado
Volcanoes
Flood
Fire
Erosion

Wind erosion – wearing away of earth’s
surface caused by wind

Water erosion – wearing away earth’s
surface by water

Weather and Climate
Weather - The condition of the
atmosphere at a given time and place,
 Weather is measured by temperature,
moisture, wind velocity, and barometric
pressure.

Things used to measure weather
Thermometer –
Used to
measure
temperature
Anemometer –
used to
measure wind
speeds
Barometer –
Used to
measure
barometric
pressure
Climate

Climate is the average weather usually
taken over a 30-year time period for a
particular region and time period
Green – Rain
White – Snow
Pink – Rain/Ice/Snow mix
Weather Map
L – signifies a
low pressure
area
 H – signifies a
high pressure
area

Warm Front
Cold Front
Sources of Water

Ground water – water found beneath the
earth’s surface.
Surface water – water found on the
earth’s surface, this water is replenished
by precipitation, this is a natural source of
water
 Lakes hold most of Earth’s fresh water

Unnatural Sources of Water
Unnatural sources of water are sources man
has created
 Bottled water
 Tap water (water that comes out of the
faucet)
 Distilled (bottled water)

Atmosphere – water that comes from the
atmosphere, this includes rain, sleet, hail,
and snow
