destructive & constructive forces of nature
DESCRIPTION
My son had to do another powerpoint in science class in 5th grade on Destructive & Constructive forces of nature. I helped him with this one and also shared it with my 5th grade students at the time. Students using technology.TRANSCRIPT
Destructive & Constructive Forces of
NatureBy: J.C.- Ms. Hernandez (5th
grade)
Students erupting a
volcano with baking
soda and vinegar!
Volcano: a mountain formed by lava and
ash.
Lava is magma that reaches the Earth’s
surface. Volcanoes push up new rich soil
to the surface.
They form on the plates in the Pacific
Ocean
Tornadoes: a spiral shaped wind storm
Tornadoes are common in the middle
of the U.S.
Tornadoes are like spinning tops.
Spiral shaped cones
Destroy buildings/homes
Hurricanes occur in the oceans. The
eye is in the center of a hurricane.
Hurricanes bring about tropical storms.
Strong winds Heavy rains causing floods.
Earthquakes: shaking of the ground.
Japan recently had 3
earthquakes.
Fault: crack in the Earth’s crust.
EarthquakesCalifornia gets a
lot of earthquakes.
Fault: a crack in the Earth’s crust.
Seismograph (instrument) Richter scale
measures the magnitude or strength of an
earthquake
Tsunami: a HUGE wave
Thunderstorms:thunder, lightning & rain
Lightning is Electricity!Double Trouble! A man struck by
lightning!
Wildfires: forest fires out of control.
Forest fires: killing our trees=
our oxygen.
Firefighters risk their lives.
Wild Forest FiresSmokey the Bear helps to educate
about fires.
Humans / campfires
In danger of burning this beautiful home in
the mt.
Trying to prevent Flooding.
Building a barricade.
Filling in sand bags.
Floods:destroy roads/ homes.
Cars stuck.Getting out and
staying in a shelter.
Mass Movement- Mudslides can
bury homes, cars, and people.
A mudslide is a downhill
movement of rock & soil
because of gravity.
BOULDER: a huge rock
Acid Rain: polluted water with chemicals that destroy
statues.
Water erosion: rocks over time become round and
smooth.
Weathering & ErosionWaves crashing against rocks.
A big chuck departed.
Weathering & ErosionShape new landforms.
Beautiful art landforms.
Weathering: water freezes (ice) expands and breaks
down rocks.
Water ErosionWater eroded the soil leaving the roots exposed.
The beach house- waves eroded the
soil.
Deposition: moving sediment into a NEW
LOCATION. Sediment moving down the river and pouring into the delta- mouth of the river.
Changes to the Earth’s surface create new
landforms.
