9 Weeks Notes
section.

2. ecoregion – large unit of land or water
containing a geographically distinct
assemblage of species, natural communities,
and environmental conditions

3. Lighthouse Rock, Palo Duro
Canyon, Texas

4. Davis Mountains, West Texas

5. Texas Gulf Coast

6. Piney Woods of Texas

7. Edwards Plateau, Texas

8. weathering – the breakdown of
rock into smaller pieces by natural
processes
 Chemical:
 Abrasion:
grinding and
wearing down of rock
 Oxidation: chemical
surfaces by other rocks
reaction in which an
element combines with or sand particles
oxygen
 Ice wedging: process
 Acid rain: rain that
where water seeps into
absorbs weak acid that cracks in a
is in the air because of
rock, freezes and
pollution
expands over an over
causing the cracks to
get bigger
 Mechanical:

9. erosion – process by which wind
and water move sediment from
one place to another
Agents
of erosion and weathering:
Ice and glaciers
Snow
Wind
Water
Waves
Gravity

10. drought – an extended period
of dry weather resulting in a
severe shortage of water

11. tsunamis – a large wave or series of
waves that is caused by an
earthquake or volcanic eruption

12. volcanoes – an opening in the
earth’s crust in which molten lava,
ash, and gases are ejected

13. hurricanes – a rotating tropical
storm whose winds have reached
a constant speed of 74 mph or
more

14. deposition – the process by which
transported materials are left in
new locations

15. lightning – a massive electrostatic
discharge between the electrically
charged regions within clouds or
between a cloud and the Earth's surface

16. earthquakes – shaking and vibration at
the surface of the earth resulting from
underground movement along a fault
plane or from volcanic activity

17. How does a volcanic eruption
affect the local environment?
 Lava
flow can burn down trees and other
vegetation in its path, along with manmade
structures. If it runs into an ocean, it might
damage or kill a coral reef, as well as cause the
water to boil, killing the life within.

18. How does a volcanic eruption
affect the local environment?
 Ash
and dust is thrown into the atmosphere, which
blocks the sun’s light. This can lower the
temperature of an area for a period of time, as
well as prevent plants from getting the sunlight
they need for photosynthesis. Weather patterns
are altered during this time.

19. How does a volcanic eruption
affect the local environment?
 Lava
flows are destructive, but over time can add
new material to a landscape

20. Explain why our earth
experiences earthquakes .
 Our
earth’s crust is made up of many pieces like
a puzzle covering the surface of the earth. Not
only that, but these puzzle pieces keep slowly
moving around, sliding past one another and
bumping into each other. We call these puzzle
pieces tectonic plates, and the edges of the
plates are called the plate boundaries. The plate
boundaries are made up of many faults, and
most of the earthquakes around the world occur
on these faults as rocks suddenly shift or break
under stress.

21. Tectonic Plates

22. Name and describe a large storm
that develops over an ocean. List
all names for it.
 Hurricanes
can be up to 600 miles across and
have strong winds spiraling inward and upward
at speeds of 74 to 200 mph. Each hurricane
usually lasts for over a week, moving 10-20 miles
per hour over the open ocean. Hurricanes
gather heat and energy through contact with
warm ocean waters. Evaporation from the
seawater increases their power. Hurricanes
rotate in a counter-clockwise direction around
an "eye" in the Northern Hemisphere.

23. Hurricanes

24. Other names for hurricanes
 Tropical
storms occur in several of the
world's oceans, and except for their
names, they are essentially the same type
of storm. In the Atlantic Ocean, Gulf of
Mexico, and the Eastern Pacific Ocean,
they are called hurricanes. In the Western
Pacific Ocean, they are called typhoons.
In the Indian Ocean, the Bay of Bengal,
and Australia, these types of storms are
called cyclones.
