time it takes for water to be recycled
through the water cycle.
Uneven heating of the earth’s surface.
Global (prevailing) winds and local winds.
67) What causes a hurricane?
The formation of a hurricane requires two
key ingredients: heat and moist air. In
the summer and early fall, masses of air
heat up over warm ocean waters and absorb
moisture, creating the conditions that
generate a hurricane. Air flow in a
hurricane spirals around the center or eye
of the storm. The eye of a hurricane is
deceptively tranquil (peaceful), while the
strongest winds and heaviest rains occur in
the region surrounding the eye.
68) What causes a tornado?
Tornadoes form inside thunderstorms when
a cold front or a line of hot, dry air collides
with warm, humid air and winds create a
horizontal spinning effect.
Strong updrafts then pull the warm, moist
air upward and create a giant vertical

chimney of rotating air.
Lost and damage to property, flora & fauna
(plant and animal life, and human life).
A cold front is defined as the transition
zone where a cold air mass is replacing a
warmer air mass. Cold fronts generally
move from northwest to southeast. The air
behind a cold front is noticeably colder and
drier than the air ahead of it. When a cold
front passes through, temperatures can drop
more than 15 degrees within the first hour.
A warm front is defined as the transition
zone where a warm air mass is replacing a
cold air mass. Warm fronts generally move
from southwest to northeast and the air
behind a warm front is warmer and moister
than the ahead of it. When a warm front
passes through, the air becomes noticeably
warmer and more humid than it was before.
Clear skies, nice, fair weather.
Cloudy, stormy skies.
A thunderstorm is a storm with rain, wind,
lightning and thunder, and sometimes even
hail. This type of storm begins to form
when warm, humid air moves upward
rapidly. The sun heats an area on Earth’s
surface, which then warms the air mass
above it.

85) What is igneous rock?
86) What is sedimentary rock?
87) What is metamorphic rock?
Igneous rocks are called fire rocks and are
formed from cooling lava either
underground or above ground.
Underground, they are formed when the
melted rock, called magma, deep within the
earth becomes trapped in small pockets.
As these pockets of magma cool slowly
underground, the magma becomes igneous
rocks. Igneous rocks are also formed when
volcanoes erupt causing the magma to rise
above the earth’s surface. When magma
appears above the earth, it is called lava.
Igneous rocks are formed as the lava cools
above the ground.
For thousands- even millions of years- little
pieces of our earth have been eroded
(broken down) and worn away by wind and
water. These little bits of our earth are
washed downstream where they settle to
the bottom of the rivers, lakes, and oceans.
Layer after layer of eroded earth is
deposited on top of each. These layers are
pressed down more and more through time
until the bottom layers slowly turn into
rock.
Metamorphic rocks are rocks that have
“morphed” (changed) into another kind of
rock. These rocks were once igneous or
sedimentary rocks. How do sedimentary

88) Explain the Rock Cycle.
89) How can you identify rock forming
minerals?
and igneous rocks change? The rocks are
under tons and tons of pressure, which
fosters heat build up, and this causes them
to change. If you examine metamorphic
rock samples closely, you’ll discover how
flattened some of the grains in the rock are.
The Rock Cycle is a group of changes.
Igneous rock can change into sedimentary
rock or into metamorphic rock.
Sedimentary rock can change into
metamorphic rock or into igneous rock.
Metamorphic rock can change into igneous
or sedimentary rock.

rapid changes on our planet, Earth.
93) What causes rock to break into smaller
pieces?
94) What erodes (breaks down)
landforms?
95) What is weathering?
Erosion
96) What is transport?
It is the movement of eroded material by
wind, water, or ice.
It is when the process of erosion stops and
the transported particles fall out of the
transporting medium and settle on a
surface.
97) What is deposition?
Landslides, volcanic eruptions,
earthquakes, etc.
Freezing and thawing and the growth of
plant roots.
