Transcript The Target Standard 2

The Target
Standard 2
There are
different
climates around
the earth.
Did You Know?
• Climate is different
than weather.
Weather conditions
occur every day or
week. It might be
sunny today and rainy
tomorrow and sunny
next week.
Did You Know?
• Climate is how hot or cold
(temperature) and wet or
dry (precipitation) a place
is over a long period of
time.
Did You Know?
• The sun’s rays are
hottest around the
equator. This area
also gets lots of rain.
Climates that are hot
and humid are called
tropical. Lots of big
leaved plants grow
there.
Did You Know?
Places close to the North and South Pole are
always cold with little precipitation, rain or snow.
This cold zone is called tundra. It’s a desert.
The sun’s rays don’t hit directly there.

Did You Know?
• Between the equator and the poles the
climate is usually more temperate or
moderate. The temperatures are
sometimes warm (Florida) and sometimes
cool (Canada). Some places have 4 very
different seasons; hot in summer and
snowy cold in the winter. There is usually
good rain for crops.
Think About It
• Drew’s father wants to study the effects of
cold temperatures on new computer
systems. What location would you
recommend he go to do his research?
The Target
Climates affect
where people
live.
Did You Know
• Few people choose to live in the tundra areas.
Though there are cities in the tundra, the people
who live there get much of their food from other
areas.
Did You Know?
• At the equator, most
places are hot all
year. In the past, few
people lived there.
People invented air
conditioning and now
there are a few big
cities in the tropics.
Did You Know?
• Most large cities are found in the temperate
zone. The conditions for a comfortable living are
highest there. New York City, London, and
Tokyo are all in temperate zones.
Think About It
• Two hundred years ago a
family coming to America
might look for a temperate
climate to live in. What
would their settlement most
likely be like? What
activities would they
probably do to be able to
get along in the new world?
The Target
Landforms affect
where people
live.
Did You Know?
• The Earth is made up
of land and water.
Large land areas are
called continents. On
most physical maps,
the land masses are
colored in greens and
browns.
Did You Know?
• Large bodies of water
on Earth are called
oceans. There are
only five oceans in all
of the Earth. On most
maps they are
colored blue.
Did You Know?
• On a physical map
oceans, rivers, and
lakes will be included.
Also, physical maps
show mountains,
deserts, coastal
areas, and plains.

Did You Know?
• People will use the
landforms, the shape
or form of land, when
they plan where they
will live. Delaware is
a coastal plain so
people choose to live
here to be close to
farm and be close to
the beach.
Think About It
• A family is moving from Alaska to Texas. What
will change for this family when they move?
What can they do to prepare for the move?
Think about climate, precipitation, and
landforms.
The Target
Landforms are
formed by
energy in the
earth.
Did You Know?
• Mountains can be
formed when
pressure inside the
Earth becomes so
great that a volcano
erupts or an
earthquake occurs.
Did You Know?
• Rivers are
formed when
water from rain
and melting ice
and snow flow
down mountains.
The water is able
to dig out a path
and form
streams and
rivers.
Did You Know?
• Soil and rocks get carried
down streams in the
mountains. The strong
rivers carry the soil and
rocks. The soil and rocks
get dropped when the
river runs into an ocean
or large body of water.
This helps smooth out the
earth’s surface.
Think About It
• People who settled
long ago were looking
for sources of fresh
water. How would
knowing about
landforms help people
find good places to
settle?
The Target
The earth
passes through
periods of day
and night.
Did You Know?
• The earth is constantly spinning in place.
Did You Know?
• Every 24 hours the
earth completes one
full spin. When the
sun shines on
Delaware, we know it
will take another 24
hours for the sun to
shine the same way!
Did You Know?
• The sun is shining
even on cloudy days
when we are not able
to see it.
Think About It
• Sometimes it snows in Delaware. What is
necessary for the snow to melt when the
temperature remains very cold?
