Earth is divided by an imaginary line called the what?
equator
Name the four seasons we experience in Kentucky.
Fall, Spring, Winter and Summer
The Earth is divided into two parts. Name the parts.
Southern Hemisphere and Northern Hemisphere
Which hemisphere is the United States located.
Northern Hemisphere
Name a country that is located in the Southern Hemisphere.
Australia
How many hours are in a day?
24 hours are in one day
How many days are in one year?
365 days are in one year; 366 in one leap year
How do scientist determine how many hours are in one day?
The amount of time it takes a planet to rotate one time on
its axis.
How do scientist determine how many days are in one year?
The amount of time it takes a planet to revolve around the
sun.
The path that a planet takes around the sun is called what?
Orbit
What is the shape of Earth’s orbit?
Elliptical or oval shaped
Our seasons are caused by two major factors. What are they?
Earth’s tilt and the direct or indirect rays of the sun
Earth is tilted on its axis at what degree?
23 1/3 degrees
Explain what is happening between the sun and the Earth when the
Northern Hemisphere is experiencing summer?
The Northern Hemisphere is tilted toward the sun and is
receiving direct rays.
When the Northern Hemisphere is experiencing summer, what
season is it in the Southern Hemisphere?
winter
16.
Draw a picture of the Earth and the sun if it is summer time in the
Southern Hemisphere.

If an object has a large amount of mass, what will happen to its
weight and gravity?
It will increase.
Why is it always warmer at the equator?
The equator always receives direct sun rays no matter which
direction the Earth is tilted.
Definitions:
Mass-the amount of “stuff” that is inside something
Weight-how we measure the gravitational pull on an object
Matter-any solid, liquid or gas that occupies space and has mass
Gravity-the force that pulls down on an object
Rotation-the amount of time it takes a planet to spin one time
on its axis
Revolution-the amount of time it takes a planet to revolve one
time around the sun
Axis-the imaginary pole that runs through the North and South
pole
Earth’s distance from the sun has nothing to do with changing
seasons. The 23 1/3 degree tilt of Earth on its axis and the kind
of rays received in a hemisphere determines the seasons. For
example, the Earth is actually 3 million miles farther away from
the sun in the summer time than in the winter time. In space 3
million miles is no big deal! Even though the Earth is farther away
from the sun, it will be warmer because the Northern Hemisphere
is tilted toward the sun and is receiving direct sun rays.
