Neptune
The closer a planet is to the sun the
hotter it is. The farther away a planet is
from the sun the colder it is.

No liquid water
Many craters because it
lacks atmosphere

Weather, describes the daily conditions in the atmosphere of a local
area. It includes conditions such as cloud cover, wind, humidity,
precipitation and temperature, which is how hot or cold the air is.
Sphere of burning gases
Made of hot gases
Rotates on an axis
Source of heat and light for our solar
system
Medium sized star
A million times bigger than the Earth
No real surface
Center of our solar system

Weather is constantly changing. Scientists who predict, or forecast,
the weather can’t usually make forecasts beyond 10 days. Even
weather reports cannot guarantee that the forecasts will be
accurate.
Weather is over a short period of time and changes often.
Climate is the type of weather in an area averaged over a long period of
time, such as 30 years or more.
Climate is consistent and doesn’t change.
The climate of an area describes its average temperatures,
precipitation, humidity, wind, cloud cover, and other weather
conditions over long periods of time.
Climate is what the weather usually is in a certain area.
Tides

Tides are the daily rise and fall of Earth’s waters on its coastlines.
As the tide comes in, the level of water on the beach rises, and as the tide goes out, the level of water on the beach
goes down.
Tides occur in all bodies of water, but they are most noticeable in the ocean and large lakes.
The Moon’s gravity affects the water on Earth’s surface.
Since the Moon is close to the Earth, it has a strong gravitational pull on it (closer objects have stronger gravitational
pull) which CAUSES THE TIDES
Low tide
There are 2 high tides and 2 low tides every 24 hours. There is approximately 6 hours between the high tide and low
tide.
Moon Phases
 We see the moon from Earth as it orbits us. The way the moon appears changes depending on where the moon is in
its orbit.

In the lunar cycle, the light starts on the right and gradually grows
larger. The appearance of light moves from right to left.
