The Sun
The location of the sun in our solar system
What is the center?
The two factors that can change the gravitational pull between two objects.
What are mass and distance?
This is the number of seasons we experience in a year.
What are 4?
This is the vertical invisible line of which the Earth rotates around, and it's tilted.
What is the axis?
This is the name of the line of division for the light side and dark side of the moon.
What is the terminator?
The cooler dark blotches on the surface of the sun
What are sunspots?
Gravity is this kind of force (there are two types of force)
What is a pulling force?
These are the names of the four seasons
What are winter, spring, summer, fall/autumn?
This is the amount of days it takes Earth to revolve around the sun one time
What is 365 (1/4)?
The phase of the moon where the right half of the moon is illuminated.
What is the first quarter?
The two resources we need from the sun to survive
What are light and heat?
Gravity is a constant so every object falls at this speed on Earth.
What is 9.8 m/s/s?
This angle of Earth causes different seasons.
What is a tilt (23.5 degrees)?
If a rotation of Earth gives us days and nights, what gives us years and seasons?
What is a revolution?
This phenomenon is where the moon is in between Earth and the sun, blocking the sunlight.
What is a solar eclipse?
This layer of the sun produces the light that we see
What is the photosphere?
Objects falling on the moon hit the ground at the same time, while on earth this factor makes objects hit the ground at different times.
What is air resistance?
This invisible line divides the Earth into a northern and southern hemisphere.
What is the equator?
This term reflects the turning of an object around a single point or axis.
What is rotation?
We use a calendar to measure duration of time. These are the measurement of a full moon phase.
What are months or 27-29 days?
The reason behind the sun being in the location it is
What is having the most mass hence the most gravitational pull?
When I travel to the moon one measurement of my body will change and one will stay the same. Name the measurement that will change.
What is weight?
These two seasons have indirect, less concentrated sunlight because of a sideways tilt of Earth to the sun
What are spring and fall?
These are two factors to change an object's orbit
What are mass and distance?
This is the reason why we don't see a lunar eclipse every month.
What is a tilted moon orbit?
