Solar System
This is the term used to describe the sun, all planets, their moons, asteroids, and meteoroids.
Got it
Spring tides
These tides occur during the full moon and new moon lunar phases. There is the greatest amount of difference between high and low tides at this time.
Got it
Neap tides
During the first quarter and third quarter phases of the moon, the moon and sun are pulling in opposite directions. This causes tides to be exceptionally weak, these are called neap tides.
Got it
Name the force that causes oceans to rise and fall.
This is called the tidal force. Larger tides in the ocean are caused by the moon's gravitational pull on the earth, while other tides can be caused by the sun too.
Got it
Name the phase of the moon seen here.
This is the waning crescent moon. This is the final phase of the moon before the sky goes dark and the new moon occurs, starting the four week cycle again.
Got it
Name the phase of the moon seen here.
This is the third quarter moon, but it is also occasionally called the last quarter moon. This occurs three weeks after the new moon.
Got it
Name the phase of the moon seen here.
This is the waning gibbous moon. 'Waning' means decreasing, so this is the phase of the moon after it has been full and is now decreasing in visibility.
Got it
Name the phase of the moon seen here.
This is the full moon. During this phase, the moon is perfectly opposite the sun. This illuminates the full side of the moon we can see in our sky. This occurs two weeks after the new moon.
Got it
Name the phase of the moon seen here.
This is the waxing gibbous moon.
Got it
Name the phase of the moon seen here.
This is the first quarter moon. In this phase, we are able to see half of the moon. This occurs roughly 7 days after the new moon.
Got it
Name the phase of the moon seen here.
This is the waxing crescent moon. Waxing means increasing, so this moon is on the way towards full visibility.
Got it
New moon
This is the phase of the moon during which it appears there is no moon at all in the sky. This is due to the sun lighting the half of the moon that we do not see.
Got it
Identify the eight phases of the moon.
The phases of the moon are new moon, waxing crescent moon, first quarter moon, waxing gibbous moon, full moon, waning gibbous moon, third quarter moon, and waning crescent moon.
Got it
Tropic of Capricorn
The line of latitude at 23 degrees south of the equator. The area between this and the Tropic of Cancer is consistently warm all year.
Got it
Tropic of Cancer
The line of latitude at 23 degrees north of the equator. The area between this and the Tropic of Capricorn is consistently warm all year.
Got it
Antarctic Circle
This is the line of latitude at 66 degrees south. Due to the Earth's axis tilt, this area has constant daylight in the winter and darkness in the summer.
Got it
Arctic Circle
This is the line of latitude at 66 degrees north. Due to the Earth's axis tilt, this area has constant daylight in the summer and darkness in the winter.
Got it
Climate
This is the term used to describe the general weather and temperature conditions of a particular area. The Earth's rotation on its axis and its revolution around the Sun impact this.
Got it
Axis tilt
This is the term used to describe the angle of the Earth as it rotates on its axis, or the invisible line down the center of the Earth. This impacts the varying seasons and hours of daylight.
Got it
Orbital revolution
This is a term used to describe a planet's rotation around another object. For example, the Earth travels in orbital revolution around the sun.

Flashcard Content Overview

When you look up at the night sky, you may feel quite overwhelmed by the vastness of space. There are so many complexities to be found in that sky, from the moon, planets, and even the occasional comet! These flashcards will review topics related to the planet that we live on, Earth, and other important parts of our solar system. You will also learn about space history and notable astronauts that made giant leaps in our space discovery.

Name the eight planets of our solar system in order from closest to the sun to furthest from the sun.

Sun
In our solar system, the sun is the central star and it is the biggest object in our solar system. The eight planets of our solar system orbit the sun.
Name the four terrestrial planets.
Mercury, Venus, Mars, and Earth. These plants have solid surfaces.
Name the four Jovian planets.
Jupiter, Saturn, Uranus, and Neptune. These planets are large balls of gas lacking a solid surface.
Moon
A moon is a naturally occurring satellite of a planet. Each planet in our solar system varies from having zero to over 50 moons.
Name the main layers of the sun's atmosphere.
The main layers of the sun's atmospheres are the corona, chromosphere, and photosphere.
Name the temperature of the sun's surface.
5800 K or about 10,000 degrees Fahrenheit
Name the two most abundant elements that make up the sun.
The sun is primarily made up of hydrogen, while helium is the second largest element found in the sun.
Name the five planets that we are able to see naturally; the planets that are called the five naked-eye planets.
Mercury, Venus, Mars, Jupiter, and Saturn
Ecliptic
A large spherical path that the sun follows and completes in a year. Jupiter, Saturn, Uranus, Neptune, and Mars move eastward close to the ecliptic.
Regular satellites
These are moons that are large and orbit close to their parent planet. Their orbit is typically in a circular motion and their rotation follows the same direction as the parent planet.
Irregular satellites
These moons orbit far from their parent planet and are often smaller than typical satellites.
Collision fragments
These smaller satellites are broken pieces of a past large satellite. They are formed when these satellites crashed into a meteoroid. These are most commonly found orbiting the Jovian planets.
Shepherd satellites
These are satellites that orbit very close to their parent planet. Through their gravitational pull, they can pull in particles like dust and rocks to the planet's ring.
Comet
A comet is a glowing ball of ice that develops a long tail as it gets close to the sun and orbits through space. Some comets are predictable, like Halley's Comet, while others are newly found.
Asteroid
An asteroid is an object that orbits the sun. It is small, when compared to the sun, but can range in size from a few feet long to over 950 kilometers wide.
Meteorite
A meteorite is an object that came from space and entered the earth's atmosphere. Most meteorites burn up after entering the atmosphere, but about 500 per year hit the surface of the earth.
NASA
The National Aeronautics and Space Administration (NASA) is a division of the U.S. Government that drives space exploration and research.
Name the person who first walked on the moon and the year that it occurred.
Neil Armstrong, part of the Apollo 11 mission, stepped foot on the moon in 1969 and made history as the first person to ever do so.
Space race
A historic competition between the USA and the USSR to become the most advanced country in human spaceflight.
Name the first human to ever orbit earth.
In 1961 the USSR space shuttle, the Sputnik 1, orbited the earth with Yuri Gagarin onboard.
