How old is our solar system?
What is ancient?
Closest to the sun and is a small, heavily cratered planet, looks like our moon, and is the smallest planet with a thin atmosphere.
What is Mercury?
The seventh planet from the sun. It is a gas giant and is unique in that it spins on its side. It has a large atmosphere and is a cold planet that is four times the size of Earth.
What is Uranus?
These cause the sun's rays to hit Earth's surface at different angles. They cause direct rays to be more intense resulting in higher temperatures at those locations.
What is Earth's axial tilt?
Average sized yellow star, about 110 times the diameter of Earth and is approximately 4.6 billion years old.
What is the sun?
What early astronomers believed about what is at the center of the universe and what we know today?
What is Earth was at the center but bow we know our sun is at the center of our solar system and the planets revolve around the sun?
The second planet from the sun, similar to earth in size and mass, has a permanent blanket of clouds that traps thermal energy and causes high surface temperatures.
What is Venus?
A very cold planet. It is eight from the sun. It appears blue because of its atmosphere and is roughly four times the size of Earth.
What is Neptune?
These are caused by its position relative to the Earth and the sun. They are caused by the reflection of sunlight off the moon's surface. They are responsible for tidal ranges.
What are phases of the moon?
It's large amounts of life-supporting water and an oxygen-rich atmosphere. Earth's protective atmosphere blocks our most of the sun's damaging rays.
What makes up the solar system? Name them.
What are planets. The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
The third planet from the sun. Its atmosphere, liquid water, and distance from the sun make it ideal for life.
What is Earth?
Is not longer a planet due to its small size and irregular orbit.
What is Pluto?
The phases of the moon.
What are new, first quarter, full, last (third) quarter?
The important features of the ocean floor?
What are the Continental Shelf, Continental Slope, Continental Rise, Abyssal Plain, and ocean trenches?
Terrestrial planets
What are Mercury, Venus, Earth, and Mars
The fifth planet from the sun, the largest in the solar system (elven times larger than earth) and is considered a gas giant. It has no solid surface, its colored cloud patterns are caused by enormous storms in its atmosphere.
What is Jupiter?
The fourth planet from the sun, sometimes called the red planet, its atmosphere is thin, and it has a vast network of canyons and riverbeds, and is half the size of Earth.
What is Mars?
Associated with full and new moons which is when Earth, moon, and sun are aligned.
Associated with the first and last quarter when the earth, sun, and moon are at right angles
Highest tidal ranges
Smallest tidal ranges.
These cover most of the areas of the ocean floor.
What are sediments (sand, mud, rocks)?
Gas giants
What are Jupiter, Saturn, Uranus, and Neptune?
The sixth planet from the sun. Early scientists thought it was the only planet with rings, but we now know that all gas giants have rings. It's atmosphere is similar to Jupiter's and it is almost ten times the size of Earth.
What is Saturn?
The interactions and orientations of the sun, moon, and Earth lead to patterns that are evidenced in these?
What are seasons, eclipses, and the phases of the moon?
A small rocky satellite, having about one quarter the diameter of Earth and one-eightieth its mass. It has extremes of temperatures, and no atmosphere or water to support life.
What is our moon?
Ocean water is a complex mixture of these components.
What are gases, water, and dissolve solids?
