This piece of space junk orbits between Mars and Jupiter.
This type of space junk has a highly elliptical path.
This type of space junk does not burn up in our atmosphere.
65 million years ago a disaster happened, although we are not sure of the cause. All the dinosaurs and many other groups of animals and plants became extinct around this time. The most popular theory is that a mountain-sized meteorite hit the Earth, throwing up a thick cloud of dust and causing tidal waves and global forest fires. The dust hid the Sun. This might have killed many plants, which need light to live. It might also have cooled the Earth and so killed the dinosaurs which, being unable to keep themselves warm, might have stopped moving and so starved.
(It impacts the Earth.)
This type of space junk can be composed of rock, metal, or both.
This type of space junk is composed of frozen gas and dust AND may orbit in the Oort Cloud or Kuiper Belt.
Star’s that are this color have a cooler temperature.
Stars begin their life in a stellar nursery called ________
Small Stars like our sun end their life as a _________ then a _________.
White dwarf then black dwarf
How long a star lives depends on
The original mass of the star.
The largest type stars will end their life as
The Earth moves from daylight to darkness once every day due to fact that it is
The Earth will make one trip around the sun each year. This movement is called
Earth is farthest from the Sun at its aphelion (summer in the Northern Hemisphere) and closest during its perihelion (winter in the Northern Hemisphere).
In which direction do both the Earth and Moon rotate and revolve
In the spring and fall the sun is directly over _______
It is overhead at the equator during the Spring and Fall equinoxes. The Sun is overhead at the Tropic of Cancer on June 21. This is the furthest north that the strongest rays will travel. It is overhead at the Tropic of Capricorn on December 21.
The three reasons for the seasons are
The tilt of the Earth, revolution around the sun, direct/indirect light that reaches Earth’s surface. ***Notice how the location of the most direct rays change as the Earth revolves around the sun.
What conditions are necessary for a spring tide to occur?
The positioning of the sun and the moon also has an effect on the height of the tidal swell. During a new or full moon phase, the sun and moon are in line, pulling on the earth's surface. This creates a higher level of tide - called the "spring tides" from the Welsh word "springan" meaning 'to bulge'.
What percentage of the moon is always illuminated?
The image is a model of ??
Solar Eclipse. A solar eclipse can occur when there is a new moon. This does not occur every month because the moon's orbital plane doesn't "lie flat" along the ecliptic, but forms an angle of about 5º as you can see in this diagram (note: the distances in this diagram are not to scale).
This image is an example of ????
A waning crescent moon
The phases of the moon are due to ________
The position of the Earth, Sun, and Moon.
**Light on right, moon is getting bright.
The unit of measurement that scientists use to measure distances in space.
The closest star to the earth, not counting our own sun, is Alpha Centauri. This star, our solar system's closest stellar neighbor is 4.3 light years away from the earth! This means that the closest star to the earth (besides the sun) is >>>> 23,462,784,000,000 miles away from us!
Distances in space are huge and if we used miles or kilometers our data (numbers) would be huge. One light year is equal to an extremely long distance - 5,865,696,000,000 miles to be exact!
Galaxies are classified by ??
Their shape. The Milky Way Galaxy is a spiral galaxy.
Billions of stars clustered together are called???
This is a picture of an irregular galaxy.
What two forces keep our planets in orbit around the sun?
Gravity and Inertia (sideways motion in image).
Why can Hubble take clearer pictures that Earth based telescopes?
It is above our “pesky” atmosphere.
