Final Flashcards
How long does it take the earth to complete one orbit ?
365 1/4 days
How earth spins on its axis, causing Day and nigh
Rotation
When it is winter, the United States receives the least direct solar energy, as compared to the rest of the year. Why does this happen
The Northern Hemisphere is titled away from the sun
Which statement best explains the shift in times of high and low tides each day
The moon rises and sets later each day
Which gravitational pull has the greatest effect on tides?
The moons gravitational pull on earth
Which of the moon is in a crescent phase
2 and 8
Eclipses are predictable solar system events. The answer choices below list relative positions of Earth, the sun, and the moon. What position of the Earth, sun and moon are during a solar eclipse.
Sun, earth, moon
When earth moves into the moons shadow, a solar eclipse takes place. What phase of the moon happens during a solar eclipse
New moon
Term that describes the rise and fall of the water level in bodies of water
Tide
Just as Earth moves around the sun, the moon travels around earth. How many earth days does it take for the moon to move around earth
About 28 days
What point would Earth recibe the fewest hours of daylight
Point B
What equation would Cassie use to show the effect of the sun and the moon on spring tides
Sun + moon = spring tides
Tidal range on June 9th
4.76 m
Aside from Earths tilt, what other factor contributes to Earths seasons
The angle of the suns rays and the Humber of hours of daylight
Ann is looking at the sky. There is a first quarter moon. What does she see.
A moon shaped like a half circle
Which is a similarity between a neap tide and a spring tide
Each tide occurs twice a month, and is determined by the pull of gravity of the moon.
The diagram shows the relative position of the sun, moon, and earth. What does the diagram show
A lunar eclipse
Luis created a clay model of earth. To show how Earth rotates, Luis wants to use a toothpick to represent Earth’s axis of rotation. Where should Luis place the toothpick.
Diagonally across Earth, halfway between the equator and the two poles.
Sometimes the moon looks like a crescent. At other times, it looks like a half circle. What makes it possible for you to see the surface of the moon from earth.
Light from the sun reflected by the moons surface
The moon revolves around the earth. The moon travels at a speed of 1 km/s. What keeps the moon revolving around earth
Gravity
Why is the timing of the tides is predictable
The moons path
People put a boat on a beach. They went for a walk. They then came back and the boat was floating offshore. What happend
The water level rose due to high tide
How are the sun, earth, and moon aligned when spring tides occur
The sun, Earth, and moon form a straight line
How do temperatures at the Earths equator compare to the temperatures at the poles during the year
There is less variation
The phases of the moon change the appearance of the moon, as seen from earth. Which happens after a third quarter moon
Waning crescent
Which position of the moon results in a solar eclipse
2
How often does the moon pass over a particular spot on the earths surface, causing tides as a result of it’s gravitational pull
Once every 24 hours and 15 minutes
Which question do you ask to find out a planets year
How long it orbits the sun
Kevin travels to Australia for the winter, but it is more like summer. Why is this
The Southern Hemisphere is tilted towards the sun, so it is summer in Australia.
The rotation of Earth on its axis causes every location on the surface of Earth to move as earth turns. In which direction does each location move
From west to east
What defines season
A specific time of the year that is characterized by reoccurring weather conditions.
Once a month, Earth passes between the moon and sun. Is a solar eclipse possible during this time
No, because full moons happen when earth is between the moon and sun, and solar eclipses only happen during new moons
What is emitted from Alpha decay
Two protons and two neutrons from the nucleus
What type of radioactive decay does not change the atomic number because of low penetration
Gamma

Protons, neutrons
The smaller the number is an elements box on the periodic table tells you the elements
Number of protons
The smaller number in an element box lists the elements
Atomic number
What is not a for, of radio activity
Delta
Which particle could pass through paper
Beta
Which of the following supports the info above
The rotation of the sun is quite different from the rotation of the earth, since they rotate at different rates
When two atomic nuclei combine
Nuclear fission
Nuclear energy to produce electrical energy
Nuclear fission
