Mill and Chill ANSWERS

Question 1

ODefine solar system

OThe solar system is the collection of large and small bodies that orbit our central star, the sun.

Question 2

OList the planets in order from the sun

OMercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

Question 3

OGive 2 characteristics of an inner planet and 2 characteristics of an outer planet

OInner- smaller, closer to sun, little to no moons, rocky

OOuter- larger, farther from sun, many moons, gaseous

Question 4

ODraw a diagram that shows the position of Earth at four

different times during the year (summer, spring, fall, and

winter) and label each season. Be sure to include the tilt and

the sun in your diagram.

Answer

Question 5

OWhat is happening in the Arctic Circle during the December Solstice?

O People in that area are experiencing 24 hours of

darkness

Question 6O Kevin travels from the U.S. to

Australia for the summer, but when he gets there it feels more like

winter. Explain this!

O In the US which is in the Northern hemisphere, it is tilted toward the

sun causing summer to occur, however Australia is in the Southern hemisphere which is tilted away from

the sun causing winter to occur.

Question 7

ODraw and label the moon phase that comes directly after a waning

gibbousOThird Quarter Moon

Question 8

OThe cycle of the moon’s phases repeats in a

predictable way. About how long does it take to cycle from one full moon to the next full moon? O About 28-29 days

Question 9

OWhat time does a full moon rise and set?

OWhat time does a new moon rise and set?

O Full moon rises at 6pm and sets at 6am and a new moon rises at 6am and sets at 6pm

Question 10

O Which is a similarity between a neap tide and a

spring tide? O Both are caused by the

gravitational pull of the moon and occur twice a

month

Question 11

O How is a solstice different from an equinox?

O Solstice is when one hemisphere receives the maximum amount of

sunlight while the other hemisphere receives the

minimum. During an equinox, both hemispheres receive sunlight

equally.

Question 12

O How much times passes between neap tides at a location? Explain why!

O Neap tides occur every 14 days because it takes 14

days to get from one quarter moon to the next.

Question 13

O Define tidal range. How do you calculate it?

O Tidal range is the difference between the levels of ocean

water at high tide and low tide. You subtract the water level at low tide from high tide to find

the tidal range.

Question 14

O What has the greatest gravitational pull on the

tides? Why?OThe moon has the greatest

gravitational pull because it is the closest to Earth

Question 15

OSuppose you were an astronaut in the middle of the near side of the moon during a full moon, what would Earth look like? OEarth would be dark

because it would be experiencing nighttime
