Mill and Chill ANSWERS

Question 1ODefine solar system

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

Question 2OList the planets in order from the sun

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

Question 3OGive 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 4ODraw 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 5O What 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 7ODraw and label the

moon phase that comes directly after a waning

gibbousOThird Quarter Moon

Question 8O The 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 9O What 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 10O 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 11O 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 12O 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 13ODefine 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 14O 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 15OSuppose 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
