q1 the earth has spheres that are constantly interacting. which of the following is the best example of the geosphere interacting with the biosphere?

a.

volcanic ash provides nutrients in the soil for plants.

b.

some land mammals are dependent on ice formations.

c.

a strain of bacteria is able to live deep in an ocean.

d.

strong winds carry pollen across large fields to flowers.

q2 the earth has a mass of about 6 × 1024 kg and orbits about the sun. as it orbits, it moves at over 60,000 miles per hour. with such great mass and speed, what keeps the earth from moving away from the sun and out of the solar system?

a.

the amount of heat that is continuously released from the sun

b.

the sun's rate of rotation

c.

the sun's gravitational force

d.

the speed at which the sun moves in the galaxy

q3 the location labeled x is located near an ocean. which of the following best describes what the models show?

a.

the earth experiences different tides based on the variation of the moon's mass.

b.

the moon's rotation affects the tides experienced by different locations on earth.

c.

the earth's tides vary in different locations based on the moon's position.

d.

the moon's orbit causes all parts of the earth to experience the same strengths of tides.

q4 the jet stream is often showed on weather maps, and varies in its location. the thick line on the map represents the jet stream on a winter day. two towns, labeled x and y on the map, are located near the jet stream.

based only on the information given, which statement best describes the weather for one of the towns?

a.

it is warmer and dryer than normal for winter in town y.

b.

it is warmer and dryer than normal for winter in town x.

c.

town x is experiencing lower atmospheric pressure than nornal for winter.

d.

town y is experiencing higher atmospheric pressure than nornal for winter.

q5 the earth's surface is affected by the sun in many ways. the diagram below shows the earth and sun's light rays during a certain time of the year.

which of the following best describes what people are experiencing at location x on earth?

a.

the season with the longest days

b.

the first days of fall

c.

the coldest season of the year

d.

the first days of summer

q6 the sun, earth, and moon interact in many ways. the image below shows an alignment of the sun, earth and moon.

what is happening as the moon passes from position 1 to position 3?

a.

a third quarter moon

b.

a new moon

c.

a lunar eclipse

d.

a solar eclipse

q7 certain weather patterns are evident near the equator. the image below shows some processes that can cause these specific weather patterns.

which of the following best describes what the image shows?

a.

rising heat due to the sun's energy results in a constant pattern of the trade winds.

b.

fair weather patterns cause the trade winds to sink down toward the ocean surface.

c.

sun-heated air rises which is replaced by hotter air resulting in a high pressure zone.

d.

energy absorbed by the earth due to warm water currents results in high pressure zones.

q8 different regions of the united states have different weather patterns. eureka, california and middletown, new jersey are both located on a coast at about the same latitude. the map shows the location of the cities near 40°n latitude, which is represented by the dashed line.

eureka has an average july temperature of 17°c (63°f). middletown has an average july temperature of 28°c (82°f). if wind patterns generally move from the west toward the east, why is eureka so much cooler than middletown in july?

a.

land loses its heat slower than water, so middletown receives hotter air than eureka throughout the year including during the summer months.

b.

ocean water remains cooler longer than land, so air from the ocean moving east toward eureka keeps temperatures lower than in middletown.

c.

euereka is much further away from the equator than middletown is, so the cold air from the north keeps the temperatures lower.

d.

the pacific ocean contains more salt than the atlantic ocean, so colder ocean currents from the pacific keep eureka's temperature lower than in middletown.

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
