At the equator, the noonday sun appears to __________.

move farther to the south in the fall

Sunlight enters the ocean surface, heating it. Water vapor this generated rises, eventually forming clouds. This reflects some of the sunlight, reducing the heating of the ocean. This is an example of a _____________.

negative feedback

The earth has an ellipsoidal shape (instead of a perfect globe) in large part because ________.

of momentum from spin

The earth is a(n) ____________ when its growth and development is studied over geological time.

open system

The land hemisphere (presently 29% of the earth) erodes, but __________ helps maintain land masses over geologic time.

plate tectonics

The ocean, heated by the sun, warms up, and more of the water evaporates. This increases water vapor in the atmosphere, increasing thermal absorption and re-radiation to the sea, heating it more. This is an example of a ______.

positive feedback loop

The scientific method involves testing hypotheses trying to ________________.

prove them wrong

The sun appears to rise in the east because the earth ______.

rotates about its axis

Mid-oceanic ridges are caused by

sea floor spread and volcanism

Longitude is the ____________.

E-W distance measured in degrees

Seasons are caused by the ______.

The tilt of the Earth's axis

bulges out at the equator primarily due to spin

Time of year is determined by earth's _______________.

changing angle of tilt with respect to the sun
