Venus has a feature named Aphrodite Terra. What is this feature? - CORRECT
ANSWER-a continental-sized plateau
Which of the following contributes to Venus being so hot? - CORRECT
ANSWER-E) All of the above are factors.
What is thought to have caused craters on Venus? - CORRECT ANSWER-Most
are volcanic in origin; some are due to meteoritic impacts.
A characteristic of shield volcanos is the formation of a crater at the summit
which occurs when - CORRECT ANSWER-the lava withdraws and the surface
collapses.
,Which statement is true of Venus' surface? - CORRECT ANSWER-There are two
continent sized uplands.
Why is it reasonable to conclude that the internal structure and evolution of
Venus are basically Earthlike? - CORRECT ANSWER-They have similar masses
and sizes.
In the time between two closest approaches to Earth, Venus rotates almost
exactly five times relative to the sun. The consequence of this is that: -
CORRECT ANSWER-Venus always presents the same face to Earth at inferior
conjunction.
Through radar observations it was found that Venus' - CORRECT ANSWER-
rotation on its axis is retrograde.
Earth's magnetic field - CORRECT ANSWER-prevents charged particles in the
solar wind from reaching the surface.
How is the existence of Earth's unique atmosphere explained? - CORRECT
ANSWER-the oxygen in Earth's atmosphere is a result of early life on Earth
,What drives the motion of tectonic plates on Earth? - CORRECT ANSWER-
convection cells in the mantle
The region around Earth where the magnetic field traps charged particles is the -
CORRECT ANSWER-Van Allen Radiation Belts.
The presence of a magnetic field is a good indication that - CORRECT ANSWER-
we have a liquid metal outer core, spinning rapidly as we rotate.
The principle greenhouse gases in our present atmosphere are - CORRECT
ANSWER-water vapor and carbon dioxide.
How does the greenhouse effect work? - CORRECT ANSWER-greenhouse gases
transmit visible light, allowing it to heat the surface, but then absorb infrared light
from Earth, trapping the heat near the surface
What gas is the primary constitute of our atmosphere? - CORRECT ANSWER-
Nitrogen
From the Earth's center outward - CORRECT ANSWER-the correct order is,
solid metallic inner core, molten metal outer core, silicate mantle and crust.
, The sky is blue because - CORRECT ANSWER-Because molecules scatter blue
light more effectively than red light
The critical part of the atmosphere for protecting life on the ground from
excessive ultraviolet radiation is the - CORRECT ANSWER-ozone layer
When strong solar winds are displaced poleward by our magnetic fields -
CORRECT ANSWER-we get, intense auroral displays
We determine the structure of the Earth's core using - CORRECT ANSWER-
seismic wave data.
Which of the following best describes the lunar maria? - CORRECT ANSWER-
relatively smooth flat plains on the moon
What is true of the Moon's orbital and rotational periods? - CORRECT
ANSWER-They are equal
Which of these theories seems to best explain the Moon's origin? - CORRECT
ANSWER-Impact Theory
