Answers

1
Where do most earthquakes and volcanoes happen?
in the lower mantle
at the center of a continent
at the center of a plate
along plate boundaries
2
Our 24 hour days are caused by:
the seasons
the revolution of the Earth
the tides and the moon
the rotation of the Earth
3
Which of the following are evidence of the Theory of Continental Drift?
Earthquakes
Different volcanoes on each continent
Same fossils found on different continents
Convection currents
4
How can trees help reduce soil erosion?
they give the soil nutrients
roots absorb the water
they block the sun
roots hold the soil in place
5
The thinnest layer of the Earth is
the inner core
the asthenosphere
the crust
the mantle
6
In the ocean,
warm water is always on the surface
warm water rises, cold water sinks
cold water rises, warm water sinks
cold water is always on the surface
7
A nice, sunny day has high air pressure.
False
True
8
How do tectonic plates move?
convection current in the mantle
the ocean currents push them apart
conduction from the land
they don't move
9
Ocean currents...
cause earthquakes
influence climate and weather
stop periodically throughout the year
affect the rotation of the Earth
10
An area where convection currents rise to the surface of the Earth
Subduction zone
Ocean
Hot spot
Divergent boundary
11
How are igneous rocks formed?
pressure and heat
lava or magma cools and hardens
mineralized by water
lava or magma melts
12
Converging tectonic plates...
will someday cover the Pacific Ocean
Slide past each other to create earthquakes
will pull California into the ocean
move towards each other, cause mountains
13
Cumulus, cirrus and stratus are names of:
comets
precipitation
clouds
rocks
14
What is the Ring of Fire?
an area of volcanoes and earthquakes around the Pacific Ocean
ummm, a song. I fell into a burning ring of fire.....
the hazardous area around a Volcano
an area of lava on the bottom of the Mariana Trench
15
Why is the Atlantic Ocean getting larger?
it isn't
the San Andreas Fault is spreading it apart
hurricanes push ocean currents away from each other
Sea floor spreading is building an underwater mountain chain
16
A rapid release of energy that occurs when stress builds up along plate boundaries or faults is:
a volcano
an earthquake
a hotspot
a subduction zone
17
Which force changes igneous and sedimentary rock into metamorphic rock?
freezing and melting
weathering and erosion
cooling and hardening
squeezing and heating
18
Which answer lists the layers of the Earth from inner to outer?
inner core, outer core, mantle, crust
crust, inner core, outer core, mantle
inner core, crust, outer core, mantle
crust, mantle, outer core, inner core
19
The planet Mercury:
is composed of gases
An outer planet
is the largest planet
An inner planet
20
70% of the Earth's water is found in the oceans
True
False
21
The movement of sediment or soil from one location to another by water, ice or wind is:
deposition
a tornado
erosion
precipitation
22
Saltier water in the ocean...
sinks to the bottom
mixes with fresh water evenly
kills marine organisms
stays at the top
