Questions 25

Answers

1
A boundary where two tectonic plates come together or collide ____.
transfer boundary
divergent boundary
transform boundary
convergent boundary
2
Why do scientists believe more earthquakes will occur along the San Andreas Fault?
There has never been an earthquake at that fault line
It is a major fault where pressure has been building
There is so much construction going on
It is the dividing line that may cause California to break
3
Scientist think the inner core is mostly composed of ____.
solid iron
basalt
molten iron
granite rock
4
If 2 plates meet at convergent boundaries and DO NOT subduct, what can happen?
they weather
they fold and crumple
they erupt
they make a fault
5
How does magma pushing up in the Atlantic Ocean changing the ocean floor?
created a long, mountain range below the ocean's surface
produced volcanoes along edges of continents
it produced flat, smooth ocean floor as continents separate
made the Atlantic Ocean waters warmer
6
What is a common secondary effect of a 9.0 magnitude earthquake?
a tornado
a tsunami
global warming
volcanic activity
7
What part of a cracked hard boiled egg represents where earthquakes most likely occur?
at the top where the shell is pointed
along the smoothest part where pieces can't release stress
along the cracks where pieces rub against each other
at the bottom where the shell is the widest
8
Which accurately describes the relationship between earthquakes and volcanoes?
Volcanic eruptions usually cause severe earthquakes
Earthquakes usually cause volcanoes to erupt
Earthquakes and volcanoes are not related in any way
They are often located where tectonic plates meet
9
Why are there many earthquakes along the Pacific Coast?
solar heating
plate movement
erosion
gravity
10
A convection current of magma is made up of ____.
rising less dense liquid and more sinking dense liquid
rising more dense liquid and sinking less dense liquid
liquids of the same density
solids of different densities
11
The inner core is thought to be solid maybe due to extremes in ____.
density
pressure
depth
temperature
12
What drives the movement of Earth's tectonic plates creating earthquakes and volcanoes?
the movement of air currents pushing on the plates
the convection of ocean currents above the plates
the movement of Earth about its axis pulling on the plates
the convection of magma under plates pulling them
13
Why is an area of the world nicknamed The Ring of Fire?
Lithospheric plate boundaries are found in that area
A lot of people live there
The weight of the water forces magma to the surface
It is hotter there than any where else
14
Where is the thickest layer of the earth located?
outer core
mantle
inner core
crust
15
Continental-continental plate collisions produce ____.
deep rift valleys
small island arcs
tall mountain ranges
deep sea trenches
16
Why have fossils been found in South Africa and South America but nowhere else?
Africa and South America may have been part of the same land
In the future, both continents will be together again
Fossils evolved into different organisms
The climate changed to be much colder
17
What was Alfred Wegener's hypothesis?
the continents were part of a large land mass that split
the continents have always been where they are now
the continents are made of rock
the continents will one day form another large land mass
18
Ancient Pangaea may have contained ____.
all of Earth's tectonic plates

Every tectonic plate contains oceanic crust
Every tectonic plate contains a continent
23
Areas that lie above the borders of tectonic plates are characterized by ____.
lack of plant life and animal life
stable temperate climate conditions
frequent earthquake activity
lengthy formations of sea arches
