The slow lateral movement of large segments of the outer solid earth is
a. Mainly due to the earth’s rotation
b. One obvious feature of plate tectonics
c. Gravitational attraction of the Sun and Moon
d. Associate it with the earthquakes but not volcanoes
e. Speeding up because of human-induced changes
f. Caused by contraction of the earth as it cools
b. One obvious feature of plate tectonics
How can the earth systems help with deal with the problems of human induced global change?
We can use this information to inform humans on the consequences so that we may implement corrective actions
The growth of the planet by gathering in pieces from the whirling primordial disk is commonly called
a. Supernova
b. Planetary accretion
c. Solar nebula
d. nuclear fusion
e. The rock cycle
f. Gravitational collapse
b. planetary accretion
From what we know today, all the following things make the earth unique among the planets, except:
a. the active biosphere
b. abundance of H2O in all three forms
c. the tectonically active surface
d. the dense core of iron
e. abundance of oxygen in atmosphere
d. The dense core of iron
Most of the rock samples brought back from the moon
a. indicated that the moon is much younger than her
b. indicated that the moon is far older than the earth
c. show only subtle differences from familiar earth rocks
d. resemble meteorites more than they resemble earth rocks
e. contained many fossils never seen before on earth
c. Show only subtle differences from familiar earth rocks
We commonly quote a figure of 4.6 billion years for the age of the earth, although we still haven’t found an age date this old for any rock sample of our planet, and few age states that even come close. However, rocks from the moon yield such old ages comparatively easy. Why? Explain in a few words
Unlike the earth, the moon has no atmosphere to weather rocks or plate tectonic activity to destroy rocks

d. Neil Armstrong
e. Leonardo da Vinci
f. Frederick Vine
b. Alfred Wegener
New continental crust is produced chiefly at
a. mid ocean ridges
b. intracontinental rift valleys
c. convergent plate margins
d. transform faults
e. hotspots
a. Mid ocean ridges
The most accurate reconstruction of Pangaea would result from matching together along the
a. shorelines of continents
b. traces of transform faults
c. bases of continental slopes
d. centres of oceanic trenches
e. summits of oceanic ridges
a. Shorelines of continents
A Himalayan or alpine type boundary would be
a. convergent, with continental crust on both sides
b. divergent, with continental crust on both sides
c. transform, with continental crust on at least one side
d. convergent, with continental crust against oceanic crust
e. Convergent, with oceanic crust on both sides
a. convergent, with continental crust on both sides
Why did it take so long for the idea of drifting continents or mobile lithosphere to gain general acceptance?
The continental drift hypothesis provided no mechanism to explain how the continents moved
To be classified as a mineral in the geological sense, a substance must meet all the following requirements except
a. be naturally formed
b. Possess economic or nutritional value
c. Have a definite chemical formula
d. Have a definite crystal structure
e. be a solid material
b. Possess economic or nutritional value
Can we consider ice to be a mineral or rock? Explain briefly
If ice is formed naturally then it is a mineral

d. nonconformity
e. hiatus
d. varve
c. angular nonconformity

a. Younger than 500 million years
b. 500 million years
c. Older than 500 million years
d. pleistocene
e. cretaceous
f. Jurrasic

Identifies three human activities in the region where you live that are causing changes in the environment
- Deforestation
- Burning of fossil fuels
- Water pollution
Briefly, what is the difference between a geocentric and heliocentric solar system?
A geocentric solar system puts the earth at the center of the universe whereas a heliocentric solar system puts the sun at the center of the universe
Briefly, what is the difference between physical and chemical weathering?
Physical weathering affects the structure of a rock, not composition
Chemical weathering alters the chemicals the rocks are composed
Briefly, what is the difference between the relative and absolute age of a rock layer?
Relative age refers to the age of a rock layer compared to other layers.
Absolute age refers to the actual time in years
Briefly, what is the difference between magma and lava?
Magma is composed of molten rock, stored in Earth’s crust
Lava is magma that reaches the surface through a volcano vent
