In what category of layers of earth are the following : lithosphere, asthenosphere, mesosphere, outer and inner core?
Compositional
Continental
Mechanical
Geological
What is the layer of Earth that composed of nickel-iron alloy?
crust
core
mantle
mesosphere
How do rocks in asthenosphere can easily deform compare to lithosphere?
Because asthenosphere can be found above lithosphere.
Because the rocks in asthenosphere are mostly nickel.
Because the lithosphere has greater pressure compare to asthenosphere.
Because of extreme pressure and temperature to asthenosphere than lithosphere.
Which layer of Earth generates Earth's magnetic field
Crust
Mantle
Inner core
Outer core
Which of the following geologists proposed the Continental Drift Theory?
Alfred Wegener
Abraham Ortelius
Alexander van Humboldt
Antonio Snider-Pellegrini
According to Continental Drift Theory, how do geologist come up with the word "Pangaea"?
He proposed that the Earth originated as a single, huge landmass.
He proposed that some of the land on Earth submerged in ocean.
He proposed that once Earth revolve around the sun, land are automatically separating from each other.
Based on the given illustration, how it could be one of the useful evidence for Continental Drift Theory?
Continents are fit together
There are some fossils on different continent
Mountain ranges can be found with other continent
What will be the sign of new seafloor spreading in oceanic lithosphere?
Once two lithosphere move apart from each other
Once the magma rises from the mantle
Once the fill the gap between two plates
Once the magma readily cools and solidifies
What do we call to a process where Earth's magnetic pole switches to another pole?
geological magnetic attraction
geomagnetic reversal
geomagnetic attraction
geomagnetic motion
When will be the time that rocks in lithosphere possess weak magnetism?
normal polarity
reverse polarity
normal attraction
reverse attraction
