The plate tectonics theory states that…
Continental crust “plows through” oceanic crust
Seafloors or ocean floors move and carry the continents.
Earth's lithosphere is composed of a massive slab of rocks called plates which moves at 10 cm a year.
The relative position and shapes of continents as a result of continuous movement of plates of Earth’s crust.

The Theory of Continental Drift was ____________
Based on the observations of the distribution of rock types, fossils, and structures in some continents.

Which of the following statement is TRUE about Pangaea Ultima?
It means "Last Pangaea."
A prediction to appear approximately 250 million years from now.
An American Professor predicted Pangaea Ultima, and Geologist named Christopher Duque in 1982.
All statements are TRUE.
How will you differentiate Mohorovicic discontinuity and Gutenberg discontinuity?
Mohorovicic discontinuity is the boundary between the upper mantle and the crust, while the Gutenberg discontinuity is the boundary between the lower mantle and outer core.
The Mohorovicic discontinuity is located about 2900 km below the Earth's surface, whereas the Gutenberg discontinuity is 8 km below the ocean floor and 30 to 50 km beneath typical continents.
The Gutenberg discontinuity separates the liquid outer core and the earth's solid inner core, while Mohorovicic discontinuity marks the boundary between the lower mantle and the outer core.
Mohorovicic and Gutenberg discontinuities are the boundaries of the Earth's layers.
Which type of plate boundary produces earthquakes?
Convergent Plate Boundary
Divergent Plate Boundary
Transform Plate Boundary
All options are correct
What do you call the mineral formed in the Mantle?
Diamond
Quartz
Mercury
Dolomite
Which of the following discontinuity separates the lower liquid core and solid upper core?
Gutenberg Discontinuity
Lehmann Discontinuity
Mohorovicic Discontinuity
Plate Boundaries
What are the two (2) elements present in the Earth's core?
Iron and Lead
Iron and Nickel
Nickel and Lead
Nickel and Carbon
Which of the following statement is FALSE about the oceanic plate and continental plate?
The oceanic plate is denser than the continental plate.
The oceanic plate is mainly made up of basalt rocks, while the composition of the continental plate is granite rocks.
The continental plate is thinner than the oceanic plate.
Both oceanic and continental plates are plates that come together, spread apart, and interact at boundaries all over the planet.
Why did scientists reject Wegener’s idea of Continental Drift?
He cannot explain what causes the continents to drift.
He explains that South America and Africa fit together like a puzzle.
He described that the rocks and mountains at the edges of the continents were similar.
He explains that fossils of ancient plants such as "Glossopteris" can be found in almost all continents
Imagine that you are in the middle of an island and found that there is a rift valley. What type of plate boundary exists on that island?
