Exploring Evidence of Plate Movement

Which continents are noted for appearing to fit together?

• Asia and Africa

• South America and Africa

• Australia and Antarctica

• North America and Europe

What was the initial clue that suggested continents were once connected?

• Similar rock formations

• Fossil evidence

• Climate patterns

• The shape of the continents

What geological feature in the Atlantic Ocean suggested plate movement?

• Deep ocean trench

• Mid-Atlantic ridge

• Large island chain

• Submarine canyon

What is the significance of underwater volcanic activity along the mid-Atlantic ridge?

• It is unrelated to plate tectonics

• It suggests the ocean floor is expanding

• It indicates the presence of hotspots

• It proves the existence of deep-sea creatures

What does the alignment of magnetic rocks indicate?

• Earth's magnetic field has reversed over time

• Magnetic rocks always align north-south

• Magnetic rocks are not influenced by Earth's magnetic field

• Earth's magnetic field has never changed

What does the reversal of Earth's magnetic field tell us?

• Magnetic reversals affect the ocean's tides

• The magnetic field has flipped multiple times

• Magnetic reversals cause earthquakes

• The Earth is slowly losing its magnetic field

What provides conclusive evidence of seafloor spreading?

• Continental drift theory

• Presence of mid-ocean ridges

• GPS measurements of plate movement

• Symmetrical magnetic striping on the ocean floor

What does the symmetrical arrangement of magnetic stripes on the ocean floor indicate?

• Impact of meteorites

• Random geological processes

• Seafloor spreading due to plate tectonics

• The ocean floor is static

How are modern plate movements measured?

• Studying fossil records

• Through satellite GPS technology

• By mapping ocean currents

• Using deep-sea drilling

At what rate do most tectonic plates move?

• 10 meters per year

• 5 km per year

• 100 cm per year

• About 1 cm per year
