Sci Chapter 5 Lesson 8: Ocean Drilling as Evidence for Plate

Based on the theory of seafloor spreading, what would be expected of ocean floor samples found near the Mid-Atlantic Ridge?

• Rocks of the same age throughout the entire area
• No rocks would be found near the ridge
• Older rocks near the ridge and progressively younger rocks farther away
• Younger rocks near the ridge and progressively older rocks farther away

What is the name of the underwater mountain range that runs from Iceland to Antarctica?

• Arctic Ridge
• South Pacific Ridge
• Antarctic Ridge
• Mid-Atlantic Ridge

Which of the following best describes the theory of plate tectonics?

• The study of different types of rocks
• The process of water erosion on land
• The movement of the moon around the Earth
• The movement of Earth's outer shell in plates

What was the Deep Sea Drilling Project (DSDP)?

• A program to study the atmosphere of Mars
• A project to explore the surface of the moon
• An ocean drilling project designed to analyze the ocean floor

• A drilling initiative to study the Earth's core

Which statement best describes the theory of sea floor spreading?

• The theory of sea floor spreading is a result of tectonic plates colliding
• Sea floor spreading occurs due to the melting of polar ice caps
• The theory of sea floor spreading is caused by the gravitational pull of the moon
• New oceanic crust is formed through volcanic activity and then gradually moves away from the mid-ocean ridges, creating new sea floor.
