The theory of plate tectonics explains how Earth's continents move. According to this theory, which of the following statements is FALSE?
A. Earth's crust is composed of relatively thin, light plates that float atop the dense, viscous upper layer of the mantle.
B. Ocean basins can grow along divergent boundaries, where the ocean floor splits and spreads apart.
C. Continental plates have relatively stable shapes because they are heavier than oceanic plates and tend to sink below oceanic plates where the two types meet.
D. Many of Earth's mountains resulted from the collision of two continental plates along a convergent boundary.
Areas of the Earth that contain communities composed of organisms that are the product of convergent evolution are called:
a. ecospheres.
b. landscapes.
c. biomes.
d. biospheres.
e. ecosystems.
Which of the following evidence supports the concept of continental drift? Select all that apply.
A. The discovery of large seafloor ridges and trenches formed via plate tectonics
B. Fossils of the same species found in similarly aged complex rock formations across the globe
C. The finding that magnetic poles of major rock formations always align north to south
D. The discovery that magnetic poles of major rock formations do not always align with the Earth’s magnetic poles
