Question

select all the correct answers. figure 1 shows how earth’s surface looked 250 mya. today, it looks as shown in figure 2. which processes are partially responsible for this change? weathering erosion seafloor spreading lithification subduction

Explanation:

The change from the supercontinent (Figure 1) to current continents (Figure 2) is due to plate tectonics. Seafloor spreading (creates new oceanic crust, moves plates) and subduction (destroys oceanic crust, drives plate movement) are key plate - tectonic processes. Weathering (breaks rocks) and erosion (moves sediments) affect landforms but not continental drift. Lithification (forms sedimentary rocks) is also not related to continental movement.

Answer:

• seafloor spreading
• subduction
