Question

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

Explanation:

Weathering breaks down rocks on Earth's surface. Erosion transports the weathered material. Seafloor spreading is related to plate - tectonics and the creation of new oceanic crust. Lithification is the process of turning sediments into sedimentary rocks. Subduction is when one tectonic plate moves under another. The change from Earth's surface 250 MYA to today is due to plate - tectonic processes (seafloor spreading and subduction) and surface processes (weathering and erosion). Lithification is more about rock - formation rather than large - scale surface change over this time frame.

Answer:

weathering, erosion, seafloor spreading, subduction
