Sea Floor Spreading Worksheet with Answers

Sea floor spreading is an important concept in the study of geology. It describes the process by which new oceanic crust is formed at mid-ocean ridges, and existing crust is destroyed at subduction zones. Sea floor spreading worksheets are a great way to learn more about sea floor spreading and its related processes. These worksheets provide a comprehensive overview of the various aspects of sea floor spreading and its related features. The worksheets also provide answers to questions related to the topic.

What is Sea Floor Spreading?

Sea floor spreading is a process of plate tectonics where new oceanic crust is formed at mid-ocean ridges and existing crust is destroyed at subduction zones. The process of sea floor spreading is driven by convection currents in the Earth’s mantle, which cause the lithospheric plates to move. As the plates move, they create new oceanic crust at mid-ocean ridges, which are underwater mountain ranges. This new crust is pushed away from the ridge as the plates move, which results in the formation of new seafloor.

How Does Sea Floor Spreading Occur?

The process of sea floor spreading is driven by convection currents in the Earth’s mantle, which cause the lithospheric plates to move. At the mid-ocean ridges, these convection currents cause the plates to move apart, allowing magma to rise up and fill the gap. This magma cools and solidifies, forming new oceanic crust. The newly formed crust is then pushed away from the ridge by the movement of the plates, which results in the formation of new seafloor.

What are the Effects of Sea Floor Spreading?

Sea floor spreading has a number of important effects on the Earth’s surface. One of the most important is that it causes the continents to move and drift apart over time. This process is known as continental drift and it is responsible for the formation of new landmasses and the separation of existing ones. Sea floor spreading also leads to changes in ocean circulation patterns, as new seafloor is continually pushed away from the ridge. This can have a significant effect on climate, as it affects the amount of heat and moisture that is exchanged between the atmosphere and the ocean.
