The model builds on the concept of continental drift , an idea developed during the first decades of the 20th century. The geoscientific community accepted plate-tectonic theory after seafloor spreading was validated in the late s and early s. The lithosphere, which is the rigid outermost shell of a planet the crust and upper mantle , is broken into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates depending on how they are defined and many minor plates. Where the plates meet, their relative motion determines the type of boundary: convergent , divergent , or transform. Earthquakes , volcanic activity , mountain -building, and oceanic trench formation occur along these plate boundaries or faults.
Science Scope—January Volume 43, Issue 5. The generation of mountains, deep-sea trenches, volcanic chains, island arcs, and rift valleys can be explained by plate motions. Plate tectonic theory even unites the ideas of sea-floor spreading, subduction, and mantle convection. This article describes a classroom activity that allows students to discover plate interactions as the connection among seemingly different features and processes in geology. To introduce the activity, students may be shown images of Mesosaurus , Glossopteris , volcanoes, coal, and earthquake destruction. In the eyes of students, Mesosaurus fossils look similar to the bones of an alligator or crocodile.
Describe the sequence of steps involved in using water stored behind dams to generate electricity. He lobbied the British Parliament year after year to no avail until his death in Exercise 3 Students' own answers. What features form where two plates converge? Directions: In each part of the circle, write the number of the statement that best describes each landform.
Thursday, October 30, Acids can corrode some natural materials. Acids have pH levels lower than 7. Also called a scoria cone. Also called an extensional boundary. Also called the Somali Peninsula.
This activity has received positive reviews in a peer review process involving five review categories. The five categories included in the process are. Students participate in a jigsaw activity to learn about types of plate boundaries, becoming an expert in one of five global datasets - earthquakes, volcanoes, seafloor age, topography, and gravity - and then sharing their expertise to build connections between the different datasets.

Plate tectonics is the grand, unifying theory of Earth sciences, combining the concepts of continental drift and sea-floor spreading into one holistic theory that explains many of the major structural features of the Earth's surface. It explains why the oceanic lithosphere is never older than about Ma and why only the continents have preserved the Earth's geological record for the past Ma.
in this activity might be applied to the Earthquake Focus and Epicenter Movement along a Where Plates Collide Some volcanoes form because of collision.
Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes. Much of the content is the same. The full original lesson can be found here. Show students pieces of a jigsaw puzzle or have them think of what puzzle pieces look like. Lead learners in a discussion about how puzzle pieces work.
Learning and teaching resources on the fundamentals of plate tectonics and the basics of earthquakes are provided in this section.
