We refer to plate boundaries as constructive or destructive. Boundaries at which continental and oceanic crust converge are called _________________. At these boundaries the denser oceanic crust, and accompanying material, subducts below the lighter continental crust and dewaters.
11 Δεκ 2023 · The Year 9 package explores the following statement from the Australian Curriculum; ‘The theory of plate tectonics explains global patterns of geological activity and continental movement.’ Materials also focus on evaluation of conclusions. The full package can be downloaded by clicking here.
Relate the occurrence of earthquakes and volcanic activity to constructive and destructive plate boundaries. Consider the role of heat energy and convection currents in the movement of tectonic plates.
Plates interact along plate boundaries. There are three principal types of plate boundary (divergent, convergent, and transform). Plates move apart at divergent plate boundaries such as the oceanic ridge system that separates the North American and Eurasian plates in the north Atlantic Ocean. Plates crash into
Where convection currents converge, plates move towards each other. The movement of the plates, and the activity inside the Earth, is called plate tectonics. Plate tectonics cause earthquakes and volcanoes. The point where two plates meet is called a plate boundary.
Presentation describing the different types of plate boundaries and the features created by interactions between tectonic plates. Links to the videos on the presentation can be found below.
10 Φεβ 2024 · The edges where tectonic plates meet are known as plate boundaries. There are three main types: Convergent Boundaries (Destructive Boundaries or Active Margins): Here, plates move towards each other. Where they meet, they form either a continental collision or else a subduction zone where one plate moves under the other.
