1) Tectonic plates slowly move across the Earth's surface over the course of a year, occasionally crashing into each other. When they crash, it can cause natural disasters like volcanic eruptions and earthquakes. 2) Volcanoes form as magma cools and piles up from cracks in the Earth's crust caused by the movement of tectonic plates and resulting earthquakes. 3) Tectonic plate collisions, though slow, continually form new landforms like mountains and volcanoes as the plates interact within the limited space available.

1. The Tectonic Plates and Volcanoes By: Darien and Kenneth

2. Intro Tectonic plates is not an ordinary plate, it is a plate that covers the whole earth that moves very slowly per year. This tectonic plates when crash against each other creates few of the natural disasters that we know. Examples of the natural disaster caused by tectonic plates are volcanic activity and earthquake.

3. How are Volcanoes created? Volcanoes are natural features that are not put there by accident. There are steps of making a volcano which also applies for the creation of islands. Volcanoes and islands are both created from cooled magma which successively piled up which burst from the earth’s crust. It bursts out because their might be a crack on the earth’s crust because of the movement of tectonic plates and earthquakes.

4. How can Tectonic Plates Make Earthquakes and Volcano Activity? Tectonic plates moves very slowly throughout a year. In a year they only move around 1mm. There are a lot of tectonic plates in this world so even though they only move very slowly they can collide anytime because of the limited spaces they have. Tectonic plates collision forms the landforms that we have today such as mountains and volcanoes.

5. What Cause Volcano to Erupt? Volcanoes explode because the liquid rock (magma or lava) that makes them contains gas. The gas is dissolved in the magma when it is under pressure. When the pressure is removed (by the magma moving close to the surface or by the volcano falling apart, like Mount St. Helens did in 1980) the pressure makes the gas having a greater amount of weight compared to the overlying rocks resulting in blowing the rocks and magma out of the way.
