plates are present in the case of earth. These plates move in relation to one another at one of three types of plate boundaries: convergent or collisional boundaries; divergent boundaries‚ also called spreading centres; and conservative transform boundaries. Activities like earthquakes‚ volcanic activity‚ mountain building and oceanic trench formation occur along these plate boundaries and the lateral relative movement of the plates varies 0-100 mm annually. Relation between plate tectonics and mountains:

Describe divergent‚ convergent and transform plate boundaries and tell what each results in. * Divergent Plate Movement (plates move away from each other)- Continental and continental‚ oceanic and oceanic. * Convergent Plate Movement (plates move towards each other)- Continental and Oceanic‚ Oceanic and Oceanic‚ Continental and Continental. * Transform Plate Movement

specifically‚ a tsunami can be generated when thrust faults associated with convergent or destructive plate boundaries move abruptly‚ resulting in water displacement‚ owing to the vertical component of movement involved. Movement on normal faults will also cause displacement of the seabed‚ but the size of the largest of such events is normally too small to give rise to a significant tsunami.

The Caribbean Plate is one of the closest boundaries and it is mostly a transform boundary but also has some areas of convergence. Another of the closest boundaries is the Juan de Fuca Plate and it is a convergent boundary. 3.) The most likely of the geologic hazards that could happen to Minnesotans is flooding and the possibility of landslides because of flooding. 4.) The three major

EOSC 114: Volcanoes Notes from Web Notes Lesson 1: Why Do Volcanoes Have Different Characteristics? A. Formation of Lava Magma is formed by melting preexisting rock in Earth’s interior For magma to rise through crust it must be: (1)less dense than the crust (2) runny enough to flow (3) hot enough to stay liquid Magma that cools to form solid rock = lava B. Composition of Magma/Lava Magma is composed of various proportions of: Oxygen‚ Silicon‚ Aluminum‚ Iron‚ Calcium and Potassium Mineral –

The Dynamic Crust‚ Earthquakes and the Earth’s Interior Why is the Earth’s crust described as being dynamic? Crust- solid rock outer zone of Earth The crust is part of the lithosphere. The Earth’s crust is dynamic which means constantly changing. Earthquakes Volcanoes Crustal movements along fault zones Other evidence indicates that parts of the Earth’s crust have been moving to different locations for billions of years. Describe pieces of evidence that suggest minor changes in the Earth’s

series of folds. * Because the plates are being created and are spreading there must be a place where they stop moving; this is the convergent margin. In this zone the advancing edge of a plate meeting another plate causes one to be driven under‚ often with violent consequences‚ creating volcanoes and earthquakes (and possibly tsunamis). * The boundary where the Caribbean Plate meets the Cocos Plate is a fine example of a

Earthquakes and volcanoes are most likely to occur at plate boundaries. 1.1 The structure of the Earth The Earth is made up of four distinct layers: 1. The inner core is in the centre and is the hottest part of the Earth. It is solid and made up of iron and nickel with temperatures of up to 5‚500°C. With its
