Presentation on Convergent Plates
General objective of this lecture is to present on Convergent Plates. In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction),…
Geography
Tectonic Plate Types
There are three kinds of plate tectonic boundaries: divergent, convergent and transform plate boundaries. Convergent – plates move toward one another. Divergent – plates move away from each other. Transform…
Flood Basalts
Principle purpose of this lecture is to present on Flood Basalts. Basalt is a type of rock that is produced from the mantle. Flood basalts are yet another…
Lecture on Ocean Forces
This lecture introduce on Ocean Forces. Ocean Currents are influenced by two types of forces; 1. Primary Forces–start the water moving. The primary forces are: Solar Heating, Winds, Gravity and Coriolis effect. 2. Secondary…
Presentation on Tectonic Plates
This lecture introduce on Tectonic Plates. Today plate boundaries are determined by examining the location of volcanoes and earthquakes. Volcanoes result from the friction (heat) of the plates motion. Earthquakes occur…
Presentation on Earthquakes
Main objective of this lecture is to present on Earthquakes. Earthquakes are a result of motion within the earth. This only occurs where the earth is solid and…
Presentation on Volcanoes
Volcanoes are the result of hot spots within the crust or mantle of the earth. The hot, liquid rock will break through weak spots in the…
Lecture on Plate Tectonics
Major purpose of this lecture is to present on Plate Tectonics. Plate tectonics is the theory that Earth’s outer shell is divided into several plates that glide…
Earth Materials – Geology Plate Tectonics
Major purpose of this lecture is to present on Earth Materials – Geology Plate Tectonics. Evidence of Plate Tectonic plates: Same fossils and rocks found in different parts of…
Examples of Earth Resources
Prime objective of this lecture is to present on Examples of Earth Resources. The natural resources of the Earth can provide us with everything we need to…
Resources of Our Earth
The aim of this lecture is to present on Resources of Our Earth. A resource is something that we can get from the earth over and over…
Wind Direction of Ocean
Basic purpose of this lecture is to present on Wind Direction of Ocean. A wind blowing for 10 hours across the ocean will cause the surface waters…
