Part 1. General geography. Geographic cover.
Lesson 1
Theme: Lithosphere and the Earth’s crust.
Plan:
1. Structure of the earth
2. Asthenosphere and lithosphere
3. Continental and oceanic earth’s crust
Structure of the earth
Earth structure includes crust, mantle, core, hydrosphere, atmosphere, magnetosphere.
The Core is the inner part of the earth, it is the center of the Earth; it’s under extreme pressure. It consists of iron and nickel. Relative temperature is from 2,000C to 5,000C. Density: 10 to 13 times denser than water. What does the core consist of? OUTER CORE is area of molten metal that surrounds the inner core. Because the earth rotates, the outer core spins around the inner core and that causes the earth's magnetism. It is in liquid state. INNER CORE is a dense ball of iron and nickel, because of the intense pressure this part is in solid state.
The Mantle is the portion of the interior beyond the crust. It begins about 6 miles (10 km) below the oceanic crust and about 19 miles (30 km) below the continental crust. It consists of silicon, oxygen, iron, and magnesium. Relative Temperature varies from 870C to 2,200C. Density: 3.3 to 5.5 times denser than water. Upper portion of the mantle is considered to be extending up to 400 km. It is the main source of magma that finds its way to the surface during the volcanic eruption. It has a density higher than the crust (3.4g/cm).
