1-LAYERS OF THE EARTH -CRUST MANTLE, CORE

Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person. In fact, the deepest humans have ever drilled is just over 12 kilometers (7.6 miles).
The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface.

2. Panginoon , maraming Salamat po sa dakilang araw na ito . Kami po ay nagpupuri at niluluwalhati ang inyong mga kaloob na biyaya sa amin. Gabayan po ninyo kami sa aming pag - aaral at sa pagtuklas ng bagong kaalaman na magtataguyod sa amin upang maging mahusay mong tagapaglingkod . Ipadala po ninyo ang inyong banal na espiritu upang magningas sa puso ng bawat isa sa amin ang maalab na pagnanais na maging isang mahusay na mamamayan , na may malasakit sa pamilya , kapwa , kalikasan at sa mahal na bansang Pilipinas . Ang lahat ng ito ay hinihiling namin sa matamis at dakilang pangalan ni Hesus na aming tagapagligtas . Amen.

6. LAYERS OF THE EARTH

7. EARTH’S STRUCTURE The earth can be divided into four concentric zones (Figure ). The innermost is called the  inner core  and is thought to be a solid, spherical mass of iron. Its radius is about 1,216 kilometers (730 miles). The next zone, called the  outer core , is believed to be a layer of molten liquid rich in nickel and iron that is about 2,270 kilometers (1,362 miles) thick. The outer core is overlain by the  mantle , which is a solid yet puttylike rock that can actually flow. The mantle is about 2,900 kilometers (1,740 miles) thick. The  crust , the outermost zone, is the hardened exterior of the earth and varies in thickness from about 5 to 50 kilometers (3‐‐30 miles).

8. THE CRUST  The  crust  is the outermost solid shell of which is chemically distinct from the underlying mantle. The Earth's crust is composed of distinctly different  continental crust  and  oceanic crust , which have different chemical compositions and physical properties, and which were formed by different geological processes.

9. continental & oceanic crust The  continental crust  is the layer of  granitic ,  sedimentary , and  metamorphic rocks  which form the  continents  and the areas of shallow seabed close to their shores, known as continental shelves. Oceanic crust  is the uppermost layer of the  oceanic  portion of a tectonic plate.

10. THE MANTLE The Mantle is the second layer of the Earth.  It is the biggest and takes up 84 percent of the Earth.  In this section you will learn and more about how hot the mantle is, what it is made of, and some interesting facts about the Mantle .

12. THE OUTER CORE The Outer Core is the second to last layer of the Earth.  It is a magma like liquid layer that surrounds the Inner Core and creates Earth's magnetic field. 

13. THE INNER CORE The inner core is located at the center of the Earth and is composed of nickel and iron. It is mostly solid.

14. TECTONIC PLATES A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.

15. DIVERGENT BOUNDARY a  divergent boundary  or divergent  plate  boundary  (also known as a constructive  boundary  or an extensional  boundary ) is a linear feature that exists between two tectonic plates that are moving away from each other.

16. CONVERGENT BOUNDARY a  convergent boundary , also known as a destructive plate  boundary , is a region of active deformation where two or more tectonic plates or fragments of the lithosphere are near the end of their life cycle.

17. TRANSFORM BOUNDARY A  transform  fault or  transform  boundary (also known as a conservative  plate  boundary, since these faults neither create nor destroy lithosphere), is a type of fault whose relative motion is predominantly horizontal, in either a sinistral (left lateral) or dextral (right lateral) direction.
