Answer:
4.Now they have some solid evidence. The core is thought to be a two-part construction. The inner core is solid iron, and that's surrounding by a molten core, theory holds. Around the core is the mantle, and near the planet's surface is a thin crust — the part that breaks now and then and creates earthquakes.
6.Pangaea
Pangea, also spelled Pangaea, in early geologic time, a supercontinent that incorporated almost all the landmasses on Earth.
11.A transform plate boundary occurs when two plates slide past each other, horizontally. A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California's earthquakes
13.Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle. (The mantle is the hotter layer under the crust.) Tectonic plates can transport both continental crust and oceanic crust, or they may be made of only one kind of crust.
15.Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.
Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches. The descending end of the oceanic plate melts and creates pressure in the mantle, causing volcanoes to form.
Obduction occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction.[citation needed]
Orogenic belts occur where two continental plates collide and push upwards to form large mountain ranges. These are also known as collision boundaries.
16.When tectonic plates move, it also causes movements at the faults. An earthquake is the sudden movement of Earth's crust at a fault line.
1.A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
2.When magma reaches Earth's surface and erupts from a volcano, it becomes lava.
3.fault
A fault is an area of stress in the earth where broken rocks slide past each other, causing a crack in the Earth's surface. There are the major types of faults: dip-slip normal, dip-slip reverse, strike-slip, and oblique-slip.
5.lithosphere
The lithosphere is the solid, outer part of the Earth, including the brittle upper portion of the mantle and the crust.
7.In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other. He called this movement continental drift.
8.Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials. ... Both abrasion and attrition refers to the wearing down of an object.
9.Igneous rocks
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
10.volcano
noun, plural vol·ca·noes, vol·ca·nos. a vent in the earth's crust through which lava, steam, ashes, etc., are expelled, either continuously or at irregular intervals. a mountain or hill, usually having a cuplike crater at the summit, formed around such a vent from the ash and lava expelled through it.
12.Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth's surface.
14.crust
The outermost layer, called the crust, is solid, too. Together, these solid parts are called the lithosphere. Earth's crust is made up of hard rocks. It is the only part of the Earth that humans see.
15.Inner Core
Inner Core: The innermost part of Earth is the core and is about 1500 miles (2414 km) thick. Both the inner and outer cores consist primarily of iron and nickel.
