Geografy of Earth
Dylan Valeria Paula Angelline
Geography as a discipline can be split broadly into two main subsidiary fields: human geography and physical geography.

The crust is the outer layer of the earth. It is a thin layer between 0-60 km thick. The crust is the solid rock layer upon which we live.
Different exam boards and textbooks may use different names for each of the boundary types. For example, a destructive boundary may also be called a collision boundary. Use any term so long as you use it correctly, but it is best to stick to the terms you have been taught.
At a tensional, constructive or divergent boundary the plates move apart.
At a compressional, destructive or convergent boundary the plates move towards each other.
At a conservative or transform boundary the plates slide past each other.
The Earth's crust is broken up into pieces called plates. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other. The movement of the plates, and the activity inside the Earth, is called plate tectonics.
Plate tectonics cause earthquakes and volcanoes. The point where two plates meet is called a plate boundary. Earthquakes and volcanoes are most likely to occur either on or near plate boundaries.
The map shows the world's tectonic plates and the distribution of earthquakes and volcanoes.

the Earth is composed of a solid inner core outher core mantle asthenosphere lithospher and crust
convection is the engine driving the motions of lithosphere and crust.
Earths land regions
there are four main types of land regions .
mountains , highlands , plateus , and plains
Mountain and Highland regions
these are areas of land that rise avobe the sea level
Plateus
Plateus are highlands that are still flat .
Plains
These are flat lands that are very close to the sea level .
Earths climate regions
not all land regios are the same becaus they not all of them have the same climate.
some are coold , some are hot etc .
The total population of Earth is around 5.5 billion people divided into 6 continental categories.
They are 8 types of natural hazards.
The Earth is compresed of 14 rigid continental and oceanic tectonic plates
