Teaching English through Geography: Tectonic plates

-

 Around the world, mountains form, volcanoes erupt, and earthquakes shake. Why?

The red dots popping up on the screen are recent earthquakes.

When you see only a few, they may seem like they're all over the place.

But over time you will start to see a pattern.

The Earth's outer shell is divided into pieces called plates. 

Most volcanoes, mountains, and earthquakes occur where plates meet.

Places where plates meet are called plate boundaries.

There are seven major plates along with countless minor plates.

You can see that a plate can be made of both oceanic crust and continental crust.

Interactions between the plates change our planet.

Teaching English through geography:Temperature

 1. Why is the temperature not the same in all places on Earth? Because the Sun is so big compared to the Earth, only the rays that come straight at the Earth will hit it. Areas of the Earth that are hit by direct rays are warmer than areas that are hit by indirect rays. 2.What factors does the air temperature of a place on Earth depend on? A) On the distance of the place from the Equator: the air gets colder as we move away from it and approach the poles (with increasing latitude). B) On the altitude of the place: the air gets colder as we get to a higher altitude. C) On the distance of the place from the sea: The land heats up and cools faster than the sea-so the air above the land is warmer in summer and colder in winter. On the contrary, in the same place, above the sea it is cooler in summer and warmer in winter. 3.What do we call winds and where do they owe their creation? Winds are the lateral and vertical movements of the wind. They are due to: the temperature differences b...

Teaching English through Geography: Parts of a river

  A river is a ribbon-like body of water that flows from high land downhill. It is a geographical feature. Gravity is what causes a river to flow. A river can be wide and deep, or shallow enough. A flowing body of water that is smaller than a river is called a creek or stream. The largest rivers can be thousands of miles long.  As the water flows along the river bed the land is worn away, it erodes. Erosion of rivers can form geologic wonders like the Grand Canyon. All rivers have a starting point where water begins its flow, the source. Water can come from rainfall or snowmelt in mountains, but it can also bubble up from groundwater. The other end of a river is called its mouth, where water empties into a larger body of water, such as a lake or ocean.   A tributary is a river or stream that flows into another stream, river, or lake. The river loses its velocity as it gets lower and deposits different particles or sediments at its mouth. However, rivers still carry i...
