Hi! I'm Miriam and this week I'm the Translator.

Projection map: Is a systematic transformation of the latitudes and longitudes of locations on the surface of a sphere or an ellipsoid into locations on a plane. Map projections are necessary for creating maps. All map projections distort the surface in some fashion. Depending on the purpose of the map, some distortions are acceptable and others are not; therefore different map projections exist in order to preserve some properties of the sphere-like body at the expense of other properties. There is no limit to the number of possible map projections.

Distortion: is the alteration of the original shape (or other characteristic) of something, such as an object, image, sound or waveform. Distortion is usually unwanted, and so engineers strive to eliminate distortion, or minimize it. In some situations, however, distortion may be desirable.

Treasure Hunt: is a minor activity in relation to the WebQuest.

In this activity, students should not carry out a complex task, you only need to find answers to some questions given in the content of the links previously selected by the teacher. Sometimes included a global question that requires the student to make a more elaborate use of the information, this is called "the big question".

Treasure Hunt may consist of the following elements: 

- A Brief Introduction on the subject which may include an explanation of the task that the student will perform. 

- A set of more or less difficult questions, depending on the level and age of the students. 

- The "big question" that must be answered after thinking about all the information obtained. 

- Links to web pages where students will find the answers. 

-  An assessment section where you explain how you are going to rate the task performed.

The Earth Ecuador, is the plane perpendicular to the axis of rotation of a planet and passing through its center.

-  Divide the planet's surface into two parts, the northern hemisphere and the southern hemisphere.

-  The latitude of Ecuador is 0 °.

-  The plane of Ecuador "short" the planet's surface on an imaginary line (great circle) which is exactly the same distance from the geographic poles (line equidistant from the North Pole Ecuador and the geographical South Pole).

-  The equatorial circle of the Earth is about 40,075 km. Its radius is 6371 km.

The media are diversified media technologies that are intended to reach a large audience by mass communication.

The technology through which this communication takes place varies.

-  Broadcast media such as radio, recorded music, film and television transmit their information electronically.

-  Print media use a physical object such as a newspaper, book, pamphlet or comics, to distribute their information.

-  Outdoor media -commercial buildings, sports stadiums, shops and buses, blimps, and skywriting.

-  Public speaking and event organizing can also be considered as forms of mass media.

-  The digital media comprises both Internet and mobile mass communication.

-  Internet media provides many mass media services, such as email, websites, blogs, and internet based radio and television

-  The organizations that control these technologies, such as television stations or publishing companies, are also known as the mass media.
