1. Answer the questions below:
2. Complete the fact sheet:
Earth's size and shape…
A Sphere…
Earth's Radius …
6,353 km to 6,384 km…
3,959 mi 
6,357 - 6,378 km…
ilometers (13 mi) 
3. Work in groups. Group A is to make question forms, group B will
make negative forms, Group C will find the translation of the sentences 
below: 
1. Geodesists have developed a number of models to represent a closer
approximation to the shape of the Earth; 
2. The Earth deviates from a perfect sphere by only a third of a percent;
3. The Earth is only approximately spherical, so no single value serves as its
natural radius; 
4. Any radius falls between the polar minimum of about 6,357 km;
5. The difference distances correspond to the polar radius;
Work in groups. Write the main characteristics of the cartography 
types and show advantages and disadvantages:

Conclusion: 
Remember the dimensions of length and squares:
