To calculate or estimate distances we may need tools like ____________ and ______________.

To calculate distances with a Numerical Scale

1) Use a ruler to measure the distance between the two points on the map

2) Convert the centimeters you measured to kilometers.

In a numerical scale you convert centimeters to kilometers by

1) Multiply the # of centimeters by the # in the scale

2) Divide by 10 (the number of centimeters in a km)

The imaginary circles on the surface of the earth paralleling the Equator and marking the latitude are called:

The semicircles that run from north to south and meet at the Poles are called:

______________ is the distance measured in degrees starting at 0º on the Equator. It divides the Earth in North (N) or South (S).

______________ is the distance measured in degrees from the 0º meridian in Greenwich to its anti-meridian. It divides the Earth in East (E) or West (W).

______________ is the vertical distance of a point on the Earth’s surface from sea level.

What are the coordinates of the impostor?

What are the coordinates of the impostor?

The _______________________ became the reference point for adding hours or subtracting hours depending on the number of time zones crossed.

The 180º meridian is also called the _______________________________ . This is where the date changes when we cross from one hemisphere to another.

How many time zones does Mexico have?

Sonora doesn´t change time. This is because it has important economic links with the state of Arizona, in the United States.

What map projection is this one?

What map projection is this one?

What map projection is this one?

Which projection shows all of the Earth’s surface while simulating the shape of the globe? It is commonly used in teaching.

Which projection is most frequently used for making maps for navigation? This is because the perpendicular lines of the parallels and meridians make it easy to plan a route on the map.

Which projection is useful because it allows us to compare the sizes of different countries, because the real surface areas of continents maintain their proportions?
