1 Where On Earth Is The Philippines?

What I Need to Know

This module was designed to simplify the concepts of demonstrating how

places on earth may be located using a coordinate system (S7ES-Iva-1).

It’s time to talk now about the location of our country, the Philippines.

Where is the Philippines? You may answer, the Philippines is on earth, of course, but where exactly is it located? In this module, you have to learn a new

skill: finding places using latitude and longitude using a map or globe. After

going through this module, you are expected to:

1. Demonstrate how places on earth may be located using a coordinate

system;

2. Identify the location of the Philippines using latitude and longitude; and

3. Determine the location of the Philippines relative to the surrounding landmasses and bodies of water;

Searching for places using a map or a globe could be time-consuming,

and worst, you don't even know where to start. When you invite a friend to your

house, they could locate your residence when you give them your address. You

can find a place quickly if you know the address, and all places on earth have their specific address.

What is it Study the image of a globe below. After studying the image on the right, try to

define "equator" in your own words.

The "northern hemisphere" is that part of the world between the North Pole and

the equator is called the "northern hemisphere". The "southern hemisphere" is situated

below the equator. (Science LM 7)

Look closer at the lines of latitude.

Q1. Describe the lines of latitude. (2 pts)

Q2. What is the starting point of latitude? ____________ (1pt)

The equator is at latitude 00 (zero degrees). At the North Pole, the latitude is

900 N, and at the South Pole, the latitude is 900S (90 degrees south)

The starting point of the longitude is the Prime Meridian passes through Greenwich, England. To the Prime Meridian's right, the longitude is written this way:

150E (15 degrees east), 300W, and so on. To the left of the Prime Meridian, the

longitude is written as 150 west (15 degrees west), and so on. (Science LM 7).

Q3. Using your map, what is the latitude and longitude of Manila?

________________(2pts)

Now that you know how to describe the location of a particular place using

latitude and longitude. The lines of latitude are parallel to the equator and each other,

that is why it is called parallels of latitude. Five lines of latitude have unique names.

The table below shows the names of each . The latitude values have been rounded

off to the nearest half-degree. (Science LM 7)

Get a globe or world map and find the Tropic of Cancer and the Tropic of

Capricorn. The part of the map between the two is called the tropics, and the

Philippines is part of this region.

Now, look for the Arctic Circle and the Antarctic Circle on the globe or map.

Between the Tropic of Cancer down to the Arctic Circle is the northern temperate zone; while places between the Tropic of Capricorn to that in the Antarctic Circle is the

southern temperate zone. Places or Countries in these zones go through the four

seasons-winter, spring, summer, and autumn.

Finally, the Arctic Circle and Antarctic Circle areas are called the polar regions

or frigid zones.

To sum up, the closer the latitude of the place to the equator, the warmer the

climate of that region or place. The closer it's latitude to the poles, the colder the place

or region. Thus, there is a relationship between the latitude of a place and the climate

it experiences. (Science LM 7)
