Lesson 1.5 Movement of Earth

1. Rion – earth movement around its ax in counter-clockwise direction, takes hours
2. Retion – movement of the earth around the sun, in counter-clockwise direction, takes ¼ days

* Rotation Effects
1. day and nt
2. te difference in various places – 24 different time zs, 1 degrees longitude per time zone, time in eern hemisphere is always ahead

* Air Temperature
1. Breeze – during day time, cool air over the water moves to the warm air in the land
2. d Breeze – during night time, cool air over the land moves to the warm air over the water

Lesson 1.5 Movement of the Earth

Revolution
• Ot – earth’s path around the sun
• 2.5 degrees – earth’s tilt from its orbit

* 4 seasons
1. Sr – June, ds are longer than nights in northern hemisphere
2. An – September, day and night are equal length
3. Wr – December, nts are longer than days in northern hemisphere
4. Sg – March, nights are day are equal length

Cle – atmosphere condition over a long period of time

* Climate Factors
1. Sun’s rs angle
2. Large bodies of wer presence
3. Location surce difference

* Climate groups
1. Trcal climate zone – near equator, warm climate
2. Por climate zone – near the poles, cold climate

Lesson 1.6: Philippines Location and Climate

• Philippines – an arlago with 7,7 islands, located in Sthst Asia, with total land area of 30,000 square kilometers, and has a Tral Climate.
• Vial Location – helps find a place base on neighboring countries
• Maime or Insular Location – helps find a place base on different water forms surrounding it

Philippine Neighbors:
1. Bri
2. Malia
3. Indsia
4. Singre
5. Viem
6. Thand
7. Myar
8. Cadia

Philippine Waters:
1. South Cna Sea – north & west
2. Pfic Ocean – east
3. Cees & Su Sea – south

Philippine Boundaries:
1. Y’i – northernmost island
2. Salg – southernmost island
3. Balac Island – farthest point in the west
4. Pun point – farthest in the east

• Tyon Bt – where the Philippines is located, the reason why it experiences at least 2 typhoons every year
• Trcal Cyes – low pressure areas in the tropics, usually occurs in the Pfic Ocean.
• E of the Sm – center of the typhoon

• Mon – seasonal wind flow between northern and southern hemisphere

Factors affecting Philippine Climate:
1. Loion
2. Wd System
3. Arpelagic Nature
4. Tography

Philippine Seasons:
1. – May to October
2. – November to April

Monsoons:
1. Northt monsoon
2. Southt monsoon – or Hat

Air Movement:
1. Breeze – sea to land, at daytime, cooler air from the sea moves to the land
2. d Breeze – land to sea, at night time, land air cools far than water and moves to the sea.

Lesson 1.6: Philippine Climate

• PAA – government agency that gives warning when a typhoon is coming
• Dotic Bulletin –warnings issued by PAGASA

Tropical Cyclones Classification:
1. Tropical Disnce – poorly developed wind
2. Tropical Desion – weak low pressure
3. Tropical Stm – moderate tropical cyclone
4. Tyon – storm that brings heavy rains, hits places with destructive forces

Storm Signals (Wind speed)
1. Signal No. 1: 30 – 0 kph
2. Signal No. 2: 60 – 00 kph
3. Signal No. 3: 100 – kph 15
4. Signal No. 4: > 185 kph
