There are two coordinate system that the Philippines use. This coordinate system locate places in the Philippines to be more precise.
PTM
true or false
Soil Horizon O is the least weathered among the horizons because it is composed of the loose parent material.
false
Horizon C
Planet Earth receives visible light from the sun which is converted to heat. What process by which Earth’s atmosphere is heated?
greenhouse effect
Looking at the sky and clouds helps me tell the weather. These are low sheets or layers of which looks like "spread out" clouds or stretched in layers.
Stratus Clouds
What is the air that exerts pressure on Earth due to gravity?
Air Pressure
When locating places in the map, parallel lines are used to measure _____ or the Northings, which is the measure of distance from north to south of the equator.
latitude
In many areas, topsoil is being lost because of erosion. What happens to the soil?
The soil is carried off by water and wind.
The Earth is spinning on its axis called rotation. What do you call the apparent shift in the path of any object moving above the surface of the Earth due to Earth’s rotation? Instead of moving on a straight path the object gets deflected or take the curve path.
Coriolis Effect
Whenever I see shooting stars, it reminds me of this layer of atmosphere where meteors start to burn up before it reach the ground. It is also the coldest layer.
mesosphere
How does air pressure help us determine the weather?
high pressure - fair weather
low pressure - bring rain
Philippines is rich in natural resources but we are faced with many environmental problems because of many reasons and human activities. Name some environmental issues that we face.
air pollution, water pollution, deforestation, soil degradation, poor waste management
Soil is an example of nonrenewable resources because it takes longer time to be replaced. How does soil formed in nature?
formed when rocks break into smaller pieces
Wind is also called moving air moreover wind direction refers to the direction of the wind where it is going. True or False

thermosphere
Name the large bodies of water that surrounds the Philippines
West Philippine Sea

What are some of the effects of lead poisoning to humans?
headaches, dizziness, insomnia, stupor
Winds are caused by the different air pressures in the different places. True or False
What is the effect of rising global temperatures?
abnormal weather patterns
Explain air pressure as temperature changes.
Cold air sinks at high pressure areas while warm air rises at low pressure areas
Explain why the Philippines experiences rainy seasons
- location of the Philippines
- we are near the ITCZ (low pressure areas are formed)
- we are near the equator were two different air masses meet thus storms are formed
- we receives more solar radiation where there is unequal heating and cooling of air, land and seas
What must be done by quarrying and mining companies for mined-out areas in the Philippines based from the law?
Rehabilitate mined out areas
How many islands do we have in the Philippines?
7641
Explain what happens to solar radiation as it reaches the Earth's surface.
51% absorbed
19% absorbed by clouds and atmosphere
30% scattered and reflected from clouds and atmosphere
Explain the composition of air molecules at the sea level and at higher altitude.
The air molecules at the sea level are compact while air molecules at a higher altitude are widely spread due to less air.
