Natural resources

Front 10

Natural resources that are potentially useful as a source of water supply

Back 10

Water resources

Front 11

Are a form of environmental asset providing a range of ecosystem services. A key feature of this resource is their delivery of supporting services including the formation of and function of the soil, nutrient cycling, water cycling, structural support of vegetation and soil biodiversity

Back 11

Soil resources

Front 12

Is a significant factor not only in soil formation but also in sustaining diversity of plants and animals

Back 12

Climate

Front 13

Something that can produce heat, power life, move objects, or produce electricity.

Back 13

Energy Resources

Front 14

is a renewable energy source because heat is continuously produced inside the earth

Natural gas

Front 17

made from decomposing plants and animals. Found in the Earth’s crust and contain carbon and hydrogen, which can be burned for energy

Back 17

Fossil fuel

Front 18

It is the layer of air that extends to about 50 km form Earth’s surface. Many jet aircraft fly because it is very stable

Atmosphere

Front 21

It is the layer between 50 km and 80 km about the Earth’s surface, the air in this layer is very thin and cold

Back 21

Mesosphere

Front 22

It is between 80 km and 110 km above the Earth. Space shuttles fly in this area and it is also where the auroras found

Front 23

It is the upper limit of atmosphere. This layer of the atmosphere merges into space, Satellites are stationed in this area 500 km to 1000 km from Earth

Back 23

Exosphere

Front 24

It is the process by which the Earth’s atmosphere warms up

Back 24

Greenhouse effect

Front 25

It is naturally produced when people and animals breathe

Back 25

Carbon dioxide

Front 26

Comes from grazing animals as they digest their food and from decaying matter in wet rice fields

Back 26

Methane

Front 27

Are wind systems, usually bring abundant rainfall, also called amihan or habagat

Back 27

Monsoons

Front 28

The wind blows from the high-pressure area in the Asian continent toward the low-pressure area south of the Philippines

Back 28

Amihan

Front 29

The wind will move from the high-pressure to the low-pressure area in the Asian continent. This monsoon wind is locally called

Back 29

Habagat

Front 30

Is also naturally present in the stratosphere

Back 30

Ozone

Front 31

Occurs in the troposphere because this layer contains most of the water vapor

Back 31

Weather

Front 32

Warm air rises, and air moves toward the place where warm air is rising

Front 37

It is the half of the Earth that is north of the equator

Back 37

Northern hemisphere

Front 38

It is the half of Earth that is south of the equator
