Science 7

• Coordinate System - in trying to locate a particular text in a book.
• Horizontal lines and Vertical lines - earth is divided into
• Horizontal reference point - starting at the plumpest part of earth is the equator
• Equator - corresponds to 0⁰,the pointof reference where all other horizontal lines are measured from
• Latitudes - these lines that divide earth horizontally
• 23.5⁰N - Tropic of Cancer located
• 23.5⁰N - Tropic of Capricon located
• 66.5⁰N - Arctic Circle located
• 66.5⁰S - Antarctic Circle located
• Longitudes(Meridians) - vertical lines are called,which divide earth into wedges
• North and South Poles - lines of longitudes pass over,and are contained in a plane that pass through the center of earth.
• Prime meridian - where longitudes start,and corresponds to 0⁰ and divide earth into east and west
• Greenwich meridian - the prime meridian is also called (?) because it passes through Greenwich,England
• Antimeridian - the line opposite the prime meridian,which coincides with 180⁰,sometimes called
• Relative location - it is a location that uses a choosen reference that will serve as the basis for its location,coming from the west and coming from the southwest
• Vicinal location - the area being described is within the vicinity of one landmark or another known location
• Absolute location - location that does not change no matter what happens to the surroundings
• International community - agreed on using the longitudes and latitudes
• Insular location - specific way of locating an island,location based on the bodies of water surrounding it
• Early map makers - made it easier for us to locate the places by setting up a system that everyone can use
• Philippines - described as an archipelago found in Southeast Asia
• Archipelago - is a place surrounded by bodies of water in all directions
• Sustainability - this means maximizing the use of resources to have a good life while ensuring that future generations would still enjoy these resources
• Fiber optics - this is needed to make asphalt and concrete roads strong and durable
• Bitumen - this binds the petroleum products in asphalt
• Microplastic - it just ends up as pollution when we wash our clothes
• Water footprint - this measure of the amount of water needed to produce a product
• DENR - according to them there are some places in the Philippines where mineral resources of economic value can be seen
• They are Renewable/Nonrenewable

  fishes,trees,soil,water and coal
• Renewable- are the materials that can be replaced or replenished over a reasonable span of time,especially when managed properly
• Nonrenewable - are those that cannot be replaced or replenished over a reasonable amount of time
• Manage sustainably - renewable can also become a nonrenewable if it is not
• Example of renewable

  soil,sun,geothermal energy and the wind
• Renewable that can become nonrenewable if not managed properly

  trees,plants,water and fishes
• Fossil fuels and petroleum - products come from deep inside earth
• Petroleum - is made mostly from the tiniest of organism such as ancient zooplankton and microscopic algae
• Natural gas,crude oil or petroleum and coal - three forms of fossil fuels
