• Coordinate System

  • An arrangement of reference lines or imaginary lines of a globe or map
• Reference line

  • divides Northern and Southern Hemisphere. Also divides the Eastern and Western Hemisphere
• Latitude

  • Horizontal
  • The latitude divides the Globe into Northern and Southern
  • The one who divide is Equator, and its starting point is 0 degrees
• Longitude

  • Vertical
  • The longitude divides the globe into Eastern and Western
  • The one who divide is Prime meridian, and its starting point is 0 degrees
• Special Lines

  • Equator
  • Tropic of Cancer
  • Tropic of Capricorn
  • Arctic Circle
  • Antarctic Circle
• Natural Resources

  • are materials or substance that occur in nature and can be used for economics gain. They are typically classified into renewable and non-renewable resources
• Renewable Resource

  • can be replenished naturally over time or can be replenished in a short period of time
• Non-renewable resources

  • cannot be replenished or it takes time to replenished and minerals are finite
• Natural resources can be destroyed through various human activities

  • Deforestation
  • Mining
  • Pollution
  • Overfishing
  • Climate change
  • Natural Disasters
• Conserve Natural Resources

  • Rethink
  • Recycle
  • Repair
  • Reduce
  • Refuse
• Flora

  • plants
• Fauna

  • animals
• Petroleum

  • is used to make plastic
• Tilapia

  • also known as St. Peter's Fish
• Soil

  • is a vital role
• Troposphere

  • clouds are form here, commercial planes can fly, all living things fly here like bird, weather occurs here and a lot of water vapor
• Stratosphere

  • Some planes fly here like Jet planes and plane will experience a turbulence, Cloud less / cloud free, Ozone layer is located here.
• Mesosphere

  • Coldest layer, meteors are burned down here
• Thermosphere

  • Hottest layer, northern lights happen here, and auroras
• Exosphere

  • Hot layer but not hot as thermosphere, satellites are found here, and spaceship, molecules from the sun are ionized
• The atmosphere is divided into:

  • Pressure/altitude
  • Temperature
• Breeze

  • Localized winds near bodies of water, called as a calm, light and gentle wind
• Sea Breeze

  • forms during the day, when land warms up faster than the sea, causing warm air to rise and cooler air from the sea to move towards the land. The air from land will grab moisture from the water so that the warm air will be turn into cool sea breeze
• Land Breeze

  • forms during the night, when land cools faster that the sea, causing warm air form the sea to rise and cooler air from the land to move towards the sea
• Northeast Monsoon

  • it brings wind that are dry and cool wind and have a slight to moderate rainfall. occurs during the month of November to Late April
• Southwest monsoon

  • it brings warm and moist wind and have a moderate to heavy, and torrential rainfall. it occur during month of June to October
• Intertropical Convergence Zone (ITCZ)

  • is where the trade winds from the Northern and Southern hemisphere meet at the equator or near the equator. Also known as the breeding ground for low-pressure areas where many disturbance forms
• Rotation

  • to its own axis, with 24 hours
• Revolution

  • The earth's orbit around the sun and make up to 365 and one fourth days to complete
• Perihelion

  • the earth is closer to the sun , so greater energy will receive
• Aphelion

  • the earth is far away to the sun , so lesser energy will receive
• Umbra

  • The dark inner portion of the shadow cone
• Penumbral

  • The lighter outer portion of the shadow
• Lunar Eclipse

  • when the earth casts a shadow on the moon causing the moon to go dark
• Solar eclipse

  • When the moon casts a shadow on the earth, causing the sun to go dark
• 23.5

  • Measurement of the Earth's tilt
• Axis

  • where Earth's rotation
• Equinox

  • Northern and Southern Hemisphere will receive equal amount of sunlight
• Eclipse

  • occurs an time something passes in front of the Sun blocking its light
• Solstice

  • These are the days when the Sun's path in the sky is the farthest north or south from the Equator. A hemisphere's winter solstice is the shortest day of the year and its summer solstice the year's longest.
