4th Quarter Earth and Life Science 7

• Earth,s hour per day until June is 23.5
• Oblate Spheroid - The shape of the Earth.
• Summer Solstice - called as the longest daytime
• Winter Solstice - called as the longest nightime
• Tropical Year - time it takes for the earth to complete one revolution around the sun
• Equinoxes - equal length of day and night starting from the month of June
• Solar Eclipse - occurs when the moon passes between the sun and the earth
• The moon revolves around the earth once every month or lunar cycle
• Lunar Eclipse - occurs when the earth passes between the sun and the moon
• Summer - at the northern Hemisphere every month of June.

  Winter - at the Southern Hemisphere every month of June.
• The Seasons change Every 3 months Summer - Autumn -Winter - Spring
• Seasonal Changes are caused by the tilted axis of the earth on its own axis, which causes different parts to receive more sunlight than others during certain times of the year.
• Summer - at the Southern Hemisphere every month of December.

  Winter - at the Northern Hemisphere.
• Eclipses

  1. Solar - (dark)
  2. Lunar - (light)
• Earth's rotation takes 1 day, while The Earth's Revolution from the sun takes 365.25 days, causing a leap year every 4 years.
• Inter Tropical Convergence Zone - A region of high pressure that extends from the equator to the tropics
• Tropical Countries - are called to the countries lived near the equator, they have a warm climate and mostly rainforest.
• Sand vs Land

  At Daytime, Sand absorbs heat fastest while at night Land loose heat fastest.
• Low Pressure Area - goes to the place where warm air rises
• High pressure area - the replacement of the air that the low pressure area has pushed out. (No rise of warm air)
• Typhoon - happens at the interaction of the rise or warm air (LPA) and the replacement of HPA
• Monsoon - wind system
• Sea to Land = Sea Breeze

  Land to Sea = Land Breeze

  (The movement of air)
• A Philippines is a example of the tropical Country that rises heat.

  The movement of air(wind) from North will move across the Pacific Ocean. It is called the Northeast Monsoon(amihan) happens every month of Dec.-Feb.

  The movement of air(wind) from

  South will move across the West Philippine Sea. It is called the Southwest monsoon(habagat) happens every month of July-Sept.
• Reasons Increasing CO² in Atmosphere

  • Factories
  • Burning of Garbage
  • Cutting Down of trees
  • Increase of Population
  • Smoke from Buses Trucks (invention from the Great Scientist "Albert Einstein") The E=mc². •Oceans, Lakes,seas
• What happens when air is heated? Answer: it rises, cause the molecules is lightweight
• What happens to the surrounding air as warm air rises?

  Answer : Japan - winter

  Philippines-summer(RISES)

  The Japan's air will moves towards the Place(Philippines) that rises. Bonus
• Thermosphere - 80-110 km, hot weather,

  This is where the space shuttle is found (signal/Bantay)
• Aurora

  2 kinds of Light

  • North - Borcalis
  • South - Australis
• Exosphere - 500-1000km above the Earth's surface
• Temperature - division of layers in Atmosphere variations
• Global Warming - increasing of certain gases.
• The greenhouse gases on the Atmosphere is 1 percent and the Carbon Dioxide/part of green house contain 0.3
• Greenhouse:

  • less fertilizer
  • Less insect
  • Less wind
  • Trap the heat
• On the Earth's surface the transparent layer will get surpassed by the heat/UV rays of the Sun falling all the way to the land "Plants" And will bounce back to the Atmosphere but the CO² will stop the bounce of the heat right where the Mesosphere.
• Renewable - can be replaced in short period of time
• Non Renewable - can't be replaced in short period of time
• Which of the following materials deposits is the hardest? Silver,Diamond or Bronze

  Answer: Diamond is the hardest material because it has a unique atomic structure that makes its carbon atoms exceptionally resistant to scratching or deformation. This property gives diamond its renowned durability and makes it ideal for various industrial applications, including cutting, drilling, and polishing.
• Hydrosphere - liquid portion of the Earth
• Lithosphere - Solid portion of the Earth
