• weather - a condition of the atmosphere in a specific place and time
• weather pattern - occurs when the weather stays the same for days or weeks at a time.
• Hanging Amihan - Also called as northeast monsoon, is responsible for cold and dry weather patterns in the country.
• Hanging Habagat - also known as southwest monsoon, is responsible for wet and rainy weather patterns in the Philippines and is characterized by a strong, generally west or southwest breeze that is warm and humid, which is coming from the Indian Ocean.
• trade winds - bring rain to only the eastern part of the country.
• Seasons - determined by Earth's revolution around the sun and its inclination on its axis.
• Regions that are tilted toward the sun experience warmer temperature and longer daylight.
• Regions that are tilted away from the sun experience cooler temperatures and shorter daylight.
• Winter : December Equinox to March Equinox
• Fall : September Solstice to December Equinox
• Summer : June Solstice to September Solstice
• Spring : March Equinox to June Solstice
• Autumn : September Equinox to December Equinox
• Summer: June Solstice to September Equinox
• El Nino - a natural phenomenon that occurs every 2-7 years and is caused by the warming of the ocean surface.
• La Nina - characterized by cold ocean temperatures, and heavy rains.
• Tropical Depression - develops when a tropical cyclone, a low pressure area has a speed of 62 kilometers per hour or less.
• Typhoon/Hurricane - develops when a tropical depression reaches wind speeds of more than 185 km/h.
• PAGASA - Philippine Atmospheric, Geophysical and Astronomical Services
• NDRRMC - National Disaster Risk Reduction and Management Council
• Heliocentric - the model of the solar system being used today.
• Nicolaus Copernicus - a Polish astronomer considered as the father of modern Astronomy
• In 1600s, Nicolaus Copernicus proposed that the planets revolve around the sun.
• Heliocentric - also known as Sun-centered astronomy and Copernican model is the model of the Solar system being used today.
• Orbit - an imaginary path around the sun.
• Rotation - Earth spins on its tilted axis.
• Axis - an imaginary line that is tilted 23.5 degrees and runs through the center of the Earth.
• Earth rotates in a counterclockwise direction.
• Earth's revolution - the orbital motion it completes around the Sun, taking approximately 365.25 days to complete one full orbit.
• Perihelion - Earth is at its closest point to the sun with a distance of 147.1 kilometers between them.
• Aphelion - Earth is farthest from the sun with a distance of 152.1 million kilometers between them.
• Spring - characterized by warm weather and flowers in bloom.
• Summer- the hottest time of the year.
• Autumn - marks the time when leaves of trees begin to fall as the weather gets colder.
• Winter - the coldest season characterized by ice and snow
• Universe - the totality of all is in the outer space.
• Nebula -also known as star nurseries and a cloud of dust and gas where stars begin to form.
• Stars form from the gravitational collapse of massive clouds of gas and dust, leading to nuclear fusion at their cores, where hydrogen atoms combine to form helium, releasing vast amounts of energy in the process.
• Types of Nebula

  • Emission Nebula
• Nebulas

  • Emission Nebula
  • Reflection Nebula
  • Dark Nebula
