Science q1

• How many volcanoes are in the Philippines? - 24 volcanoes
• Theory that the earth's lithosphere is composed of mosaic of rigid plates that are relative in motion - Plate Tectonics
• Biosphere - part of earth wherein can find living and non-living this
• Geosphere - solid part of the earth
• Biogeochemical Cycle - a pathway by which a chemical substance moves through biotic-biosphere, ambiotic
• Earthquake - sudden and violent shaking of the ground, sometimes causing great destruction as a result of the movement within earth's crust
• Plate Boundaries- when the two plates are sliding past each other in opposite direction one plate is moving faster than another plate next to it
• Parts of the earth - crust, mantle, core
• Crust - outermost shell of the earth
• 2 different of crust - oceanic and thick continental crust
• Oceanic Basalt - dark gray to black dense
• Igneous Continental - Granite - very hard natural igneous rock formation of visibly crystalline l, texture use for building monamentum
• The oceanic crust is denser than continental crust
• Mohorovicic Discontinuity - the boundary between Earth's crust and mantle
• Mantle - largest part of the eart
• Earth's Mantle - olivine-rich rock
• Geothermal Gradient - responsible for different rock behaviours
• Molten - not melted
• Core Earth - iron and nickel alloy
• 2 different core - Inner Core and Outer Core
• Inner Core - is solid even though it's temperature is higher than the outer core
• Inner CORE - primarily Fe with some Nickel (-5%) and additional elements
• Outer Core - consists mainly of iron with significant amounts of another elements
• Location of Pacific Ring of Fire - Philippines
• Outside of Pacific Ring Of Fire - Australia
• Top 1 most earthquake country - Indonesia
• Circum Pacific Belt - other term for Pacific Ring of Fire
• Plate Boundaries - wherein two tectonic plates meet
• Mountain Rage - hill range is a series of girls arranged in a line and connected by high ground
• Rift Valley - a lowland region that forms where earths tectonic plates move apart
• Deep Sea Trench - called as oceanic track
• Deep Sea Trench - a long narrow depression on the seafloor
• Island Curve - long chains of active volcanoes with intense seismic activity found along convergent tectonic plates boundaries
• Fold Mountain - most common type of mountain, belong in type of mountain
• Mountains of Fold Mountains - Andes, Himalayas, Alps
• Asthenosphere - beneath the lithosphere, silly putty, part of upper mantle located before the crust of the earth, lies below the lithosphere
• Divergent-Convergent - two plates are moving towards each other
• Subductive - the other plate will go underneath if it already subduct it will form mountain
• Destructive - has earthquake two tectonic plates moves to each other
• Examples of Destructive - South American, Naza Plate
