• Radio waves are a type of electromagnetic radiation with a much longer wavelength than visible light.
• Love waves produce entirely horizontal motion.
• Seismic Waves are the waves of energy caused by the sudden breaking of rock within the Earth.
• Surface Waves travel more slowly through Earth material at the planet's surface and are predominantly lower frequency than body waves.
• Conduction governs the thermal conditions in almost entire solid portions of the Earth.
• Transfer of heat from one object to another by direct contact is known as Convection and it dominates the thermal conditions in the zones where large quantities fluids (molten rocks) exist.
• Subduction is the process by which collisions of the Earth's crustal plates results in one plates being drawn down or overridden by another.
• Radiation is the transmission of heat into the surrounding space.
• Physical Weathering, also known as mechanical weathering or disintegration, causes rocks into small pieces with pieces retaining the characteristics of the original.
• Chemical Weathering occurs when the internal structure of mineral changed by the removal or addition of elements.
• Volcanism is a geological phenomenon that occurs on the surface of the earth.
• The motion of volcanism takes place inside cracks that infiltrate the upper mantle.
• Volcanism is a process correlated with the flow and transportation of igneous material towards the surface.
• Internal Heat from the molten rock on the mantle was transferred by convection and through conduction it will pass the crust to the surface of the Earth.
• Tornado Threat is a potential storm surge.
• Wildfire is an unplanned, unwanted fire burning in a natural area, such as a forest, grassland, or prairie.
• Magnitude measures the great size or extent of something.
• Landslide is a prolonged drought followed by heavy rainfall.
• Intensity measures the strength or effects brought by earthquake.
• Lahar follows a volcanic eruption, heavy rainfall triggers the rapid flow of mud and debris down the slopes of the volcano.
• PAG-ASA is the Philippine Atmospheric, Geophysical and Astronomical Services Administration.
• 47 Terrawatts is the approximate terawatts in the flow of heat in Earth’s interior to its surface.
• Weathering is the process of disintegration (physical) and decomposition (chemical) of rocks; breaking down of rocks into smaller particles.
• Erosion is the separation and removal of weathered rocks due to different agents (water, wind, or ice) that causes transportation of minerals to where they're deposited.
• Disintegration is a mechanical process that breaks large masses of rocks into small fragments.
• Decomposition is a chemical process which results in the formation of new substances such as from elements to rocks.
• Exfoliation is a process where rocks crack and flake off in layers due to pressure.
• Frost Wedging is a process where water gets inside the joints, causing alternate freezing and thawing episodes to pry the rock apart.
• Abrasion is the wearing away of rocks by constant collision of loose particles.
• Biological Activity refers to the changes in rocks due to plants and animals as agents of mechanical weathering.
• Dissolution is the process where rocks or minerals are dissolved by water.
• Hydrolysis is the process of breaking down rocks by acidic water to produce clay and soluble salts.
• Oxidation is the process of breaking down rocks by oxygen in/and water, often giving iron-rich rocks a rusty weathered surface.
• Mass wasting is the downslope movement of rocks and soil under the influence of gravity.
• Landslide is a mass of rocks or sediment sliding downslope along a surface.
• Rockslides are rapid flows of rock mass along a flat inclined surface.
• Slump is a phenomenon due to slow to moderate sliding of sediment or rock mass along a curved surface.
• Rock Fall and Debris Fall are the free falling of dislodged bodies of rocks or a mixture of rock, regolith, and soil.
• Mudflow is a very slow to rapid movement of fine-grained sediment and rock particles up to 30% water.
• Erosion is the process of the separation and removal of weathered rocks due to different agents (water, wind, or ice) that causes transportation of minerals to where they’re deposited.
