Science chapter 12 class 8 solution : Some natural phenomenon

Natural phenomena are events or processes that occur in the physical world as a result of natural forces and without direct human intervention. Here are some examples of natural phenomena:

Lightning: The sudden discharge of electrical energy in the atmosphere, creating a visible flash of light and a thunderclap due to the rapid heating and expansion of air.

Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights): Luminous natural light displays in the Earth’s sky, primarily in polar regions, caused by the interaction of solar wind particles with the Earth’s magnetic field.

Tornadoes: Violently rotating columns of air extending from thunderstorms to the ground, capable of causing widespread destruction.

Earthquakes: The sudden release of energy in the Earth’s crust, resulting in ground shaking and the potential for significant damage and geological changes.

Volcanic Eruptions: The expulsion of molten rock, ash, and gases from a volcano due to pressure build-up beneath the Earth’s surface.

Tsunamis: Large ocean waves generated by undersea earthquakes, volcanic eruptions, or landslides, which can cause massive destruction when they reach coastal areas.

Solar and Lunar Eclipses: Occur when the Earth, the Moon, and the Sun align in a way that one celestial body is obscured by the other, causing temporary changes in light or visibility.

Rainbows: Optical and meteorological phenomena that result from the refraction, dispersion, and reflection of sunlight in water droplets in the atmosphere.

Seasons: The cyclic changes in weather and temperature that occur due to the Earth’s axial tilt, causing variations in the length of daylight and the angle of sunlight throughout the year.

Geysers: Hot springs that intermittently eject columns of hot water and steam into the air due to underground pressure and heating.

Meteor Showers: Periodic events where a large number of meteors (shooting stars) become visible in the night sky as the Earth passes through the debris left by a comet.

Glaciers: Large masses of ice that move slowly over land, shaping landscapes through the process of glaciation.

Hailstorms: Severe weather events where large, often destructive, hailstones form due to strong updrafts in thunderstorms.

Ocean Currents: Large-scale flows of water in the world’s oceans, driven by various factors, including wind, temperature, and salinity differences.

Super moon: A full moon that appears larger and brighter in the sky due to its closer proximity to Earth in its elliptical orbit.

Science chapter 12 class 8 solution – Important definition

Floods:

Floods are natural disasters characterized by the overflow of water onto normally dry land, often caused by heavy rain, snow melt, or the breach of water bodies like rivers.

Science chapter 12 class 8 solution- Pandemic:

A pandemic is an outbreak of a disease that occurs on a global scale, affecting a large number of people across multiple countries or continents.

Science chapter 12 class 8 solution- Evaporation:

Evaporation is the process by which a liquid, such as water, changes into a vapor or gas state when exposed to heat or ambient temperatures.

Science chapter 12 class 8 solution- Hurricane:

A hurricane is a powerful and destructive tropical cyclone characterized by strong winds, heavy rainfall, and a well-defined eye at its center.

Science chapter 12 class 8 solution- Lightning:

Lightning is a sudden and powerful electrical discharge in the atmosphere, often accompanied by a flash of light and thunder.

Science chapter 12 class 8 solution- Earthquake:

An earthquake is a sudden release of energy in the Earth’s crust, resulting in ground shaking and seismic waves due to the movement of tectonic plates.

Science chapter 12 class 8 solution- Landslides:

Landslides are the downward movement of rock, soil, or debris on a slope or hillside, often triggered by factors like heavy rainfall or earthquakes.

Science chapter 12 class 8 solution- COVID-19:

COVID-19 is a highly contagious respiratory illness caused by the SARS-CoV-2 virus, leading to a global pandemic in 2019-2020.

  • Science chapter 12 class 8 solution

    Storm:

A storm is a violent atmospheric disturbance characterized by strong winds, heavy precipitation, and various meteorological phenomena, such as thunderstorms and blizzards.

Seismograph:

A seismograph is an instrument used to detect and record ground motion and seismic waves caused by earthquakes or other sources of vibration.

Epidemic:

An epidemic is a sudden and widespread outbreak of a disease in a specific geographic region or population, exceeding what is normally expected.

Cyclone:

A cyclone is a generic term for a low-pressure system in the atmosphere, known by different names in various regions, such as hurricanes and typhoons.

Typhoon:

A typhoon is a term for a tropical cyclone that occurs in the northwestern Pacific Ocean, similar to a hurricane.

Epicenter:

The epicenter is the point on the Earth’s surface directly above the origin of an earthquake’s seismic activity.

Richter Scale:

The Richter scale is a logarithmic scale used to measure the magnitude of earthquakes, quantifying the energy released during seismic events.

Electroscope:

An electroscope is a scientific instrument used to detect and measure the presence and magnitude of electric charges by their effect on the movement of a metal or foil leaves.
