3. Disasters: These are catastrophic events caused by natural processes of the Earth, such as earthquakes, hurricanes, floods, tornadoes, and volcanic eruptions.
4. Fronts are boundaries between air masses with different temperature and humidity characteristics, often leading to weather changes.
7. Gravity is the force that attracts objects with mass toward each other. It's what keeps planets in orbit around the sun and holds everything on Earth's surface.
11. (Cirrus, Stratus, Cumulus, Cirrostratus): These are different types of clouds with distinct characteristics. Cirrus clouds are wispy and high, stratus clouds are layered and cover the sky, cumulus clouds are fluffy and white, and cirrostratus clouds form high, thin layers.
12. Phases: The moon goes through different phases as it orbits the Earth. The main phases include waxing (increasing illumination), waning (decreasing illumination), gibbous (more than half illuminated), full moon (fully illuminated), quarter moon (half illuminated), and half moon (either waxing or waning).
13. Cycle: The water cycle is the continuous process of water evaporating from the Earth's surface, forming clouds, precipitating as rain or snow, and then flowing back to the surface through runoff or infiltration.
14. Tides are the periodic rising and falling of the Earth's oceans and are primarily influenced by the gravitational pull of the moon and the sun.

1. Seasons are caused by the tilt of Earth's axis. As the Earth orbits the sun, different parts of the planet receive varying amounts of sunlight, leading to changes in temperature and weather conditions.
2. The equator is an imaginary line around the Earth's middle, equidistant from the North and South Poles. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
5. Pressure: High-pressure systems are associated with descending air, leading to fair weather and generally clear skies.
6. Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbit around the sun. This tilt is responsible for the changing seasons.
8. Earth's axis is an imaginary line that runs from the North Pole to the South Pole, around which the planet rotates.
9. Pressure: Low-pressure systems are associated with rising air, leading to cloud formation and often precipitation.
10. Temperature is a measure of the average kinetic energy of molecules in a substance. It plays a crucial role in weather patterns and climate.
11. Climate refers to the long-term patterns of temperature, humidity, wind, and precipitation in an area.
