1. What are the primary layers of the Earth and their characteristics?
Answer: The Earth has three primary layers:
● Crust: The outermost layer, which is solid and includes both continental and oceanic
crust. It is relatively thin compared to the other layers.
● Mantle: Located beneath the crust, the mantle is semi-solid and convective. It is
responsible for tectonic plate movements and volcanic activity.
● Core: The innermost layer, composed of a liquid outer core and a solid inner core. The
core is primarily made of iron and nickel and is responsible for the Earth's magnetic field.
2. Explain the difference between weather and climate.
Answer:
● Weather: Refers to the short-term atmospheric conditions in a specific place at a
specific time, including temperature, humidity, precipitation, and wind.
● Climate: Represents the long-term average of weather patterns over an extended
period (typically 30 years) in a specific region.
3. What are the main factors that influence climate?
