Question 1:
Which of the following is the primary source of energy for most weather on Earth?
Explanation: Solar radiation from the Sun is the primary source of energy for most weather on Earth. The Sun's energy heats the Earth's surface, creating temperature differences that drive atmospheric circulation and weather patterns. Therefore, the correct answer is A) Solar radiation.
Question 2:
Which of the following is NOT a type of severe weather?
Explanation: While fog can reduce visibility and cause travel disruptions, it is not considered a type of severe weather. Severe weather refers to conditions that pose a threat to life and property, such as tornadoes, hurricanes, and blizzards. Therefore, the correct answer is D) Fog.
Question 3:
What is the term for the boundary between two air masses with different temperature and humidity characteristics?
Explanation: The term for the boundary between two air masses with different temperature and humidity characteristics is a front. Fronts are important features in weather systems, often associated with the formation of clouds, precipitation, and changes in weather conditions. Therefore, the correct answer is A) Front.
Question 4:
What type of cloud is often associated with thunderstorms?
Explanation: Cumulus clouds are often associated with thunderstorms. These clouds have a tall and towering appearance, with a flat base and a rounded top. They are formed by strong updrafts of warm, moist air, which can lead to the development of thunderstorms and other convective weather phenomena. Therefore, the correct answer is A) Cumulus.
Question 5:
What is the term for a large-scale weather pattern that influences the long-term climate of a region?
Explanation: El Niño is a large-scale weather pattern that influences the long-term climate of a region. It occurs when warm ocean waters in the eastern Pacific Ocean affect global weather patterns. El Niño events can lead to changes in precipitation patterns, sea surface temperatures, and atmospheric circulation, affecting weather and climate conditions around the world. Therefore, the correct answer is B) El Niño.
