1. The asthenosphere is part of the Earth’s mantle and lies just below the lithosphere.
2. The asthenosphere is solid and does not flow, allowing the tectonic plates to remain static.CorrectAnswer: A. 1 only
Explanation:
• Statement 1: Correct. The asthenosphere is a layer of the Earth’s mantle located beneath the lithosphere and above the mesosphere.
• Statement 2: Incorrect. The asthenosphere is highly viscous and flows plastically under high temperature and pressure. This flow enables tectonic plates to move.IncorrectAnswer: A. 1 only
Explanation:
• Statement 1: Correct. The asthenosphere is a layer of the Earth’s mantle located beneath the lithosphere and above the mesosphere.
• Statement 2: Incorrect. The asthenosphere is highly viscous and flows plastically under high temperature and pressure. This flow enables tectonic plates to move. - Question 5 of 5
5. Question
Consider the following statements about warm fronts:
1. A warm front forms when a warm air mass overtakes and rises over a cold air mass.
2. When warm, less dense air moves over the colder, denser air, the atmosphere is relatively stable.CorrectAnswer: C. Both 1 and 2
Explanation:
• Statement 1: Correct. Warm fronts occur when a warm air mass overtakes a cold air mass, causing the warm air to rise above the colder, denser air.
• Statement 2: Correct. The movement of warm, less dense air over colder, denser air typically creates a stable atmosphere, leading to prolonged, steady precipitation and relatively calm weather.IncorrectAnswer: C. Both 1 and 2
Explanation:
• Statement 1: Correct. Warm fronts occur when a warm air mass overtakes a cold air mass, causing the warm air to rise above the colder, denser air.
• Statement 2: Correct. The movement of warm, less dense air over colder, denser air typically creates a stable atmosphere, leading to prolonged, steady precipitation and relatively calm weather.
