Grade 10 Science Examination questions are designed to assess students' understanding of key scientific concepts and their ability to apply knowledge to real-life situations. These questions typically cover topics such as biology, chemistry, physics, and environmental science. They require students to demonstrate critical thinking, problem-solving, and analytical skills. Some questions may involve interpreting diagrams, analyzing experiments, or explaining natural processes like weather patterns or energy transfer. Past examination papers, such as the 2015 Grade 10 Science paper in Papua New Guinea, serve as valuable resources for students to practice and familiarize themselves with the question format. Reviewing these questions helps students build confidence and improve their performance in the final examination.
Solution
Observe the Diagram: The diagram shows air movement during the night, indicated by the moon and the labels "Night" and "Cool air coming off land."
Identify Temperature Differences: The land is labeled as "Cool land," while the sea is labeled as "Warm sea." This indicates that at night, land cools down faster than water.
Analyze Air Movement: Cool air from the land moves toward the sea, and warm air over the sea rises. This movement suggests that air is flowing from the land to the sea.
Understand the Concept: This type of air movement is characteristic of a land breeze, which typically occurs at night when the land cools faster than the sea, causing cooler air to move from the land to the warmer sea.
Choose the Correct Answer: Based on the description and understanding of the breeze, the correct answer is : A. land breeze.
