The minerals in a rock react with oxygen in the air. When this happens, the rock starts to break down, creating large holes in its surface. What is this an example of? (1 point)
• Weathering
• Erosion
• Deposition
• Gravity
The correct answer is weathering.
The correct answer is: Illustrations with lines that go in loops with the smallest loops representing the highest points in the region.
The correct answer is: Weathering breaks down rock, erosion moves rocks, and deposition places rocks in a new location.
Which of the following best described topographical maps? (1 point)
• Drawings that have exactly replicated images of the earth's features like mountains, rivers, and canyons.
• Images taken from space that show the earth's features like mountains, rivers and canyons.
• Illustrations with lines that go in loops with the smallest loops representing the highest points in the region.
• Videos taken from space that show how rivers flood and how that impacts the environment in the area.
How do weathering, erosion, and deposition work together to change earth's surface? (1 point)
• Erosion breaks down rock, weathering moves rocks, and deposition places rocks in a new location.
• Weathering breaks down rock, erosion moves rocks, and deposition. places rocks in a new location.
• Deposition breaks down rock, erosion moves rocks, and weathering places rocks in a new location.
• Weathering breaks down rock, deposition moves rocks, and erosion places rocks in a new location.
Over a period of a hundred years, how could it be determined how the shape of a structure on earth has changed using topographical maps? (1 point)
• The original map would become larger so that more detailed structures could be observed.
• Comparing the two images taken from space of the structure would be how the differences are identified.
• The shape of the loops on the map would be changed to imitate the new shape of the structure.
• The changes will not be able to be determined through topographical maps because the loops will remain the same.
