According to the following graph, the coastline of Antarctica is receiving increased snowfall as well as ice melt over the past 10 years.

What would be the ​MOST LIKELY reason for this occurrence?

• Decreased surface temperature produces less ice, resulting in less snowfall in the region.

• Increased surface temperature evaporates more ice, resulting in less snowfall in the region.

• Decreased surface temperature produces more ice, resulting in more snowfall in the region.

• Increased surface temperature evaporates more ice, resulting in more snowfall in the region.

Karen is teaching her younger brother about interactions on Earth. She tells him that the geosphere and hydrosphere are in constant interaction. What evidence could she use to support her statement?

• Rain falls on the ground and runs along the surface of the ground, eroding soil and depositing it into a nearby lake bed.

• The Sun's energy evaporates water which rises as water vapor and condenses as clouds.

• Tree roots weather rock by breaking it into smaller pieces.

• Moist soil allows Earthworms to absorb oxygen through their skin.

Ptolemy believed that all objects in space, including the sun, revolved around Earth. Nicolaus Copernicus made observations showing that Earth and other planets revolved around the sun, which refuted Ptolemy’s argument. What is this an example of?

• Scientific knowledge is communicated between scientists.

• Scientific knowledge always stays the same.

• Scientific knowledge changes as a result of new evidence

Brandon noticed that hummingbirds in his yard visited all the flowers, but especially seemed to like the red trumpet-shaped ones. He read that they use the nectar in the flowers for food. He assumed that since the parents were eating nectar, they must feed their babies nectar as well. To his surprise, he saw hummingbirds bringing small insects and spiders to feed the young hummingbirds. How does this new evidence affect his original assumption?

• He should change his original assumption that they only feed their babies nectar.

• He should be able to stick to his assumption that the babies eat nectar since he thought that first.

• He should believe what he read in the book and disregard what he witnessed.

• He should ask other people what they think and agree with the majority.
