Water is less dense as a solid than as a liquid the answer is D
The KT boundary marks a mass extinction event. the KT boundary is the time between the Cretaceous and Tertiary periods. An asteroid hit the earth at the end of the Cretaceous and that caused the end of the Cretaceous period. Before the KT boundary, pollen from angiosperms and gymnosperms is high. After the meteor hits the earth, a mass extinction occurs and the amount of pollen from gymnosperms and angiosperms decreases dramatically, while the amount of spores from ferns increases. During the Cretaceous period there were many species of gymnosperms and angiosperms but they disappeared at the KT boundary, when the asteroid hit the earth.
The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.
B. they are single molecules...
<span>The answer would be: No, the baby is most likely in the REM sleep stage

One of the cycles of sleep called Rapid Eye Movement or REM. In this cycle, the eye is moving constantly and intermittently. The eye movement is not voluntary and the baby is not a sign of waking up. This cycle is important, so the parent should not interrupt it by waking the baby.
