60 | ChaPTer 2 Earth Science Earth science is concerned with the study of Earth and its place in the solar system.

They should recognize that most of Earth’s surface is covered by water and be able to describe where fresh and salt water are found. At this level, assessment of students’ understandings of the atmosphere is limited to evidence for the existence of air and the presence of water in the air. Students are also expected to know common features of Earth’s landscape and have some understanding of the uses and conservation of Earth’s resources. In the area of Earth’s processes, cycles, and history, fourth- grade students are expected to be able to describe some of Earth’s processes in terms of observable changes, including the movement of water, cloud formation, and changes in daily or seasonal weather conditions.
