1 Science STAAR Review Changes to Land Sun, Earth, and Moon Space

2 Changes to Land Wind, water, and ice can change Earth’s surface. 1.Weathering is the breakdown of Earths crust into smaller particles called sediment. 2.Erosion carries away the sediment to another location. 3.Deposition is the building up (depositing) of new land in a location

3 Changes to Land Sand dunes form when wind-blown sand builds up Deltas form when water-born sediments are deposited at the mouths of rivers.

4 Changes to Land Canyons form when moving water cuts through the Earth’s surface.

5 Properties of Soil Soil can be sorted based on particle size, texture, color, and capacity to retain water.

6 Properties of Soil

7 Patterns on Earth We can collect and analyze data to predict patterns of change observable on Earth. Shadows are caused by objects blocking light. Tides are caused by the tug of the Moon’s gravitational pull on the oceans as the Moon moves around Earth.

8 Patterns on Earth Seasons occur when the Earth revolves around the Sun once a year and the tilt of the Earth on its axis

9 Patterns on Earth The Moon’s appearance changes in the same pattern each month and can be predicted. Takes about 30 days to complete one cycle.

10 Water Cycle/ Hydrologic Cycle The Sun provides the energy that evaporates water on Earth. Water that evaporates from the ocean does not contain salt.

11 Earth’s Rotation The day and night cycle occurs every 24 hours due to the rotation of the Earth. We can demonstrate that the rotation of the Earth causes the day/night cycle.

12 Earth’s Rotation The Sun appears to move across the sky each day due to the rotation of the Earth. The apparent path of the Sun changes with the seasons.

13 Earth, Sun, and Moon The Sun is made of gases, while the Earth and Moon are made largely from rock.

17 The Sun and Earth have very different atmospheres, while the Moon does not have an atmosphere, and only the Earth has liquid water.

18 Planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
