Studying and exploring spaceEdwin Powell Hubble (1889-1953) was an American astronomer who, in 1923, showed that the universe is expanding. He used photographs to prove that there are galaxies beyond our own. Prior to this, scientists believed that our galaxy was the entire universe. In 1990, the Hubble Space Telescope (clearly named in honor of the great 20th century astronomer) was launched by NASA and has provided some of the most spectacular images of the universe ever seen.

Earth's energy resourcesRenewable resources are resources that can be replenished in a reasonable amount of time. Nonrenewable resources are resources that, once consumed, cannot be replaced. Because oil, natural gas, and coal are the products of plants and organisms, they are known as fossil fuels. Fossil fuels are ultimately a limited resource, it is important to develop and use renewable energy resources. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 1

Earth's Fresh WaterFresh water moves over the surface by an interconnected system of streams and rivers. Small streams that feed water into larger rivers are called tributaries. Rivers are closely interconnected and flow from higher to lower elevations where the water collects in larger and larger rivers until it ultimately flows into the oceans.

Groundwater ResourcesGroundwater is fresh water stored in regolith and bedrock. Even though solid rock like granite or marble has no pores, it often has a series of cracks and possibly faults. Water accumulates in the cracks in solid bedrock and, at times, is a source of water. A layer of rock material that can store water and allow the movement of water through the ground is called an aquifer. Read more...iWorksheets: 3Study Guides: 1Vocabulary Sets: 2
