Earth Science Exam Questions with Complete Solutions Latest Update What are the five areas of study that Earth Science emcompasses? - Answer-1. astronomy, 2. meteorology, 3. geology, 4. oceanography and 5. environmental science Scientists use Scientific Methods to investigate. - Answer-... Scientists use Scientific Methods to investigate. - Answer-The temperature of the earth's core is 7227 C. What percentage of freshwater is contained in glaciers - Answer-70% What is the CRUST? - Answer-thin, rocky outer lay of the earth, used as the hardened exterior or surface part of the bread. Astronomy - Answer-The study of objects beyond Earth's atmosphere meteorology - Answer-The study of the forces and processes that cause the atmosphere to change and produce weather geology - Answer-The study of the materials that make up Earth, the processes that form and change these materials, and the history of the planet and its life-forms since its origin Geologists identify rocks, study glacial movements, interpret clues to Earth's 4.6-billion-year history, and determine how forces change our planet. oceanography - Answer-The study of Earth's oceans, which cover nearly three-fourths of the planet. Oceanographers study the creatures that inhabit salt water, measure different physical and chemical properties of the oceans, and observe various processes in these bodies of water. environmental science - Answer-The study of the interactions of organisms and their surroundings. Environmental scientists study how organisms impact the environment both positively and negatively. The topics an environmental scientist might study include natural resources, pollution, alternative energy sources, and the impact of humans on the atmosphere. geosphere - Answer-The area from the surface of Earth down to its center. The geosphere is divided into three main parts: the crust, mantle, and core. atmosphere - Answer-the mass of air surrounding the Earth hydrosphere - Answer-the watery layer of the earth's surface biosphere - Answer-The biosphere includes all organisms on Earth as well as the environments in which they live. Most organisms live within a few meters of Earth's surface, but some exist deep beneath the ocean's surface, and others live high atop Earth's mountains. All of Earth's life-forms require interaction with at least one of the other systems for their survival. Earth is divided into four independent systems. Name the systems. - Answer-geosphere hydrosphere atmosphere biosphere
