 The study of the origin, history, and structure of the Earth and the processes that shape the Earth is called Geology The scientific study of the sea is called Oceanography The study of the Earth’s atmosphere, especially in relation to weather and climate, is called Meteorology ___________ study stars, asteroids, planets, and everything else in space. Astronomers _____________ are a series of steps that scientists use to answer questions and solve problems. Scientific Method ______________ is a possible explanation or answer to a question that can be tested. Hypothesis A ________________ is an experiment that tests only one factor, or variable, at a time. All other variables remain constant. By changing only one variable, scientists can see the results of just that one change. If more than one variable is changed, scientists cannot easily determine which variable caused the outcome. controlled experiment A pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept is a ___________. model ____________ are models that you can touch. Physical models A _______________is made up of mathematical equations and data mathematical model ____________________ models are composed of many hypotheses. Each hypothesis is supported through scientific methods. Conceptual ___________is an explanation that ties together many hypotheses and observations. A ________ not only can explain an observation you have made but also can predict what might happen in the future. (same answer for both blanks) theory Scientists who study the Earth’s atmosphere have developed mathematical climate models to try to imitate Earth’s climate.
