earth science exam questions with correct answers 2023/2024

earth science exam questions with correct answers 2023/2024 True or false. The four major Earth systems are the atmosphere, lithosphere, hydrosphere, and geosphere. - Answer-False. Atmosphere, geosphere, hydrosphere, and biosphere. True or False. A scientific theory is a statement that describes what scientists expect to happen every time under certain conditions. - Answer-True What are are Earth's four spheres? - Answer-Atmosphere, geosphere, biosphere, hydrosphere. What are the five branches of Earth Science - Answer-Geology, oceanography meteorology, astronomy, and environmental science. What do they study? - Answer-Geologists study the lithosphere. Oceanographers study the hydrosphere. Meteorologists study the atmosphere. Astronomers focus beyond the Earth System and study the systems of other planets and heavenly bodies. And environmental scientists might study the atmosphere, biosphere, or hydrosphere. What type of Earth scientist would study the ways of predicting earthquakes? Explain your answer. - Answer-A seismologist would study the different ways to predicting earthquakes. Seismology is a branch of geology in which earthquakes are studied. Describe the type of attitude that would help to make a good scientist. - Answer-Being curious is the type of attitude that would help make a good scientist. This is because the scientist would want to experiment and test everything they see. How might a geologist study the history of Earth? - Answer-Geologist might study the layers of rock that make up the lithosphere to investigate events that have happened in the past, to try to find and date fossils, etc. Explain why scientists might use models to represent Earth's processes. - Answer-We use models in order to represent Earth's processes on a smaller scale so that it is easier to study them. Describe the process of scientific inquiry and explain why it is not a rigid sequence of steps. - Answer-Scientific inquiry is a process of posing questions, forming a hypothesis, designing an experiment, collecting and interpreting data, drawing conclusions, and communicating. Why is the scientific inquiry not a rigid sequence of steps? - Answer-The scientific inquiry is not a rigid sequence of steps because you can always redo a step. For example, you can always change your hypothesis, redo an experiment. Earth is comprised of four systems, or spheres. Give one example of how a change in one of these spheres of the Earth can affect one or more of the other spheres. - Answer-An earthquake, which is part of the lithosphere, may change the course of a river, which is part pf the hydrosphere. The shifting course of the river could affect the plants and animals of the area, which are part of the biosphere.
