Earth Science Exam Questions
Course Introduction
Earth Science is an interdisciplinary course that explores the dynamic processes and physical characteristics of our planet. Students will examine the four main spheres of Earth: the geosphere, hydrosphere, atmosphere, and biosphere, studying how these systems interact to shape landforms, influence weather and climate, and support life. Topics include plate tectonics, earthquakes, volcanoes, the rock cycle, natural resources, and environmental issues. Through laboratory investigations, field studies, and analysis of current events, students gain a deeper understanding of Earths history, structure, and the role of human activity in shaping the environment.

Q2) Describe two reasons why an address may be geocoded in an incorrect location. Answer: There are many possible answers to this question.Some reasons may be;1)the address given may be out of range of the span of addresses listed for a link; 2)the street may have been typed incorrectly (or be called something else); 3)linear interpolation may place the point at an incorrect location along the line since the actual housing numbers may not directly coincide with the range of addresses present in the database; 4)the street may not be present in the database (for instance,a new housing development may not have been added to the reference database yet); and 5)an address point may end up matched to the center of a zip code rather than a street address.
