Course Introduction

Earth and Space Science offers a comprehensive exploration of the physical processes that shape our planet and the universe beyond. This course investigates Earth's structure, composition, and dynamic systems, including the atmosphere, hydrosphere, and geosphere, and examines how these systems interact to drive phenomena such as weather, climate, and plate tectonics. Additionally, students will study the solar system, stars, galaxies, and cosmology, fostering an understanding of the origin and evolution of celestial bodies. Emphasis is placed on scientific inquiry, evidence-based reasoning, and the interdependence between human activity and Earth's systems, preparing students to evaluate contemporary issues like natural hazards and space exploration.

Q1) The four extra minutes in the solar day are due to our ________ around the Sun.

Answer: revolution

Q2) If the angular diameter of an object is 15 arc seconds and it is 1.4 billion kilometers away,how big is its physical size? Show how you arrived at your answer.

Answer: Use the equation above Example 3 in More Precisely 1-2 to complete the calculation.15" = 15/60/60 degrees = 1/240 degree (about 0.0042 degrees).Then the diameter = distance × angular size / 57.3 degrees = 1.4 × 10 km × 1/240 / 57.3 100,000 km.
