ABE 101 Principles of Soil Science and Engineering Lecture 1: AN INTRODUCTION Engr. May Rose Boston-Osoteo Instructor FUNDAMENTAL CONCEPTS AND DEFINITIONS Soil is basic of all natural resources 2 3 GLOBAL SYSTEM AND ITS COMPONENTS Earth has four different spheres or domains that are affected by climate: ❑Atmosphere ❑Hydrosphere ❑Lithosphere ❑Biosphere 4 GLOBAL SYSTEM AND ITS COMPONENTS Layers of the Atmosphere 5 GLOBAL SYSTEM AND ITS COMPONENTS Hydrosphere ¤ It includes all water on the surface of the earth oceans, lakes, rivers, aquifers, and ice. ¤70% of the earth’s surface is covered with water. 6 GLOBAL SYSTEM AND ITS COMPONENTS Lithosphere 7 GLOBAL SYSTEM AND ITS COMPONENTS Lithosphere covers the remaining 30% between 0 and 40 km thick consists of igneous, metamorphic, and sedimentary rock 8 GLOBAL SYSTEM AND ITS COMPONENTS ROCK CYCLE 9 GLOBAL SYSTEM AND ITS COMPONENTS Biosphere 10 Assignment 1. Discuss the nitrogen cycle and its processes. 2. Discuss the hydrologic cycle and its processes. 11 END OF PRESENTATION 12
