The document summarizes key aspects of the hydrologic cycle and Earth's water systems. It describes the hydrologic cycle as a series of interconnected water storage areas and transfer processes. It discusses the oceans, which contain over 97% of Earth's water, and how ocean waters vary in salinity, temperature, and density around the world. It also outlines various freshwater storage areas like lakes, rivers, groundwater, and glaciers, and how humans have impacted some of these systems through activities like irrigation and groundwater extraction.

Wind has the ability to shape the surface of the Earth. Wind is one of the greatest agents of land erosion and transportation. The action of wind is very significant in arid and semi-arid regions. Due to profound wetness, wind cannot act in humid regions. Wind is capable of eroding, transporting and depositing the surface materials, in drylands. The landforms created by wind action are called as Aeolian landforms. The word “Aeolian” is derived from the Greek word “Aeolus”, meaning, the god of the winds.
Geological work of the wind, deflation, wind abrasion, desert pavement,
ventifacts, desert dunes and sand sheets, sand seas or ergs, loess, coastal dunes, sand hills and
sabkhas, loess and evolution of deserts: Wind action and desert landscape

This is our group work in our science subject. We are assigned to make a power point presentation in order for us to understand and share our knowledge in the given chapter. We hope that you learned from the presentation the we have presented, thank you and good luck!
This power point presentation is all about water resources and its characteristics.It is presented by Ram Angeles and Frank Gutierrez of section 11- San Juan from Rizal Technological University
This document covers rivers from the CSEC Geography syllabus. It covers the water cycle, drainage basin, drainage density, drainage patterns, river processes, characteristics of rivers and river landforms
