Earth is changing every day. Erosion makes giant mountains smaller and rivers wider, but it happens so slowly most people don't even notice. Do you know what erosion is? Or what causes it? Explore the amazing eroding world in this book.
Landforms are features on the earth's surface that are made naturally. Mountains, plains, and plateaus are all examples of landforms. The study of landforms is called geomorphology. Scientists can learn about the past and even predict future changes by studying landforms. Today we can take pictures of landforms from airplanes and satellites.
Audisee® eBooks with Audio combine professional narration and text highlighting for an engaging read aloud experience! Igneous rocks, sedimentary rocks, and metamorphic rocks make up the three main types of rocks. But did you know that rocks are constantly being created, destroyed, and created again? Or that rocks are changed by weather, erosion, heat, and pressure? See the rock cycle in action in this fascinating book.
Examines the different forces of erosion, such as wind, waves, acid rain, and glaciers and explains how those forces affect the topography of the earth.--
Climate Change Impact on Soil Erosion in Sub-tropical Environment by Subodh Chandra Pal,Rabin Chakrabortty Pdf
This work focuses on the potential impact of climate change on soil erosion in a monsoon-dominated sub-tropical region. Water-induced soil erosion due to extreme rainfall during the monsoon period is a major problem worldwide, from different environmental and socio-economic perspectives. This study region covered (South Bengal) is one of the fertile agricultural belts that produces a good amount of produce and contributes to the country's GDP. However, the rate of agricultural output has decreased rapidly in recent times due to a decline in soil fertility. The monsoon-dominated sub-tropical region has unique characteristics in terms of seasonal temperature fluctuations and the availability of rainfall events. The sub-tropical region is densely populated, with the majority of the population relying on rain-fed agricultural production systems. The declining rate of agricultural production has also established that soil fertility is declining and soil erosion is increasing. Numerous studies show that soil erosion is the major cause of the region's rapidly increasing trend of land degradation. A homeostatic mechanism cannot replace soil erosion, and a gap arises between soil erosion and regolith formation. Extreme changes in land use and land cover, population growth and the lacking support for traditional agricultural practices and management practices can accelerate the rate of soil erosion and its associated reservoir sedimentation in most countries of the tropical and sub-tropical environment. Quantitative information with maximum possible accuracy through validation regarding soil loss can be an essential part of the appropriate and sustainable soil and water conservation planning. The precise aspects of modern day management strategies are soil erosion susceptibility mapping using empirical and semi-empirical models in a GIS platform or the use of probability statistics. The main objective of this work is to propose the most suitable development strategies considering the amount of soil erosion for the present and future periods. Extensive field research has been done to identify the support practice factor that the local stakeholders adopt in this region.
New Standards-Based Lessons for the Busy Elementary School Librarian by Joyce Keeling Pdf
This book provides targeted and invaluable help for the busy elementary school librarian and the science teacher as they work together to design and co-teach library-based lessons guided by the Next Generation Science Standards, English Literacy Common Core Standards, and the new AASL Standards. All standards are cited in easy-to-use reproducible lessons. Energy-packed and interactive lessons are coordinated to common elementary science curricula at the grade level indicated and are also adaptable and usable as template lessons as needed. Necessary handouts and other tools, with current lists of recommended resources, are provided. Elementary school librarians and classroom teachers as well as curriculum coordinators, elementary reading, social studies, and science instructors will find value in this collection of lessons. The highly rated materials recommended in the resource lists are valuable for aiding librarians in collection development to support new and current standards.
A Look at Erosion and Weathering by Cecelia H. Brannon Pdf
Full-page photos and graphs illustrate the topics covered, while easy-to-comprehend text helps readers understand the concepts of erosion and weathering, including the difference between these two processes and how they affect rocks in the rock cycle.
Soil erosion: the greatest challenge for sustainable soil management by Food and Agriculture Organization of the United Nations Pdf
Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.

Weathering as a Predisposing Factor to Slope Movements by Domenico Calcaterra,Mario Parise Pdf
This volume is intended to provide an up-to-date overview of the approaches, methodologies and techniques devoted to better understand-ing of the weathering conditions of rock masses on slopes. According to the local conditions, a variety of slope movements may take place and involve weathered rock masses. Shallow and rapid soil slips evolving to debris flows are probably the most common type of slope movement. At the same time, deep-seated, intermittent landslides can also affect large volumes of weathered rocks and soils. Despite the high frequency of landslides in weathered materials, and the damage and casualties they repeatedly cause, little is known about the relationship between weathering and slope move-ments. This book presents worldwide case studies, where a variety of geo-logical and geomorphological settings are discussed. The content is divided into three sections: the first is devoted to broad aspects of the weathering/landslide processes; the second and third sections include papers dealing with igneous/metamorphic and sedimentary weathered rocks, respec-tively.
