lived on Earth. However‚ 65 million years ago‚ the most recent mass extinction seemed to have caused all of them to die-off. What caused the demise of the dinosaurs and 60% of life on Earth at the time? How did it affect life on Earth afterwards? Are all of the Dinosaurs dead? Will this happen to humans in the near future? The Cretaceous-Tertiary extinction event‚ or the K-T event‚ is the name given to the mass extinction of the dinosaurs and other species that took place about 65 million years

Objective: The main objective is to demonstrate the law of Conservation of Mass. Use Vinegar and baking soda to demonstrate the law of Conservation of Mass. Introduction: The law of Conservation of Mass states that mass is neither created nor destroyed during ordinary chemical reactions or physical changes‚ which means that no matter how dramatic of a change that a substance goes through‚ it will not lose mass. It may seem like it lost mass‚ and usually‚ if you weighed the result‚ it will have

less heeded. The importance of soil conservation is relatively less talked about as compared to the conservation of water and other natural resources. The almost-omnipresent soil is mostly taken for granted. Its omnipresence is ironically the reason behind us‚ human beings‚ taking it for a ride. We rarely even think of it as a natural resource that needs to be conserved‚ a part of the natural wealth that needs to be preserved. The concept of the conservation of soil takes into account‚ the strategies

kingdom and human society at large depend upon soil for their sustenance directly or indirectly. Ironically‚ soil is the most neglected commodity on the earth. Shifting cultivation on the hill slopes‚ non-adoption of soil conservation techniques‚ and over exploitation of land for crop production due to population stress‚ leads to enormous soil erosion. It will take hundreds of years to form an inch of soil‚ but in no time it gets washed away down the slope due to erosion. SOIL CONSERVATION Soil

The roles of Zoos in conservation The main aim of zoos is to protect and conserve global biodiversity and wildlife. To do this they have four roles to play which are; research‚ conservation‚ education and welfare. Research: Research is the careful search or inquiry for new facts by scientific study of a subject‚ through a course of critical investigation. By studying animals we can learn new things about their behaviour and lifestyle. The Secretary of State’s Standards of Modern Zoo Practice (SSSMZP)

Wildlife conservation encompasses all human activities and efforts directed to preserve wild animals from extinction. It involves both protection and scientific management of wild species and their environment. Some species have become extinct due to natural causes‚ but the greatest danger to wildlife results from the activities of man. So we ourselves have created the need for conservation of wildlife. It can be viewed from several angles such as‚ beauty‚‚ economic value‚ scientific values for
