EARTH SURFACE REALMS 2And3 We can look at Earth’s surficial "layers" as being comprised of several major realms or "geospheres": the atmosphere‚ lithosphere‚ hydrosphere‚ biosphere and pedosphere. The reference to "sphere" applies because Earth is spherical‚ and hence layers around it form somewhat spherical shells at the outermost edges of the solid planet. The atmosphere‚ biosphere and lithosphere more completely encircle Earth‚ while the hydrosphere and pedosphere tend to be more discontinuous

Food Chain: A sequence that links species by their feeding relationships. Herbivores: Organisms that only eat plants. Carnivores: Organisms that only eat animals. Omnivores: Organisms that eat both plants and animals. Detritivores: Organisms that eat detritus‚ or dead organic matter. Specialist: A consumer that primary eats one specific organism. Generalist: Consumer that has varying diet. Trophic levels: The levels of nourishment in a food chain. Food Web: Shows the network of feeding relationships

Abstract Based on regional-scale studies‚ aboveground production and litter decomposition are thought to positively covary‚ because they are driven by shared biotic and climatic factors. Until now we have been unable to test whether production and decomposition are generally coupled across climatically dissimilar regions‚ because we lacked replicated data collected within a single vegetation type across multiple regions‚ obfuscating the drivers and generality of the association between production

Introduction to Physical Geography Homework: Chapter 15 Key Terms and Concepts (1-24) 1. Denudation is the total effect of all actions (weathering‚ mass wasting‚ and erosion) that lower the surface of the continents. 2. Weathering- the physical and chemical disintegration of rock that is exposed to the atmosphere. Mass-wasting- the short-distance down slope movement of weathered rock under the direct influence of gravity; also called mass movement. Erosion- detachment‚ removal‚ and transportation

Most negative impacts came from land-based sources. Oils spills‚ garbage‚ acidification‚ untreated sewage‚ overfishing and marine litter are prime examples of negative impacts humans did to the marine biome. People have done positive impacts also to keep animals living in the marine biome living. Humans have picked up trash from beaches‚ prevented oil spills‚ watched what they put down sinks‚ prevented dumping waste into the ocean and many other positive things. Predation is the relationship

I. WHAT IS GLOBAL WARMING? Global warming is the gradual increase of the Earth’s average measured temperature overtime. This measured average temperature is derived from both the near-surface air as well as ocean waters. Scientists began measuring this temperature beginning in the mid-20th century and have continued to monitor fluctuations and deviations in measurements ever since. The average global temperature increased approximately 1.33°F over the past 100 years ending in 2005. This led the

Foreststation to Savannization The Savanna biome‚ distinct with its climates and organism‚ will have a major impact on the present and future life forms of Earth. This being predicted by Jose D. Anadón‚ Osvaldo E. Sala and Fernando T. Maestre‚ the authors and researchers of Climate change will increase savannas at the expense of forests and treeless vegetation in tropical and subtropical Americas.The authors work explores the dimensions of the impact of climate change on biomes that have received little attention

The freshwater biome | A lake at Acadia National Park‚ Maine. | Freshwater is defined as having a low salt concentration — usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e.‚ ocean). There are different types of freshwater regions: * Ponds and lakes * Streams and rivers * WetlandsPonds and lakes These regions range in size from just a few square meters to thousands
