the Earth’s surface‚ climate changes depending on where the location is on the planet. Factors such as incoming solar energy‚ Earth’s rotation‚ and air and water movements all affect an area’s climate. Different levels of these factors influence the biomes on the planet. The current climate change is the warming of Earth’s atmosphere. Climate change has happened naturally all throughout history‚ but never to the degree that it is now. Average global temperature and CO2 levels are rising due to human

African Savannas The African Savanna is one of the largest tropical grasslands in the world. Tropical grasslands are known to have 90-150 cm of rainfall every year‚ a large area filled with grass‚ and being warm year round with a dry and rainy period. The climate in an African Savanna can range from 68o to 86oF. There are two seasons that are dry and wet on the environment‚ the winter lasts from October to March. The dry climate is caused by the lack of precipitation which can result in droughts

Biodiversity is a measure of the health of ecosystems. Greater biodiversity implies greater health. Biodiversity is in part a function of climate. In terrestrial habitats‚ tropical regions are typically rich whereas polar regions

A soil horizon is a layer parallel to the soil surface‚ whose physical characteristics differ from the layers above and beneath. Each soil type has at least one‚ usually three or four horizons. Horizons are defined in most cases by obvious physical features‚ chiefly colour and texture. These may be described both in absolute terms (particle size distribution for texture‚ for instance) and in terms relative to the surrounding material‚ i.e. ‘coarser’ or ‘sandier’ than the horizons above and below

Every single say we affect the lithosphere‚ whether we know it or not. Simple things just like a little rain effects it. Ways that processes and forces affect the lithosphere is water. When it runs off it causes chemical reactions that break down rocks. The rainwater dissolves the rocks to form caves and to move rock and soil to other places. By doing this is causes major erosion. Erosion is very bad because it slowly breaks away soil‚ and takes out all the nutrients that plants need to survive.

Name and describe the attributes of the two categories into which all organisms can be divided based on how they obtain nutrition. All organisms can be divided into autothrops‚ which produce their own food‚ and heterothrops‚ which need to get their food from somewhere else. 3. Name and describe the roles of the three main trophic categories that make

The Littoral Zone The littoral zone‚ commonly referred to as the intertidal area‚ is where the land and water meet. It is rich in nutrients and oxygen and is home to a variety of organisms. The littoral zone provides some plants with the opportunity to complete their growth cycle‚ but the changing water level also brings about some environmental problems‚ such as soil erosion and biodiversity reduction (Chen). The word littoral means shore. Therefore‚ the littoral zone of a pond is
