- Wind and air masses. Heated ground causes air to rise which results in lower air pressure. ...
- Elevation. The higher up you are, the colder and drier it will be. ...
- Relief.
What is environment and environmental pollution?
Environmental pollution is defined as “ the contamination of the physical and biological components of the earth/atmosphere system to such an extent that normal environmental processes are adversely affected . From: Environmental Management, 2017.
What are the factors that affect global warming?
Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
What are some examples of environmental changes?
Examples of these global environmental changes include climate change, freshwater shortages , loss of biodiversity (with consequent changes to functioning of ecosystems), and exhaustion of fisheries.
What are the two most important environmental factors affecting animals?
What are the two most important environmental factors affecting animals? Temperature and Water . Temperature and water are important abiotic factors that affect species distribution.
What are 4 environmental factors that can harm a fetus?
Environmental factors which have been implicated in adverse pregnancy outcome include smoking, video display terminals, anesthetic gases, antineoplastic drugs and exposure to lead, selenium and inorganic mercury .
What are the 4 environmental factors that affect your health?
A number of specific environmental issues can impede human health and wellness. These issues include chemical pollution, air pollution, climate change, disease-causing microbes, lack of access to health care, poor infrastructure, and poor water quality .
What are the 3 types of ecological factors?
The three types of ecological factors are: (1) Climatic factors which include rainfall, atmospheric humidity, wind, atmospheric gases, temperature and light (2) Physiographic factors which include altitude, effect of steepness and sunlight on vegetation and direction of slopes (3) Biotic factors which include ...
What are general environmental factors?
When considering strategic business decisions, businesses analyze the six general environmental forces: political, economic, sociocultural, technology, environment and legal factors .

What is a natural change in an ecosystem?
Wind, rain, predation and earthquakes are all examples of natural processes which impact an ecosystem. ... Anything that enters an ecosystem – from sunlight to rain to contaminants – has the potential to change it. Scientists refer to these factors as drivers.
What are the environmental factors that affect human growth and development?

How do environmental changes affect organisms?
When an environment changes, differences between individuals can allow some plants and animals to survive while others die or move to new locations . ... Environmental changes allow animals to survive, adapt, and vary. All animals survive when the environment changes, which leads to their variations and adaptations.
How do ecosystems respond to environmental change?
One way that some freshwater organisms respond to environmental change is to evolve rapidly . A marked change in the environment favors some characteristics of plants, animals and microbes over others. ... The shorter the generation time, the faster this evolutionary change can occur.
What changes in natural ecosystems are caused by the ongoing global warming process?
Climate change is increasing air and water temperatures, altering precipitation patterns , intensifying many natural disturbances, affecting species distribution and survival, and changing ocean chemistry, among other impacts.
