Where is the Earth’s energy coming from?
the sun Nearly all of the earth's energy comes from the sun. Some of this radiant energy is reflected by water droplets and dust particles in the atmosphere and bounced back into space or scattered throughout the atmosphere; some is absorbed by clouds or ozone.
What are external processes of the Earth?
The forces that act on the surface of the earth due to natural agents like running water, glacier, wind, waves, etc., are called External processes or Exogenetic processes. These external processes tear the landscape down into relatively low elevated plains and shapes the landform created by Endogenetic process.
What is external and internal processes?
The forces that act from the Earth's interior toward the Earth's surface are called Internal processes. The forces that act on the surface of the Earth due to natural agents like running water, glacier, wind, waves etc., are called External processes. These forces build the landscape and create topographic relief.
What are the elements of disaster risk explain the significance of each disaster risk element in determining the odds of a disaster happening and its impacts?
Risk is a combination of three components: hazard, exposure, and vulnerability. Data from each of these categories can be used to paint a picture of risk in a certain location and over time. Hazard – a potentially destructive physical phenomenon (e.g., an earthquake, a windstorm, a flood).
What is vulnerability and risk of disaster Class 9?
According to the definition of vulnerability, it is "the state in which an individual, a community, assets, or systems are more susceptible to the effects of risks due to physical, social, economic, or environmental causes or processes."
What are external processes of the earth?
The forces that act on the surface of the earth due to natural agents like running water, glacier, wind, waves, etc., are called External processes or Exogenetic processes. These external processes tear the landscape down into relatively low elevated plains and shapes the landform created by Endogenetic process.
What is an external process and give example of it?
Concept of external processes. These include weathering, wind action, surface and groundwater, the sea ice. These processes, unlike domestic occurring on the surface or upper crust. Differ and external processes that derive no energy inside the planet, and outside.
What is the external process of Earth?
The forces that act on the surface of the earth due to natural agents like running water, glacier, wind, waves, etc., are called External processes or Exogenetic processes. These external processes tear the landscape down into relatively low elevated plains and shapes the landform created by Endogenetic process.
What is a external source?
External sources means information from any source other than the Internal Sources, including information from licensed or subscription-based licensed (e.g. OVID, Dialog, RSS aggregator databases) sources and non-licensed (e.g. Yahoo, MSN, CNN) sources.
What is the main source of energy?
The primary sources of energy in the environment include fuels like coal, oil, natural gas, uranium, and biomass. All primary source fuels except biomass are non- renewable. Primary sources also include renewable sources such as sunlight, wind, moving water, and geothermal energy.
What is the primary source of energy?
Primary energy sources take many forms, including nuclear energy, fossil energy — like oil, coal and natural gas — and renewable sources like wind, solar, geothermal and hydropower.
What’s external process?
Answer: External processes shape the relief created by internal processes. External agents carry out this process: water, ice, wind, atmosphere and human beings. They include all the changes that alter or wear down the rocks and deposit materials resulting from erosion.
What is external process powered by?
They are called external processes because they occur at or near Earth's surface and are powered by energy from the Sun. By contrast, internal processes, such as volcanism and mountain building, derive their energy from Earth's interior.
What is external process of the earth?
The forces that act on the surface of the earth due to natural agents like running water, glacier, wind, waves, etc., are called External processes or Exogenetic processes. These external processes tear the landscape down into relatively low elevated plains and shapes the landform created by Endogenetic process.
What is external process?
1. The business processes that cannot be executed without involvement of an external business partner such as the customer relationship management process. Learn more in: Major Techniques and Current Developments of Supply Chain Process Modelling.
How does vulnerability exposure and hazard related to disaster risk?
Exposure represents the stock of property and infrastructure exposed to a hazard, and it can include socioeconomic factors. Vulnerability accounts for the susceptibility to damage of the assets exposed to the forces generated by the hazard.
What are the different processes involved in disaster risk management?
The ultimate goal of the disaster-management leader is to minimize the event's impact, something that involves preparedness, response, recovery and mitigation.
What is disaster BYJU’s?
A disaster is defined as a disruption on a massive scale, either natural or man-made, occurring in short or long periods. Disasters can lead to human, material, economic or environmental hardships, which can be beyond the bearable capacity of the affected society.
What is disaster management name the disaster management agencies involved in India?
The National Disaster Management Authority (NDMA), headed by the Prime Minister of India, is the apex body for Disaster Management in India. Setting up of NDMA and the creation of an enabling environment for institutional mechanisms at the State and District levels is mandated by the Disaster Management Act, 2005.
What is mean by external processes?

What is internal and external source?
1. Meaning. Internal sources of finance represent means of generating funds by the business itself from its own operations. External sources of funds represents means of generating funds through outside entities.
What is the most common source of external recruiting?
Media Advertisement: The advertisement is the most common and preferred source of external recruiting. The ads in newspapers, professional journals, give a comprehensive detail about the organization, type, and nature of job position, skills required, qualification and experience expected, etc.
What are the main sources of energy found on Earth?
The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells. The sun heats the earth's surface and the Earth heats the air above it, causing wind.
What is the main source of energy for life on Earth?
The Sun 3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
What is the primary source of energy on Earth and why?
The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells. The sun heats the earth's surface and the Earth heats the air above it, causing wind.
