What are the two principal sources of heat in the Earth Which has a greater contribution tosurface heat flux?
The two principal sources of heat are the Sun and the Earth itself via geothermal heat.
The sun's heat will vary more than geothermal, and therefore contribute more to flux.

What are the principal sources of groundwater?
The principal sources of groundwater are rainfall and snowmelt that infiltrate the ground and percolate through soil and rock layers. Groundwater can also come from surface water bodies like rivers and lakes that recharge aquifers through infiltration. Additionally, groundwater can originate from artificial sources such as irrigation or leaking water supply systems.
Describe the Earths principal sources of internal and external energy?
The Earth's principal sources of internal energy are radioactive decay of elements in the Earth's core and residual heat from the planet's formation. External energy sources include solar radiation, which drives processes like weather patterns, ocean currents, and ecosystems. Together, these energy sources contribute to the dynamic processes shaping Earth's geology and climate.
What is the best reason to use a renewable source instead of relying on fossil fuels?
Using renewable sources is more sustainable as it reduces greenhouse gas emissions, mitigates climate change, and helps to preserve natural resources for future generations. Additionally, renewable energy sources are inexhaustible and can lead to greater energy independence and security.
Why would the use of alternative sources of energy be beneficial to the Earth and its people?
Alternate sources of energy are renewable (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass, biofuel and hydrogen). They emit no carbon dioxide pollution, so make no contribution to global warming, unlike fossil fuels (coal, oil and natural gas).
What are the three principal sources of internal heat of terrestrial planets?
The three principal internal sources of heat for the terrestrial planets are;accretion,differentiation,radioactivity.The first two mainly occur during the planets formation. Accretion, as gas, dust and smaller bodies collide to form the planet, generating heat on impact and differentiation. Differentiation is the process where the most dense outer material falls to the centre of the planet heating the core through friction during accretion. The source of the thermal energy is the gravitational potential energy which the extended mass had before accretion. The planet holds this heat for billions of years.Radioactive material was present in the original accretion disk. The long lived radioactive elements decay for billions of years. (On Earth, these are potassium-40, uranium-238, uranium-235, and thorium-232.) This also contributes significantly to internal heating, as unstable radioactive nuclei split and release energy (fission).
What sources are in each book of the Pentateuch?
The principal sources for Genesis were the Yahwist, the Elohist and the Priestly Source.The principal sources for Exodus were the Yahwist, the Elohist and the Priestly Source.The principal source for Leviticus was the Priestly Source.The principal source for Numbers was the Priestly Source, with some material by the Yahwist.The principal sources for Deuteronomy was the Deuteronomist, who was also responsible for the Deuteronomic History.The JE Redactor combined early material by the Yahwist and the Elohist and may have made minor changes to content. The final Redactor redacted the books into much the form we know today and made minor changes to content.
What are the principal sources of groundwater?
The principal sources of groundwater are rainfall and snowmelt that infiltrate the ground and percolate through soil and rock layers. Groundwater can also come from surface water bodies like rivers and lakes that recharge aquifers through infiltration. Additionally, groundwater can originate from artificial sources such as irrigation or leaking water supply systems.
What has the author SALLY HARPER written?

Why competitors important for any organization?
the principal sources of competitive advantage are lower costs of production and a differentiated product offering.

What are the principal data sources in experimental and quasi-experimental research?
Do your research and stop looking for the easy way out. You'll find the answer with a little time and effort.
Where did jade come from?
Burma (Myanmar) and Guatemala are the principal sources of modern gem jadeite. In the area of Mogaung in the Myitkyina District of Upper Burma (Myanmar)
What is Composite supply?
The composite supply rule applies where there is a principal element as well as an ancillary element or elements being supplied and where the ancillary elements would not realistically be sold on their own without the principal element. Such ancillary supplies are not physically and economically dissociable from the principal supply.
That you won't forget any sources when should you prepare a works cited list?
You should prepare a works cited list whenever you use sources in your writing to give credit to the original authors and avoid plagiarism. It is important to include all sources you have referenced or quoted in your work to acknowledge their contribution and provide a way for readers to locate the original sources.
What are the mechanism of pollution?
Two principal mechanisms for water pollution are point sources and nonpoint sources. Point sources are specific locations of industrial discharge, such as a pipe that dumps into a river. Nonpoint sources is pollution that does not originate from a single point. Urban runoff and agricultural pollution are nonpoint sources.
