What Energy Source Is Earth Using Primarily For Its Internal Processes??
Solar Power. The Sun is Earth’s main source of energy making the development of solar power a natural choice for an alternative energy source.
What energy source is earth using primarily for its internal heat?
Geothermal energy is heat that is generated within the Earth. (Geo means “earth ” and thermal means “heat” in Greek.) It is a renewable resource that can be harvested for human use. About 2 900 kilometers (1 800 miles) below the Earth’s crust or surface is the hottest part of our planet: the core.
When hiking up most Stratovolcanoes which rock composition’s will you see from its base to its summit?
Felsic from bottom to top.
What are these circles themselves individually depicting?
Type in your answers above into the boxes provided on the webpage and hit “Find Epicenter”. The next screen will be a map showing circles. What are these circles themselves individually depicting? The correct answer is: It is an estimate of the total amount of energy released by an earthquake.
Which type of wave below can travel through solids and liquids and is similar to a sound wave select one?
earthquakes. The P seismic waves travel as elastic motions at the highest speeds. They are longitudinal waves that can be transmitted by both solid and liquid materials in the Earth’s interior. With P waves the particles of the medium vibrate in a manner similar to sound waves—the…
Why is the Earth’s interior hot What is the source of the Earth’s internal energy?
What were sources of Earth’s original internal heat quizlet?
What are the sources of Earth’s internal heat? The sources of heat inside the Earth are leftover heat from Earth’s formation and Radioactive decay.
Which composition of rocks are primarily found at and near the surface of oceanic hot spot volcanism?
What happens to allow the sand to be deposited and create the spit?
What happens to allow the sand to be deposited and create the spit? Energy decreases within the longshore current. At the end of the summer season which would you expect to see at a typical beach: Much less sand piled up on the beach relative to the end of the winter season.
What makes a cinder cone steep sided?
A Cinder cone volcano doesn’t last very long at all they are small and the are made rom moderately explosive eruptions (NOT LONG RUNNING LAVA OVER SEVERAL YEARS LIKE THE SHIELD Volcano). The cinder cone has steep sides because they sides erode quickly because the pyroclastic material isn’t cemented in very well.
Where does the sand on our beaches in California primarily originate from?
In general sand comes from weathering of continental granitic and sedimentary rocks (the most common sources) weathering of oceanic volcanic rocks (basalts) and skeletal remains and shells of organisms (carbonates). The sand on our beaches is made up of the rocks and soil of California.
What type of plate boundary are shallow focus earthquakes associated with?
Which layer listed below can also be considered a tectonic plate?
Tectonic plates are composed of Earth’s crust and the uppermost rigid portion of the mantle. Together they are called the lithosphere . Earth’s crust comes in 2 “flavors”: oceanic and continental (Table 1.1).
Which type of waves travel through the interior of the earth?
The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.
What is the wave that can travel through the Earth’s inner layer?
Which of the following waves can travel inside the Earth?
There are three major kinds of seismic waves: P S and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth and are not trapped near the surface.
What role does the Earth’s internal heat play in the planet’s internal processes?
How does the Earth generate its heat from the inside?
The process by which Earth makes heat is called radioactive decay. … Many of the rocks in Earth’s crust and interior undergo this process of radioactive decay . This process produces subatomic particles that zip away and later collide with surrounding material inside the Earth.
What were the main sources of Earth’s original internal heat?
Radioactive potassium uranium and thorium are thought to be the three main sources of heat in the Earth’s interior aside from that generated by the formation of the planet.
What are the two primary sources of Earth’s internal energy quizlet?
The Earth has two basic sources of energy – that reaching the Earth from the Sun (Solar Energy) and that reaching the surface of the Earth the Earth itself (Internal or Geothermal Energy).
Which of the following are sources of Earth’s internal heat?
The flow of heat from Earth’s interior to the surface is estimated at 47±2 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust and the primordial heat left over from the formation of Earth.
Which of the following sources of energy represent the main sources of Earth’s internal heat?
Regarding origin of the heat the current consensus is that the flow of heat from Earth’s interior to the surface comes from two main sources: radiogenic heat and primordial heat.
Where do hotspots occur?
How do mafic volcanic rocks get to Earth’s surface?
How do mafic volcanic rocks get to Earth’s surface? Pressure from overlying crust forces mantle magmas through cracks to Earth’s surface. These magmas erupt out of volcanoes cool and solidify into rock. Dark colored glassy rock that usually forms when highly silica rich lava cools quickly at Earth’s surface.
Where are hotspots located?
Most of these are located under plate interiors (for example the African Plate) but some occur near diverging plate boundaries. Some are concentrated near the mid-oceanic ridge system such as beneath Iceland the Azores and the Galapagos Islands. A few hotspots are thought to exist below the North American Plate.
What transports sand to the location the spit is created in?
What transports sand to the location the spit is created in? A spit is formed from the deposition of material longshore drift transports the material along the coastline and it builds up to create a spit.
Is Smith volcano active?
Why does the earth need volcanoes?
Without volcanoes most of Earth’s water would still be trapped in the crust and mantle. Early volcanic eruptions led to the Earth’s second atmosphere which led to Earth’s modern atmosphere. Besides water and air volcanoes are responsible for land another necessity for many life forms.
How hot is lava?
The temperature of lava flow is usually about 700° to 1 250° Celsius which is 2 000° Fahrenheit. Deep inside the earth usually at about 150 kilometers the temperature is hot enough that some small part of the rocks begins to melt. Once that happens the magma (molten rock) will rise toward the surface (it floats).
Where is sand on Earth?
Does sand come from fish poop?
The famous white-sand beaches of Hawaii for example actually come from the poop of parrotfish. The fish bite and scrape algae off of rocks and dead corals with their parrot-like beaks grind up the inedible calcium-carbonate reef material (made mostly of coral skeletons) in their guts and then excrete it as sand.
Where does sand come from in the ocean?
Most beaches get their sand from rocks on land. Over time rain ice wind heat cold and even plants and animals break rock into smaller pieces. This weathering may begin with large boulders that break into smaller rocks. Water running through cracks erodes the rock.
What type of plate boundary has shallow intermediate and deep earthquakes?
convergent plate boundaries
At divergent plate boundaries earthquakes tend to be weak and shallow. Transform plate boundaries have shallow but very powerful earthquakes. At convergent plate boundaries where two continental plates collide earthquakes are deep and also very powerful.
