Which factor has the greatest influence on the number of daylight hours that a particular earth surface location?
Our amount of daylight hours depends on our latitude and how Earth orbits the sun. Earth's axis of rotation is tilted from its orbital plane and always points in the same direction — toward the North Star.
When a continental crustal plate collides?
Plates Collide When two plates carrying continents collide, the continental crust buckles and rocks pile up, creating towering mountain ranges. The Himalayas were born when the Indian subcontinent smashed into Asia 45 million years ago.
When a continental crustal plate collides with an oceanic crustal plate the continental crust is forced to move over the oceanic crust?
When a continental crustal plate collides with an oceanic crustal plate, the continental crust is forced to move over the oceanic crust. What is the primary reason that the continental crust stays on top of the oceanic crust? (1) Continental crust is less dense.
Which is the major source of energy for most earth processes?
The Sun is Earth's primary source of energy.
What is the primary function of the clear glass of the greenhouse quizlet?
What is the primary function of the clear glass of the greenhouse ? The glass allows short wavelengths of radiation to enter, but reduces the amount of long wavelength radiation that escapes.
What causes the changes in the sun angle and length of daylight that occur during the course of a year?
The “fixed” tilt means that, during our orbit around our Sun each year, different parts of Earth receive sunlight for different lengths of time. It also means that the angle at which sunlight strikes different parts of Earth's surface changes through the year.
What is the meaning of Convergent in science?
Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction.
What geologic structures are associated with convergent boundaries?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common at subduction zones as well.
When oceanic crust meets oceanic crust along a convergent boundary which plate is to be subducted?
denser plate If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate.
When two tectonic plates collide the oceanic crust usually subducts beneath the continental crust because it is?
When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser. Convergent boundaries are commonly associated with larger earthquakes and higher volcanic activity.
Which is the primary source of energy and how does it affect the climate of the earth?
The Sun is the primary source of energy for Earth's climate system is the first of seven Essential Principles of Climate Sciences. Principle 1 sets the stage for understanding Earth's climate system and energy balance. The Sun warms the planet, drives the hydrologic cycle, and makes life on Earth possible.
What are the primary sources of energy that drive the movement of matter among reservoirs?
The Sun provides the energy that drives the water cycle on Earth. 2.5 Movement of matter between reservoirs is driven by Earth's internal and external sources of energy. These movements are often accompanied by a change in the physical and chemical properties of the matter.
How do greenhouse gases get into our atmosphere?
Emitted primarily through the burning of fossil fuels (oil, natural gas, and coal), solid waste, and trees and wood products. Changes in land use also play a role. Deforestation and soil degradation add carbon dioxide to the atmosphere, while forest regrowth takes it out of the atmosphere.
Why do greenhouse gases contribute to global warming?
Greenhouse gases The main driver of climate change is the greenhouse effect. Some gases in the Earth's atmosphere act a bit like the glass in a greenhouse, trapping the sun's heat and stopping it from leaking back into space and causing global warming.
How does the angle of sunlight affect surface temperature?
Angle of Solar Radiation and Temperature At higher latitudes, the angle of solar radiation is smaller, causing energy to be spread over a larger area of the surface and cooler temperatures.
How do the tilt of Earth’s axis and Earth’s movements around the sun cause seasons?
The Short Answer: Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
What do you think a divergent constructive boundary is how do plates interact with each other?
Divergent boundaries are areas where plates move away from each other, forming either mid-ocean ridges or rift valleys. These are also known as constructive boundaries. Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.
What does divergent plate boundary mean in science terms?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.
Which plate boundary and movement commonly create non volcanic mountains explain how non volcanic mountains are created by plate tectonics?
Answer and Explanation: The convergent boundary is one where the impact of the two plates towards one another results in the formation of non-volcanic mountains.
When oceanic crust meet with continental crust it is called oceanic continental convergence?
Ocean-Continent Convergence. When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The entire region is known as a subduction zone.
Why does earthquake occur in subduction zone ?( The area where subduction occur?
Why do so many earthquakes originate in this region? The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking (or subducting) beneath another plate. Earthquakes in these subduction zones are caused by slip between plates and rupture within plates.
What is the primary source of solar energy?
the sun One of the most important sources of energy is the sun. 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.
What is the primary source of energy which causes changes in the weather?
Sun is the primary cause of change in the weather.
What is the primary source of heat?
One of the most important sources of energy is the sun. 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.
What is the primary source of heat on Earth?
A major source of Earth's heat is radioactivity, the energy released when the unstable atoms decay. The radioactive isotopes uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th) in Earth's mantle are the primary source.
How do greenhouses work?
A greenhouse works by converting light energy into heat. Light enters the greenhouse and is trapped there by the glass and absorbed by the plants and other objects. This causes the light energy to be converted to heat energy, which is trapped inside the greenhouse.
What do greenhouse gases do?
Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere.
How does greenhouse effect work?
The greenhouse effect: some of the infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. The effect of this is to warm the Earth's surface and the lower atmosphere.
How does latitude The angular distance of a place north or south of the equator relate with the solar energy received?
The lowest latitudes get the most energy from the Sun. The highest latitudes get the least. The difference in solar energy received at different latitudes drives atmospheric circulation. Places that get more solar energy have more heat.
How does latitude affect solar radiation?
At higher latitudes, the angle of solar radiation is smaller, causing energy to be spread over a larger area of the surface and cooler temperatures.
