What type of stresses broke Earth’s lithosphere into plates Group of answer choices?
The type of stresses that broke the Earth's lithosphere into plates are the tectonic forces. Tectonic forces come from the movement of the mantle and…
What are the circumstances under which convection can occur?
What are the circumstances under which convection can occur in a substance? accretion, differentiation, and radioactivity.
Which terrestrial world has the strongest magnetic field?
Earth's magnetic field is categorized as moderately strong, the gas giants and ice giants have extremely strong magnetic fields, Mercury has a weak magnetic field, while Mars and Venus have no measurable magnetic fields. Jupiter is the largest planet in the Solar System and therefore has the strongest magnetic field.
What process has shaped Earth’s surface more than any other?
What process has shaped Earth's surface more than any other? shield volcano on Mars. How did the lunar maria form? Large impacts fractured the Moon's lithosphere, allowing lava to fill the impact basins.
What caused Earth’s lithosphere to fracture into plates?
They found that while there was global cooling in Earth's early years, the outer shell was warming at the same time, which is the most likely cause behind our planet's crust breaking apart.
What is tectonic stress explain the main types of stress?
Compressive stress happens at convergent plate boundaries where two plates move toward each other. Tensional stress happens at divergent plate boundaries where two plates are moving away from each other. Shear stress is experienced at transform boundaries where two plates are sliding past each other.
Which of the following is an example of convection?
Convection is a form of heat transfer where a large number of molecules move from one place to another. An overhead fan works precisely by this method: it sends cooler air molecules down into a hot room, cooling the temperature of the room.
What drives the motion of the continental plates on Earth quizlet?
Earth's lithosphere is broken up into plates that float on the underlying mantle. The tops of the mantle's convection cells drag the bottoms of the plates, making them move. This movement causes spreading in some places and subduction in others.
Which planet has no magnetic field?
Mercury was thought to be cold and dead inside, thus having no magnetic field.
What planet has the shortest year?
Mercury Fastest Planet The closer a planet is to the Sun, the faster it travels. Since Mercury is the fastest planet and has the shortest distance to travel around the Sun, it has the shortest year of all the planets in our solar system – 88 days.
What caused Earth’s lithosphere to fracture into plates quizlet?
The plate consists of continental or oceanic crust and the cool, rigid upper mantle directly below the crust. The theory that Earth's lithosphere is fractured into plates that move relative to each other and are driven by convection currents in the mantle. Most volcanic and seismic activity occurs at plate margins.
What are the 4 processes that shape the Earth’s surface?
What processes shape Earth's surface? The four major geological processes are impact cratering, volcanism, tectonics, and erosion.
What causes cracks in the lithosphere?
Since the lithosphere is chilled and more solid, it traps convective heat from the core underneath it. That heat would've made the lithosphere begin to expand again, and the cracking would take place.
What are the types of stresses in the earth’s crust?
The three main types of stress are typical of the three types of plate boundaries: compression at convergent boundaries, tension at divergent boundaries, and shear at transform boundaries.
What are the three types of differential stress in the Earth’s lithosphere?
Three kinds of differential stress occur.
- Tensional stress (or extensional stress), which stretches rock;
- Compressional stress, which squeezes rock; and.
- Shear stress, which result in slippage and translation.

What are examples of conduction convection and radiation?
Example of situation with conduction, convection, and radiation
- Conduction: Touching a stove and being burned. Ice cooling down your hand. …
- Convection: Hot air rising, cooling, and falling (convection currents) …
- Radiation: Heat from the sun warming your face.

What is conduction convection and radiation?
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission.
What causes Earth’s tectonic plates to move?
The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.
What are the forces thought to cause plate tectonic movement quizlet?
Three forces act on the plates to make them move: basal drag from convection currents, ridge push at mid-ocean ridges, and slab pull from subducting plates. Convection currents in the mantle produce a force that causes motion called basal drag.
Why is Mars red?
Well, a lot of rocks on Mars are full of iron, and when they're exposed to the great outdoors, they 'oxidize' and turn reddish – the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.
Has water been discovered on Mars?
On November 22, 2016, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Mars. The volume of water detected has been estimated to be equivalent to the volume of water in Lake Superior.
How old would I be on Pluto?
A year on Pluto is almost 248 Earth years long. This means that every living human is less than one Pluto year old.
How long is 1 day in space?
The definition of a day is the amount of time it takes an astronomical object to complete one full spin on its axis….The Earth is the only planet with an approximately 24-hour day.
| Planet | Length of Day |
|---|---|
| Earth | 23 hours, 56 minutes |
| Mars | 24 hours, 37 minutes |
| Jupiter | 9 hours, 55 minutes |
| Saturn | 10 hours, 33 minutes |

What drives the motion of the tectonic plates on Earth?
The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
What are the three forces that alter the surface of the Earth?
Wind, water, and ice are the three agents of erosion, or the carrying away of rock, sediment, and soil. Erosion is distinguished from weathering — the physical or chemical breakdown of the minerals in rock. However, weathering and erosion can happen simultaneously.
What are the 4 geologic processes?
Geological processes
- Erosion. Erosion involves the movement of rock fragments through gravity, wind, rain, rivers, oceans and glaciers.
- Weathering. Weathering is the wearing down or breaking of rocks while they are in place.
- Deposition. …
- Landforms. …
- Relief.
What is a crack or break in the lithosphere?
Faults are cracks in the earth's crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small. If tension builds up along a fault and then is suddenly released, the result is an earthquake.
What is the tension stress?
Tensional stress is the stress that tends to pull something apart. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.
What causes stress in the lithosphere?
The ultimate source of lithospheric stress is thermal cooling of the earth which leads to density differences and the concomitant buoyancy forces that act on both the asthenosphere and lithosphere.
Is Earth’s mantle conduction convection or radiation?
Convection Convection occurs in the Earth's mantle because it is the most efficient way for the Earth to cool or dispose of its deep-seated heat content. In general, heat can be transferred by conduction, radiation or convection.
