What type of current is caused by wind on the oceans surface?
Surface ocean currents are caused by winds. As wind blows across the surface, the wind pulls the water and causes waves.
What describes a cause of lithospheric plate movement across the surface of earth?
the plates are driven across the surface by convection currents within the plastic rock of the asthenosphere.
When a line of clouds move across the sky what is it a example of?
convection currents
What process drives the lithospheric plates across the surface of earth?
The process that drives the movement of lithospheric plates across the surface of the Earth is called plate tectonics. This movement is mainly driven by the heat generated from radioactive decay in the Earth's interior, which creates convection currents in the semi-fluid asthenosphere beneath the lithosphere. These convection currents cause the lithospheric plates to move, leading to phenomena like seafloor spreading, subduction, and continental drift.
What is the cause of the currents that make plates move across the earth?
The currents that drive plate movement are caused by the heat generated from the Earth's core. This heat creates convection currents in the mantle, which in turn move the tectonic plates on the Earth's surface.
What is a good sentence for surface currents?
Surface currents can be very fast on water.
How can you use sunspots to tell that the sun is rotating on its axis?
Sunspots can be used to determine the rotation period of the Sun because they appear to move across the Sun's surface as it rotates. By tracking the motion of sunspots over time, scientists can calculate the rotation period of the Sun. This information helps confirm that the Sun is indeed rotating on its axis.
Why are Earth's continental plates continually in motion?
Earth's continental plates are in motion due to the movement of molten rock in the Earth's mantle. This movement, known as mantle convection, transfers heat and creates the forces that push and pull the plates in different directions, causing them to move across the surface of the Earth. The continuous motion of the plates is driven by the Earth's internal heat and the resulting convection currents in the mantle.
What Convection currents resulting from uneven heating of earths surface causes what?
Convection currents resulting from uneven heating of the Earth's surface cause the movement of air and water in the atmosphere and oceans, leading to weather patterns and climate systems. These currents are driven by temperature differences; warmer, less dense material rises while cooler, denser material sinks. This process is crucial for phenomena such as wind formation, ocean currents, and the distribution of heat across the planet. Ultimately, it plays a significant role in shaping ecosystems and influencing global weather.
What are two convection currents?
Two examples of convection currents are atmospheric circulation and ocean currents. In the atmosphere, warm air rises near the equator, cools, and then sinks, creating wind patterns. In the ocean, warm water near the surface moves toward the poles while cooler, denser water sinks and flows back toward the equator, driving large-scale ocean currents. Both processes help regulate temperature and distribute energy across the Earth.
How does convection transfer heat from one place to another on the earth?
Convection transfers heat on Earth by the movement of fluids, such as air and water, in response to temperature differences. As warmer fluids rise and cooler fluids sink, they create currents that redistribute heat across the Earth's surface. This process helps regulate temperature, weather patterns, and ocean currents.
What are tectonic plates driven by?
Tectonic plates are driven by the movement of material in the Earth's mantle. This movement is caused by heat from the Earth's core, which creates convection currents within the mantle. As the currents rise and cool, they push the tectonic plates apart, causing them to move across the Earth's surface.
