Name given to icy areas at top and bottom of earth?
The icy areas at the top and bottom of the Earth are called the Arctic (at the North Pole) and the Antarctic (at the South Pole).
Why cant convection currents form if they are heated from the top?
Convection currents form when a fluid is heated from the bottom, causing it to rise and create a circulating flow. If a fluid is heated from the top, there is no temperature difference to drive the circulation, preventing convection currents from forming. Heat needs to be applied at the bottom to induce the necessary buoyancy-driven flow for convection currents to occur.
The layers of the earths atmosphere from top to bottom are the?
In descending order: exosphere, thermosphere, mesosphere, stratosphere, troposphere.
What marks the tyop and bottom of the earth?
The top of the Earth is marked by the North Pole, while the bottom is marked by the South Pole. These points are located at the ends of Earth's axis of rotation, where the lines of longitude converge.
What do you call the movement when heat rises to the top on Earth?
The movement of heat rising to the top on Earth is called convection. It occurs because heated materials become less dense and rise, while cooler materials become denser and sink, creating a circulation pattern.
Does the earth have a top and a bottom?
The Earth's top and bottom are defined by the North and South poles, respectively. The concept of top and bottom is based on human perception, as Earth is a sphere with no true top or bottom in space.
How do convention currents move?
Heated from the bottom, the warmer substance will slowly rise to the top while the cooler substance at the top falls to the bottom to be heated again. Look at a lava lamp. That is all about convection currents.
What are the flat bits at the top and the bottom of the earth called?
The earth is round, due to gravity, so there are no flat bits at the top and bottom.
Why does the Earth's crust move on top of the magma when getting heated by the earth's core?
Convection currents move the magma around in circles up and down as it gets cooled and heated. And the plates move on top of them.
What is hemisphere's?
Top or bottom half of the earth
Is the southern hemisphere the bottom part of the Earth?
No, the top.
Where is earth wire attached to?
it is the top or bottom of the equipment..........
Why doesnt convection occur when a beaker is heated at the top?
Convection occurs when heated fluid rises and cooler fluid sinks, creating a continuous circulation. If a beaker is heated at the top, the heated fluid near the top would rise but due to cooler fluid at the bottom, the circulation does not sustain itself, thus preventing convection from occurring.
Name given to icy areas at top and bottom of earth?
The icy areas at the top and bottom of the Earth are called the Arctic (at the North Pole) and the Antarctic (at the South Pole).
Is Antarctica on the top of the Earth or on the bottom?
Antarctica is located at the southern most point on the earth and encompasses the South Pole. Basically, it's at the bottom of the earth.
The distance from the top to the bottom of the Earth is called?
Latitude
What is line that splits the earth from the top to the bottom?
a line of longitude
