can't see anything sorry can't help
Answer and explanation;
-The cause of convention currents in a hot spring is rainwater and melted snow is cool and denser and sinks to the bottom of the hot spring where it is heated by a shallow magma chamber. The heated water expands and is less dense and rises to the top.
Explanation;
-Convention Current is the movement of fluid caused by the differences in temperature. Transference of heat from one part of a fluid to another.
-Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.
The layers form from sand dunes
Answer:
use hot water
Explanation:
hot water helps dissolve things faster
Depending on the surface area and weight, either can fall slower.
<u>Explanation:
</u>
If you were to drop a feather and a brick off a building at the same height, the brick would reach the ground first. This is due to air resistance and how it slows the feather down compared to the brick. The surface area of the feather creates more resistance compared to its weight, therefore it hits the ground slower. It really all depends on the surface area, weight and the air resistance it creates.
If all air resistance were to be removed, then what would happen is that the two objects would fall and reach the ground at the same time. This is because the objects are in free fall, and because they are in free fall, the two objects would be falling at an acceleration of 9.81 m/s². This is true for all objects in free fall.
