Mantle material rises in convection currents because heated materials become less dense.
<h3>What is convection current?</h3>
- Convection is a single- or multiphase fluid movement that develops on its own as a result of the interaction between a fluid's body forces—most frequently gravity and density—and material property heterogeneity.
- Differential heating leads to convection currents. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. When a fluid's one component is heated, the difference in temperatures causes the fluid to flow in a particular direction.
- The process of a heated fluid rising and being replaced by a cooler one is known as convection cycle.
- Convection currents use the mass motion of a fluid, such as water, air, or molten rock, to move heat from one location to another. The earth's ocean currents, atmospheric weather, and geology are all controlled by convection currents' capacity to transport heat.

Answer:
The Ring of Fire
The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth’s volcanoes and earthquakes take place along the Ring of Fire.
Answer:
b. An island 30 hectares in size that is 10 kilometers off the coast of the mainland
Explanation:
- Based on the theory of the island biography the highest number of the species would be found in the islands that have to be an island of the 30 hectares and is separate from the mainland coasts at a distance of the 10 km. And various factors affect the species diversity and richness of the isolated systems with a specific relationship to the oceanic islands.
I believe absolute location is when you give an exant location of where you are and a relative location is just and area your in.
FOR EXAMPLE:
absolute location: I live on South West baker Street at 3410.
relative location: I live in Miami, Florida
A watershed is a certain area that separates water from flowing into rivers/seas.
