Answer:Solar flares

Explanation:

Answer: Solar Flares

Explanation: The Sun's magnetic field goes through a cycle, called the solar cycle or known as solar flares. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun's north and south poles to flip back again.

Stephan’s mother is a mineralogist, and sometimes she brings home samples to study. Stephan observesand compares these minerals. He knows minerals form in several ways. He is especially interested in the minerals that form from volcanic activity and the kinds of crystals they form. What determines crystal size in minerals formed by lava or magma?
A. the kind of mineral that formed
B. the amount of material available
C. the rate at which the minerals cooled
D. the materials in the lava or magma

Answers

D!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The rate at which the minerals cooled determines the crystal size in minerals formed by lava or magma. The correct option is C.

What determines crystal size in minerals?

The solution is extremely saturated with some minerals, crystals form as magma cools. The crystals are quite tiny because they did not have much time to form if the magma cooled quickly. The crystals have ample time to form and become huge if the magma cools gradually.

The rate at which the minerals cooled Crystal size in minerals formed by lava or magma is primarily determined by the rate at which the minerals cooled.

When lava or magma cools slowly, it allows crystals to grow larger. Conversely, when it cools rapidly, crystals have less time to grow and thus remain smaller.

Therefore, the correct option is C.

Well as you might know, water is one of the most important abiotic factors essential for life. Without water, consumers would have nothing to drink. The plants under the water body might die too as they wouldn’t be able to photosynthesize. If the plants die, there’s less oxygen for the tiny water creatures. Some water creatures might die as well. If other animals don’t have water to drink, they’re going to die as well. Therefore, without water, most biotic factors would probably die due to the lack of efficiency in them performing life processes like photosynthesis and cellular respiration.

Describe the movement of Earth’s mantle. Explain how convection currents can cause tectonic plates to move.

Answers

Answer:

Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.

Convection currents from core radioactive decay rise and fall in the mantle. Convection currents move plates. Plates separate near convection currents. Plates converge at convection currents.

What are convection currents?

Convection currents are caused by differential heating. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.

Convection currents are produced by radioactive decay in the core and are caused by heat rising and falling inside the mantle. The plates are moved by convection currents. Plates separate where convection currents split close to the Earth's crust. Plates move in the direction of one another where convection currents converge.
