Which component of magma includes mobile ions of silicon?
Lemur [1.5K]

Answer:

Melt.

Explanation:

When rocks melt, they do so slowly and gradually because most rocks are made of several minerals, which all have different melting points; moreover, the physical and chemical relationships controlling the melting are complex. As a rock melts, for example, its volume changes. When enough rock is melted, the small globules of melt link up and soften the rock.

Under normal conditions, mantle rock like peridotite shouldn't melt in the Earth's upper mantle. However, by adding water you can lower the melting point of the rock. Alternatively, by decompressing the rock, you can bring it to a pressure where the melting point is lower. In both cases, basalt magma will form and considering it is hotter and less dense than the surrounding rock, it will percolate towards the surface and some of that erupts.

What is the total resistance of the circuit? (must include unit - ohms) I WILL GIVE BRAINLIEST!
ICE Princess25 [194]

Answer: 4 ohms

Explanation:

For parallel connection we use this formula

R=equivalent resistance

R1=24 ohms

R2=8 ohms

R3=12 ohms

1/R=1/R1 + 1/R2 + 1/R3

1/R=1/24 + 1/8 + 1/12

1/R=(1x1+3x1+2x1) ➗ 24

Cross multiplying we get

24x1=(1x1+3x1+2x1) x R

24=(1+3+2) x R

24=6xR

Divide both sides by 6

24 ➗ 6=6xR ➗ 6

4=R

R=4 ohms
