What evidence supports Hess's theory of seafloor spreading? Check all that apply.
Zarrin [17]

The direction iron in ocean rocks points

The new crust, formed at constructive/divergent boundary (regarding tectonic plate movement), has band-like patterns that orient in different directions (in alignment with earth's magnetic fields) and visible on the surface. This shows that it is newly made crust made from new magma.

Explanation:

These bands are firmed when the iron minerals in magma orient themselves with the earth's magnetic field before the magma cols into rock and lock the minerals permanently in position. This magma upwells from the mantle to fill the void made when the tectonic plates are moving away from each other.

The earth's magnetic field on the other hand is dynamic. Its angle increases gradually from the true north or south and then flips orientation over several hundred years. The iron minerals therefore will align differently depending on the orientation of the earths magnetic field at the time. This is why the new crust has band-like features visible on its surface.

What is the pressure of 0.540 mol of an ideal gas at 35.5 L and 223 K?
Inga [223]

Answer:

Pressure, P = 28.2 kPa

Explanation:

Given that,

Number of moles, n = 0.54 mol

Volume of ideal gas, V = 35.5 L

Temperature, T = 223 K

We need to find the pressure of ideal gas. The equation of ideal gas is given by :

PV=nRT

R is gas constant

P is pressure

P=\dfrac{nRT}{V}\\\\P=\dfrac{0.54\ mol\times 8.314\ kPa- L/mol- K\times 223\ K}{35.5\ L}\\\\P=28.2\ kPa

So, the pressure of the gas is 28.2 kPa.
