Mid-Ocean Ridges

Two examples of Mid-Ocean Ridges are the Mid-Atlantic Ridge and the East Pacific Rise.

Explanation:

Mid-ocean ridges are mountain-like geographical features on the ocean floor. They usually line along the divergent boundaries of tectonic plates moving away from each other. This is because as the plates move in opposite direction, the vacuum in between the plates is filled by upwelling magma from the mantle. Usually the texture of the rocks that form these mountain ridges has bands. This is because, before the magma cools, the iron in the magma (due to its ferromagnetic property) aligns with the earths magnetic field. The earth magnetic flux flips over several 1000 years hence these bands orient themselves differently depending on the magnetic field orientation at the time they were formed.

Arrange the following elements in order of increasing from smallest to largest atomic size K,O, Cs, Se explain why the reason wh
lyudmila [28]

Answer:

smallest is O then Se then K then Cs.

Explanation:

These trends exist. elements tend to get smaller as it completes it's shell since there is more attraction when it is complete. plus the further down the periodic table you go the bigger it is. there are more electrons which repulse each other and make it bigger.

A student measures the mass of an 8 cm block of brown sugar to be 12.9 g. What is the density of
horrorfan [7]

Answer:

0.0025g/cm³

Explanation:

Given parameters:

Mass of the brown sugar = 12.9g

dimension of the sugar = 8cm

unknown:

density of the sugar = ?

Solution

Density is defined as the mass per unit volume of a substance. The expression is given below:

      Density = \frac{mass}{volume}

We know the mass of the substance but the volume is unknown:

Volume of the brown sugar = l x bx h = 8x8x8 = 512cm³

Density of the brown sugar = \frac{12.9}{512} = 0.0025g/cm³
