Answer:
Porosity
Explanation:
Porosity is defined as the total percentage of pore spaces that are present within a rock. These spaces are found between the rock particles and fractures and are mostly filled with fluid mixture or water. It is the ratio between the total pore space in a rock to the total volume of the rock. It is mainly calculated in terms of percentage.
Porosity is directly affected by sorting. Well-sorted rocks indicate high porosity but poorly-sorted rocks indicate low porosity. Some of the examples of rocks exhibiting high porosity are limestone, shale, and sandstone. Rocks with low porosity include granite and mudstone.
Features that are typical for the divergent plate boundaries are:
- <em>ocean ridges;</em>
Underwater mountain chains that are very long and are marking the border of the plates.
- <em>formation of new crust;</em>
Since the crust is very weakened and loose, the high temperature, pressure, and magma, are able to penetrate it and create new crust.
- <em>intense volcanic activity;</em>
The high amount of magma penetrating from the mantle layer is causing intense volcanic activity, thus the creating on new crust, and underwater mountain chains.

Answer:
<u>Pluto is dwarf planet composed of nitrogen ice, methane and carbon monoxide.</u>
Explanation:
Designated as a minor planet pluto is considered to be on the outer boundaries of the planets, being found in the 1930s is the ninth largest and the tenth object orbiting the sun.
Its atmosphere is mainly composed of methane, nitrogen and carbon monoxide and ice. Having a mass of that of the moon, it has mountains made up of ice masses its color varies from dark brown to orange to white. The latest studies show that pluto has an age of more than 180,000 years.
According to some studies it has mass wasting and tectonic like processes in operational at its surface. It is surface gravity is 0.63g and has five known natural satellites. A mean density of 1.854±0.006 g/cm cube.
