Compare earth and mars in paragraph plz
Studentka2010 [4]

Answer:

Hey buddy, here is your answer. Hope it helps you.

Explanation:

Atmospheric pressure and temperatures are another way in which Earth and Mars are quite different. Earth has a dense atmosphere composed of five main layers – the Troposphere, the Stratosphere, the Mesosphere, the Thermosphere, and the Exosphere. Mars' is very thin by comparison, with pressure ranging from 0.4 – 0.87 kPa – which is equivalent to about 1% of Earth's at sea level. When it comes to magnetic fields, Earth and Mars are in stark contrast to each other. On Earth, the dynamo effect created by the rotation of Earth's inner core, relative to the rotation of the planet, generates the currents which are presumed to be the source of its magnetic field. The presence of this field is of extreme importance to both Earth's atmosphere and to life on Earth as we know it.In terms of their size and mass, Earth and Mars are quite different. With a mean radius of 6371 km and a mass of 5.97×1024 kg, Earth is the fifth largest and fifth most-massive planet in the Solar System, and the largest of the terrestrial planets. Mars, meanwhile, has a radius of approximately 3,396 km at its equator (3,376 km at its polar regions), which is the equivalent of roughly 0.53 Earths. However, it's mass is just 6.4185 x 1023 kg, which is around 15% that of Earth's.Earth and Mars are similar when it comes to their basic makeups, given that they are both terrestrial planets. This means that both are differentiated between a dense metallic core and an overlying mantle and crust composed of less dense materials (like silicate rock). However, Earth's density is higher than that of Mars – 5.514 g/cm3 compared to 3.93 g/cm3 (or 0.71 Earths) – which indicates that Mars' core region contains more lighter elements than Earth's.

Why are felsic lava flows so much more viscous than mafic ones?
ira [324]

Answer:

Magma are the hot molten materials that rises up towards the surface due to the increasing force from the depth. These magma when comes out to the surface then they are considered as lava.

The felsic lava are those in which the amount of silica and aluminium is very high. Due to this high silica content, the viscosity is high. The amount of silica present in magma or lava is directly proportional to the viscosity of magma or lava. The felsic lava due to its high viscosity flows sluggishly.

Whereas, the basic lava are those in which the silica content is significantly less. Iron (Fe) and Magnesium (Mg) is mostly present in this type of lava. As a result of which it flows easily without any difficulty.

This is the reason why felsic magma (lava) are more viscous compared to the mafic magma (lava).
