Answer:
D. magnetic polarity reversals
Explanation:
The marine magnetic anomalies are the result of two things; the seafloor spreading at the mid-ocean ridges and the magnetic polarity reversals.
The mid-ocean ridges are the places where the new crust forms. This places also have big influence on the magnetic anomalies, with the reason being that the magnetism has higher influence in this parts.
Also, the magnetic polarity reversals play a big role. The Earth has not always had the same magnetic polarity, and multiple times throughout its past the North and South Poles have been switching places when it comes to the magnetism.
The igneous rocks on the ocean floor have proof in them about this, as the metallic components are reacting to the magnetism and face toward the stronger magnetic field.
Not erupt at all, but remain in the magma chamber and cool .
Afrikaans is a language.
So the answer is option D.

Answer:
Polar air masses derived from areas close to Iceland and tropical masses from the Azores bring, respectively, very different conditions of temperature
Explanation:
Answer:
Question 14. Option b
Question 15. Option a
Question 16. option c
Explanation:
Question 14.:
Regardless of the heaviness of the Ash particles inside it blended with the hot volcanic gases, this is the light comparative with the cold encompassing air.
It rises convectively over the thrust area and is known as the convective ascent region of the emission section.
Question 15.:
Since the gravity isn't so solid on Mars and Mercury Lava streams can be thicker as a result of which they don't cool so quick when contrasted with the earth. Little cone volcanoes on Mars would tend to be in general more extensive and shorter.
Question 16.:
Cryovolcano is otherwise called the ice spring of gushing lava. What's more, cryovolcanism is a method where the ejection of magma from ice happens as opposed to rock in molten form. Cryo Magma or the cryo magma or ice volcanic liquefy are normally fluids or vapor.
