Why was the discovery of mid ocean ridges important to geologists studying continental drift?
When molten lava is coming out of the mid-ocean ridges, it turns to solid rock. The solid rock pushes the land that's already there, so more land will come. That separates the continents, so it was important for geologists to study that.
Can the rock magnetite lose its magnetism?
The rock magnetite can only very rarely lose all of its magnetism. It is an important source and tool for magnetism and the testing of equipment in laboratories.
Which mineral is harder galena or magnetite?
magnetite is harder than galena. Magnetite has a hardness just under glass, so around 5. Galena sits at around 4 on mohs hardness scale
What is the diaphaneity of magnetite?
The diaphaneity of magnetite is opaque.
How can you tell the difference between hematite and pyrite?
The difference between the iron in magnetite and hematite is the charge. Hematite has all 3+ iron ( the iron when make the mineral loses 3 electrons) and magnetite has some 2+ iron (it only loses 2 electrons).
Is magnetite a silicate?
Magnetite is Iron and Oxygen. So no, it is considered an oxide.
What are the most important tools that geologists use?
The most important tool that geologists use is called a trowel
Why are extinction events important to geologists?
what is important of events
The magnetic iron oxide mineral is called?

Why is the work of geologists important?
The world needs mineral resources to manufacture the various artifacts which our civilization depends upon; geologists help us to locate those resources.
What minerals are important in ores of iron?
Magnetite, hematite, and limonite.Hematite ....... I think?
What important mineral was found in Arizona?

Why is the theory of plate tectonic so important to geologists?
because it gives scientists a way to study and predict geologic events.

magnetite is harder than galena. Magnetite has a hardness just under glass, so around 5. Galena sits at around 4 on mohs hardness scale
Is magnetite a metal?
Magnetite is an oxide of iron which occurs in igneous rocks, and in veins and replacement deposits; it is one of the most important ores of iron. It usually occurs as a coarse, granular mass of black octahedral crystals, and produces a black streak. Magnetite is permanently magnetic, and was the first magnetic material to be discovered, known then as lodestone.
