Answer:

D. lignite

Explanation:

The lignite is a type of coal. It is the type of coal that is ranked at the bottom by its heating capacity, as all other types of coal produce more heat than it. The percentage of carbon in this type of coal varies between 60 and 70%, which is actually the main reason why it produces the least amount of heat, as it has the lowest consistence of carbon. Because the carbon is in lower amount, this type of coal also has lighter coloration than the other types of coal. The lignite is an abundant sedimentary rock and it is found all over the world, unfortunately it is not of great usage.

ki77a [65]

Answer:

b.Venus

Explanation:

Like earth, venus does not have any major faults or folds or rift valleys ridges on its surface thus it does not have any global tectonic or plates of rock in rotation.

Being a terrestrial planet, the seismic data collected from the moment of inertia and possible due to the planet plates are too rigid to move but the phases of volcanoes have been found in the craters in addition mountains, and valleys are commonly found on rocky lands points out to some degree of tectonics present under the planet.

Also, the size and structure of the plan tell about its core, mantle and crustal zones. Also, venus is supported to have a magnetic field not as strong as the earth which is induced by the ionosphere and Solar Winds.

Plato found not only answers but also a method for humans everywhere to work out answers without needing to rely on memorizing t

Ghella [55]

Answer: Plato is an author of "dialogues" (The Republic, Laws etc etc.) where the main character is Socrates. Socrates is a philosopher who uses a special kind of dialogue (so-called dialectic dialogue or dialectic method) which leads him to the truth. In other words he follows LOGOS who leads him to uncovering the Truth.

Explanation: Greek word ALETHEIA means "disclosure" and "truth" at the same time. It means that truth is always hidden. Much older Greek philosopher (pre-Socratic) Heraclitus had a dictum: "Truth likes to hide"....it seems that Socrates/Plato followed this thesis.
