<u>Full question:</u>
Which of the following is/are characteristic of the earth but not the moon? A. Molten core B. Plate tectonics C. Asteroid impacts D. Volcanoes
<u>Answer:</u>
Plate tectonics is characteristic of the earth but not the moon
<u>Explanation:</u>
Tectonic plate movements in Earth are forced by convection in the mantle-the hard mantle transits at rates of a some centimeters a year. The Moon’s mantle, too cool to travel easily, has no convection and no moving tectonic plate motions. More uncommon movements inside the Moon indicate fewer quakes. The few moonquakes that do happen are made fundamentally by gravitational tugs by Earth and Sun ).
The quantity and intensity (magnitude) of moonquakes is much less than the quantity and consequence of earthquakes. The feasible reason of this discrepancy is the Moon's smaller size and cooler interior. Earth is hot and active, manifested most dramatically in plate tectonics. The secret of plate tectonics is that the Earth has gaps between the continents, and so they can move around like a sliding block puzzle.
Cos they dont have vascular structure that can defeat gravity and transport water and minerals
C
Explanation:
The only hydrocarbon from the given options is molecule C.
The compound is an aromatic hydrocarbon.
- Hydrocarbons are compound composed of hydrogen and carbon only .
- A hydrocarbon is mostly made up of two atoms that are covalently bonded to one another.
- The major source of hydrocarbons is crude oil or petroleum, natural gas and coal.
- There are many known hydrocarbons.
- Most hydrocarbons burn in excess air to produce carbon dioxide and water.
- The reaction is exothermic.
- Only option C contains Hydrogen and Carbon.

You would need more than natural phenomena for a scientific theory because a theory is a proposed explanation whose status is still conjectural and subject to experimentation, in contrast to well-established propositions that are regarded as reporting matters of actual fact.
The answer is B. 1870 as it was made in 1869
