D. Planets formed from small amounts of debris that were attracted together because of gravity.
A dense cloud of interstellar gas and dust formed our solar system roughly a billion years ago. A solar nebula—a whirling, swirling disk of material—was produced when this dust cloud collapsed. Gravity drew more and more material into the center. The sun was still forming and planets had not yet been created when the solar system was very young. The solar system consisted primarily of gas and dust.

What is mineral ?A mineral or mineral species is, generally speaking, a solid chemical compound that naturally occurs in pure form and has a very well-defined chemical composition as well as a particular crystal structure.
Each crystal structure that makes up a chemical compound that exists naturally as a separate mineral species. As an illustration, silicon dioxide is a component of the same mineral species as quartz and stishovite.
They can be mined and have the potential to be exploited as a source of metal. Manganese, iron ore, and bauxite are examples of metallic minerals, which can be either ferrous or non-ferrous. While ferrous minerals do contain iron, non-ferrous minerals do not.
Thus, option B is correct.

1. What are the different ways tectonic plates move in relation to each other?
2. What landforms could be the result of converging plates? name a location where this occurs.
3. What landforms could be the result of diverging plates? Name a location where this occurs.
4. What major event could occur as the result of transforming plates? Name a location where this can occur.
5. if crust is constantly created at divergent boundaries, why isn't Earth getting larger?
Answer + Explanation:
1. The different ways tectonic plates move in relation to each other are:
convergent (where plates move into one another)
divergent (where plates move apart)
transform (where plates move sideways in relation to each other)
2. Convergent plate boundaries can result in:
earthquakes, volcanoes, and the formation of mountains.
The Himalaya Mountains are the result of convergent plate boundaries.
3. Landforms that are a result of divergent boundaries are rift valleys and mid-oceanic ridges.
Locations where this occurs are: Mid-Atlantic Ridge, Red Sea Rift, Baikal Rift Zone
, East African Rift, East Pacific Rise, Gakkel Ridge, Galapagos Rise, and Explorer Ridge.
4. Transforming plate boundaries results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.
A location where this occurs is: San Andreas Fault in western California
