Explanation / Answer

1-true

Meteorites are dense, they will feel heavier than ordinary Earth rocks of a similar size. Recently fallenmeteorites will have fusion crust on the outside

2-true

3- false

Jack Hills, Australia, where rocks were found to contain the oldest known minerals on Earth, a 4.4 billion-year-old zircon. Just three of the very oldest zircons have been found, ones that date back to almost 4.4 billion years ago.

4- true

Banded iron formation or BIF is a chemical sediment, typically thin-bedded or laminated with >15% iron of sedimentary origin. ... Rare earth element distributions in BIF and marine cherts in particular have proven to be useful in distinguishing continental from hydrothermal inputs to the oceans.

5- true

the South Pole, which lies over the continent of Antarctica, there is no land beneath the North Pole but more of a floating Arctic ice sheet that expands during colder months and shrinks to half its size in the summer.

6-true

Meteorites are amongst the oldest items we find on earth. In fact, some are even older than the planetwe live on - and presumably even our solar system

7- false

Photosynthesis is the chemical process that plants use to create food for themselves. ... While the implications of the new finding are still unclear, it's possible that, as carbon dioxide levels rise

8-true

Strombolite provides cohesiveness with respect to family ties and closeness within a group.

9-true

Basalt is a dark-colored, fine-grained, igneous rockcomposed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It has a composition similar to gabbro.

10-true

Trilobites were an extinct marine arthropod that lived during the Paleozoic era.

11- Forever is a long time, though, and even zircons eventually degrade Peridot, one of the shortest-lasting gemstones

12-true

A large proportion of our cells, muscles and tissue is made up of amino acids, meaning they carry out many important bodily functions, such as giving cells their structure.
