I think a good addition to a collection of writing instruments that were unique to the twentieth century would be pens and pencils like we have now because back then they dipped feathers in ink and then wrote with them. They were very special because people wrote there feeling and grocery list and drew thing as art. And maybe more to add on would be paint brushes to make beautiful art like they did back then. I hope this helped u and that all your questions are answered.

What can I put labels if information for a project of the Earth's layers

ratelena [41]

Answer:

the outside layer, mantle, inner core and core.

Explanation:

the outside rock layer is a hard outer crust that is relatively thin compared to the rest of the layers. When this layer cracks it can cause volcanic eruptions because the hot magma has built up a lot of pressure so it can force itself through the gap/crack. The mantle is the layers just under the crust. A lot of pressure is built up here as it has a thinner cooler layer above it and a hotter liquid/ hotter rocks just below it. The inner core. This is very hot as it can reach a temperature of around 6,000°c. this is a liquid layer just before the solid inner core of the earth. The core. This is the very centre of the earth and therefor the hottest. This solid centre has a rough minimum of 15,000°F and can roughly get as hot as the sun, scientists have proven that fact. I hope this helped a little with your issue :)
