Do igneous rocks usually contain fossils?

Igneous rocks are formed from cooling and solidifying of molten rock, so they usually do not contain fossils. This is because fossils are typically found in sedimentary rocks, which form from the accumulation of sediment and organic materials, preserving the remains of plants and animals.


Which property of chalk is responsible for absorption of water in it?

The porous nature of chalk, with its many small open spaces, is responsible for its ability to absorb water. Water is drawn into these tiny pores through capillary action, allowing the chalk to retain moisture.


When written in wet chalk first it is not visible but later it is visible why?

Some of the chalk is dissolved into the water and so when you write on a board the chalk can not easily be seen. The water then evaporates leaving only chalk behind therefore becoming visible.


Why not use igneous rocks with relative dating?

Igneous rocks are difficult to date using relative dating because they do not contain fossils. Relative dating relies on the presence of index fossils to establish the age of rock layers, and since igneous rocks form from molten magma that solidifies quickly, they do not typically contain fossils. Additionally, igneous rocks are usually intrusive or extrusive, making it harder to determine their relative ages based on their position within rock layers.


Can fossils be stored in amber?

Are the white cliffs of dover make from fossils or is the lime made from a chemical reaction?

The chalk that forms the White Cliffs of Dover is primarily made up of calcium carbonate from the remains of microscopic marine organisms which lived millions of years ago. Over time, these remains accumulated on the sea floor and were compressed into chalk through geological processes. So, the cliffs are mainly formed from fossils.


Is chalk enviromentally friendly?

Chalk itself is a naturally occurring mineral, so it is generally considered environmentally friendly. However, some commercial chalk products may contain additives or binders that could be harmful to the environment. It's best to look for eco-friendly and non-toxic options when choosing chalk.
