Vitamin D, Iron and Folic Acid
During pregnancy, the three key vitamins and minerals that often undergo the greatest percentage of increase are folic acid (folate), iron, and calcium. These nutrients are crucial for the development of the baby and supporting the increased demands on the mother's body during pregnancy. It is important for pregnant women to ensure they are getting adequate amounts of these nutrients through their diet or supplements.
The greatest percentage of soil is typically made up of mineral particles. These minerals come from the weathering of rocks and minerals, contributing to the physical properties of soil.
If the percentage of felsic minerals in a rock increases, the rock will become lighter in color and less dense. Felsic minerals are rich in silica and aluminum, so the rock may also become more viscous when melted. Additionally, the rock's melting temperature may decrease.
An increase in temperature and precipitation would most likely cause the greatest increase in chemical weathering of local bedrock. Warmer temperatures can enhance chemical reactions, while higher rainfall can accelerate the dissolution of minerals in the bedrock, leading to increased weathering.
Calcium
The two elements that make up the greatest percentage of Earth's crust by mass are oxygen and silicon. Together, they account for about 75% of the crust, with oxygen making up approximately 46% and silicon about 28%. These elements primarily combine to form silicate minerals, which are the most abundant in the Earth's crust.

When it rains, this helps wash minerals into the ocean from the land, which will add more minerals into an area of ocean water. Also, the formation of sea ice can also increase the amount of minerals.
