Question

respond to the following based on your reading. question 1 which processes are responsible for uneven distribution of metals in earths crust? how do these processes cause metals to be distributed? question 2 what is the biggest problem with desalination?

Explanation:

For Question 1: Tectonic activity like volcanic eruptions and plate - movements can concentrate metals in certain areas. Magmatic processes can bring metals from the Earth's interior to the crust in specific regions. Weathering and erosion can disperse metals unevenly.
For Question 2: The biggest problem with desalination is its high energy consumption, which makes it expensive and can have environmental impacts due to the energy sources used.

Answer:

Question 1: Tectonic, magmatic, weathering and erosion processes cause uneven metal distribution by concentrating or dispersing metals.
Question 2: High energy - consumption and associated costs and environmental impacts.
