Topography influences species distribution by creating different habitats and environmental conditions such as temperature, moisture, and elevation that can affect where species can survive and thrive. For example, mountains may create barriers that separate species into different habitats or they may influence the distribution of plant species based on elevation gradients. Additionally, topography can affect the movement of species by altering connectivity between habitats.
Yes emotions can affect physical health in many cases. They affect brain, which affects the physical health of person.
