Climate, soil, and topography.

Climate, water, and soil.

Climate, temperature, and water.

Climate, altitude, and water.

Climate determines the temperature and precipitation of a region, which in turn affects the types of plants and animals that can live there. Soil determines the nutrients that are available to plants, which in turn affects the types of plants that can grow there. Topography determines the elevation and slope of a region, which in turn affects the climate and the types of plants and animals that can live there.
