Question 16
Explain how soil characteristics impact on soil development.
Worked Solution & Example Answer:Explain how soil characteristics impact on soil development. - Leaving Cert Geography - Question 16 - 2014
Step 1
Identify Aspect 1: Parent Material
Answer
The parent material is the underlying geological material from which soil develops. It affects the mineral content and texture of the soil. For example, soils that develop from granite are generally more acidic with low nutrient levels compared to those from limestone, which tends to be more alkaline and nutrient-rich.
Step 2
Identify Aspect 2: Climate
Answer
Climate significantly influences soil development through temperature and moisture levels. Areas with high rainfall can lead to leaching of nutrients, resulting in more acidic soils, whereas arid regions may lead to the accumulation of salts and less fertile soils. These climatic conditions shape the processes of weathering and organic matter decomposition.
Step 3
Identify Aspect 3: Organisms
Answer
Living organisms, such as plants, animals, and microbes, play a crucial role in soil formation. They contribute organic matter, promote nutrient cycling, and enhance soil structure. For instance, earthworms aerate the soil and improve its fertility by breaking down organic material, which positively impacts soil development.
