How do animals affect landforms?

When too many animals live in one place, they tend to eat and trample all the plants. Without the plants to protect the soil, it is much more likely to be eroded by wind and water. Animals cause weathering and erosion on rocky shorelines.

What is fauna in geography?

By definition, fauna is a group of indigenous animals of any geographical region. So, the term flora and fauna was coined by biologists to refer to a collection of plant and animal specifies in a given geographic location.

What is the importance of fauna?

Flora and fauna are very important for human existence. The flora liberates oxygen that is consumed by the fauna for respiratory activities. Fauna, in turn, liberates carbon dioxide consumed by the flora for photosynthesis. Flora and fauna hugely benefit mankind through its medicinal and food offerings.

What are some examples of fauna?

Soil mesofauna
Fauna/Representative species

How do animals affect geography?

They can make footprints and nests. Ali- They can change the geography by wrecking habitats. They might kill beaver who are very important. Lara – Animals like beaver create dams and that can be important if there is too much water in a place.

How do animals and plants cause weathering and erosion?

Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.

Why is conservation of flora and fauna important?

The reasons for conservation of flora and fauna is: 1) To maintain biodiversity – this ensures that the variety of plants and animals are maintained in the environment such that no species are lost. 2)To maintain ecological balance – ecological balance is very important because life is supported by this balance.

What are the factors on which flora and fauna depends?

The important elements are rainfall, temperature, soil, altitude and geographical structure.

What is impact on flora and fauna?

Noisy activities can have negative impacts on fauna, and gases from landfills and incinerators may damage surrounding vegetation. Pollution of watercourses and canals can cause damage to vegetation, fish and fauna.

What is fauna in environmental science?

Fauna is a term which refers to all of the animal life within a specified region, time period, or both. The “flora and fauna” of a certain place is a descriptor of all the life in a region, including both the plant-like organisms and the animal-like organisms.

What does fauna refer to?

Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is flora. Zoologists and paleontologists use fauna to refer to a typical collection of animals found in a specific time or place, e.g. the “Sonoran Desert fauna” or the “Burgess Shale fauna”.

How do animals change landscapes?

Mammalian herbivores have important top-down effects on ecological processes and landscapes by generating vegetation changes through grazing and trampling. For free-ranging herbivores on large landscapes, trampling is an important ecological factor.

How do human activities affect landforms?

Human activities affect landforms by causing erosion (e.g., farming) that reduces surface soil and is carried down rivers to increase river deltas, removing parts of mountains or hills or filling in valleys for , by strip mining, by drilling, etc. Human activities effect landforms by building hills, digging canals, etc.

How does changing land use(agriculture) affect drainage basin systems?

Clearance of trees reduces evapotranspiration, but increases infiltration and surface runoff. 10 How does changing land use (agriculture) affect drainage basin systems? Arable to pastoral: compaction of soil by livestock increases overland flow. Pastoral to arable: ploughing increases infiltration by loosening and aerating the soil. 11

What are the impacts of physical and human factors on drainage?

Impact Of Physical And Human Factors On The Drainage Basin Water Budgets And River Systems Deficits Within The Hydrological System Surpluses Within The Hydrological Cycle Climate Change And The Hydrological Cycle Causes Of Water Insecurity

What happens to rain that falls in a drainage basin?

All of the precipitation (rain or snow) that falls within a drainage basin eventually flows into its stream, unless some of that water is able to cross into an adjacent drainage basin via groundwater flow. An example of a drainage basin is shown in Figure 13.4.
