Tectonic is the study of the earth's crust. Tectonics is concerned with the processes which control the structure and properties of the Earth's crust, and its evolution through time. It was considered that earth was made up of tectonic plates. Tectonics also provides a framework to understand the earthquake and volcanic belts which directly affect much of the global population. Tectonic studies are important for understanding erosion patterns in geomorphology and search for petroleum and metallic ores. 

Mulching refers to covering of harvested field with plant litter or polythene of low density, in order to decrease run off, prevent growth of weeds and retention of water.

• Pedology is the study of soils in their natural environment. It is one of two main branches of soil science.
  
• Physiology is the branch of biology that deals with the normal functions and processes of living organisms and their parts.
• Kinesiology is the scientific study of human or non-human body movement. Kinesiology addresses the physiological, biomechanical, and psychological dynamic principles and mechanisms of movement.
  
• Limnology is the study of the biological, chemical, and physical features of lakes and other bodies of fresh water.

Soil is the uppermost layer of the Earth's crust that supports plant life and provides essential nutrients, water, and anchorage for organisms.

Pedology is the study of soils in their natural environment. It is one of two main branches of soil science, the other being edaphology. Pedology deals with pedogenesis, soil morphology, and soil classification, while edaphology studies the way soils influence plants, fungi, and other living things. The quantitative branch of pedology is called pedometrics. Hence, pedology is the science of soil.

(a) Soil; because man and animals are biotic factors and temperature is climatic factor.

Edaphology is concerned with the influence of soils on living things, particularly plants. It includes the study of how soil influences humankind's use of land for plant growth as well as man's overall use of the land. It is one of two main divisions of soil science, the other being pedology. Hence, edaphology is the study of soils.

Sheet erosion is defined as the uniform removal of a thin layer of soil from the land surface by runoff water. Unlike rill or gully erosion, it does not create distinct channels.

Option A is incorrectly matched - Therophytes are annual plants with surviving buds above soil, not 'well above'. Cryptophytes have buds underground, Hemicryptophytes have buds on soil surface, and Chamaephytes have buds at ground level.

Top soil is the topmost and outermost layer of the soil, which is usually 2 inches to 8 inches layer. It is generally dark in colour due to humus, i.e., partially decayed organic matter, soil particles and living organisms as soil bacteria etc.
