Soil erodes naturally, but human activities can greatly speed the rate of soil erosion, leading to diverse ecological effects an

igor_vitrenko [27]

Answer:

Methods of soil conservation are listed below.

Explanation:

The major sources of soil erosion include water,wind and tillage. In order to mitigate or prevent soil erosion, some of the following techniques can be implemented:

Contour Farming: Planting in row patterns that run level around a hill — as opposed to the up and down the slope pattern.This reduces runoffs and consequently water erosion.
Crop Rotation: This involves planting crops with high residue (e.g corn, small grains, e.t.c) in rotation,as the layer of residue would protect the topsoil.
Built in structural diversion : Used often for gully control, to regulate flow of water away from the field and through designated desired paths.
Conservation Tillage: This involves methods such as no-till planting, strip rotary tillage, etc, which do not allow the soil surface to be smooth and bare, but instead covered with crop residue that protects the soil from eroding forces.

Describe the energetics of covalent and ionic bond formation and breakage?

Luda [366]

Answer:

The strength of a covalent bond is measured by its bond dissociation energy, that is, the amount of energy required to break that particular bond in a mole of molecules. The enthalpy of a reaction can be estimated based on the energy input required to break bonds and the energy released when new bonds are formed.

How is 6.3 written in scientific notation?

Leokris [45]

6.3 × $10^0$
In scientific notation, the numerical value without the exponent of 10 must be within the range from 1 to just below 10 (for example, 9.99...). In this case, 6.3 is already within this range, so we just have to multiply it by 1. To get a multiplier of 1 using base 10, we would have to raise 10 to the zeroth power.
