Answer:

The correct option is: d. light isotopes move faster than heavy isotopes and thus are more readily evaporated

Explanation:

Evaporation is the process by which water present in liquid state changes into water vapor.

Since, oxygen has two isotopes: ¹⁶O (light isotope) and ¹⁸O (heavy isotope). Therefore, water molecule that consists of ¹⁶O is known as light water (H₂¹⁶O). Whereas, water molecule that consists of ¹⁸O is known as heavy water(H₂¹⁸O).

Since evaporation of heavier water molecules (H₂¹⁸O) is difficult than evaporation of light water molecules (H₂¹⁶O).

<u>Therefore, the water vapor formed by evaporation is rich in light water (H₂¹⁶O).</u>

Identify two ways to reduce wind erosion and how do they work? Please write in complete sentences with correct capitalization, g
enot [183]

Answer:

Two ways to reduce wind erosion are: Covering the Surface of the Soil and Making use of Shelterbelts.

Explanation:

Wind erosion is a natural activity where a soil is moved from one place to another mainly because of the wind power. If so happens that a strong blow of wind comes and takes away with it the volume of soil particles and transfers it to other place creating dust storms.

Wind erosion can be reduced by Covering the Surface of the Soil. This can be done by growing vegetation which will protect the soil by the keeping the wind off the soil surface. Another way to reduce wind erosion is by making use of Field Shelterbelts. Shelterbelts are the best way because it not only reduce the wind erosion but at the same time it also conserve the soil moisture. Shelterbelts is a planting method where fields are planted in rows of varied crops.

Explanation:

The two rock can be confused with each other as both appear rough to touch and both are found in shades of black & brown and dark themes, also shades of grey sometimes prevail. They do have similarities in the hardness on some scale as Quartzite is hard while basalt is intermediate in hardness.

Major difference between them are:

They differ in the mode of formation as Quartzite is Metamorphic Rock while Basalt is the Igneous rock formed from the Volcanoes. Quartzite have medium grain size and foliated, granular structure while Basalt is fine grained and glassy in texture.
