Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Materials from the land's surface can move through the soil and end up in the groundwater. That is why pollution can contaminate an aquifer.
hope this helps:)
<span>Factors that contribute to warming include
1. Carbon dioxide (CO2) from fossils fuel combustion.
2. Parts of earth's surface which have low reflectivity ( low albedo).
3. Tropospheric Ozone (O3).
4. Black carbon aerosols and soot particles.
5. methane (CH4) from decomposition and feedlots.
6. Nitrogen oxides (N2O) from denitrification and fossil fuel combustion.
Factors that contribute to cooling include;
1. Condenses water vapor (Cloud albedo).
2. Parts of earth's surface with high reflectivity (high albedo).</span>
Answer:
Option C, ave destroyed much of the Arctic's fragile coastal ecosystem due to increased foraging.
Explanation:
Snow goose extensively involve in foraging activities in the small and concentrated areas. They spent large part of their day in foraging for instance female spends half of their day in foraging during spring and three fourth of their time before developing nest. Snow goose mainly feed on plants, underground roots and stems such as tubers, agricultural and aquatic plants. They destroy the habitat during winter foraging activities and make environment unsustainable
Hence, option C is correct
