Answer: The earth receives a certain amount of Insolation (short waves) and gives back heat into space by terrestrial radiation (longwave radiation). Through this inflow and outflow of heat, the earth maintains a constant temperature and this phenomenon is referred to as the heat budget of the earth. A heat budget is a perfect balance between incoming heat absorbed by the earth and outgoing heat escaping it in the form of radiation. Heat budget is important because it explains, why the earth neither warms up nor cools down despite the huge transfer of heat that takes place.
Explanation:
Due to sea level rise, increase in inundations, and storm surge flooding, shoreline erosion will be prominent. This will affect the people living in the coastal and the coastal ecosystems like salt marshes. Wildfire and insect outbreaks have been increasing and are likely to intensify. Increased risk of deaths due to heat waves, water-borne diseases, and degraded water quality, respiratory illness, and vector-borne infectious diseases. Due to diminishing snowfields, the availability of water has become a major issue. This will add to the pressure on the availability of the groundwater. Apart from the extreme events, climate change impacts in urban centres will be in the form of urban heat islands, air and water pollution, ageing infrastructure, water quality and supply challenges, along with immigration and population growth, and an ageing population. This will increase the stress on natural resources, and lead to their over-exploitation and exhaustion.<span />
Answer:
All issues are related to each other.
Explanation:
- Environmental issues like Biodiversity and genetic modification related to the alterations in the genetic makeup of species richness on earth. Biodiversity today faces a challenging situation where the loss of habitats and modification of the environment takes place that leads the species to adapt fast to the next environment. Either by natural selection or genetic drift.
- Deforestation is the complete removal or clearance of forest land by man for construction or development purposes, which leads to the development of desertic conditions over the natural landscape as trees hold the soil by roots from getting blown away.
- Global warming and ozone layer depletion, both causes of man-made anthropogenic wastes and harmful gases that warm and destroy the upper atmosphere and raise the temperature of the world's oceans and water levels.
Based on ages of the oldest rocks in the North and South Atlantic, describe how and when the Atlantic Ocean formed, and how its shape has changed through time.
Hope this helped, have a great day! :D
