Answer:
Which species?
Explanation:
If you are talking about dinosaurs and their relatives, then there are many theories. One is a flood wiped them out, which is what Christians believe. Scientists also think that a meteor, volcano eruption, or sudden change of climate could have caused the extinction.
Answer:
D. Overcast skies with strong winds.
Explanation:
clouds, high winds, and precipitation occurs if there is low air pressure is present. A low air pressure areas or regions is also known as cyclogenesis because when the intensity of low air pressure occurs, there is high chances of formation of storms or hurricanes in that region. A low air pressure system refers to a large mass of air that rises due to warmer land or water.
Developing Nations currently produce about 2600 kcal of food per person per day. The growth in food consumption around the world has been accompanied by a significant structural changes and a shift in the diet away from the staple foods such as roots and tubers towards more livestock products and vegetable oils.
Answer:
Renewable Energy Resources.
Explanation:
Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.
Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.
Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.
Answer
Lower Mantle-under high pressure and nearly solid.
Lithosphere-contains the crust
Core-creates the Earth’s magnetic field
Asthenosphere-most deformable layer.
Explanation
The mantle is located below the crust and it occupies the largest volume of the Earth’s volume. The mantle behaves like a plastic and at high pressures and temperatures the rocks in the mantle deform
The lithosphere is the outer shell that contains the crust and upper mantle. The lithosphere is divided into the oceanic layer and the continental layer. It is bounded by the atmosphere and the Asthenosphere.
