Answer: Debate and discussions on climate change are very important among scientists.
Explanation: Many scientific opinions have expressed in the form synthesis reports, by scientific bodies both national and international standing, and also by debate and surveys of opinion among climate scientists. The aim is to mitigate against climate change and creating awareness of the adverse effect on our enivornment.
Universities, scientists and laboratories contribute their quota to the overall scientific opinion through peer-reviewed publications, and the areas of collective agreement and relative certainty are summarised in respected reports and surveys carried out.
Answer:
Density is one of the most factors that play a key role in plate tectonic activities. Some of the ways in which density is important in the field of plate tectonics are as follows-
- The convergent plate boundaries are responsible for the creation of a subduction zone, where the high-density lithospheric plate subducts below the less dense one. It is because the heavier plate is comprised of heavy minerals thereby forming heavier rocks as a result of which its density increases. Due to these differences in density, there occurs a subduction zone.
- The divergent plate boundary forms where two plates move away from one another. This type of plate motion is responsible for the eruption of magma on the seafloor. As the plates diverge, the lithosphere becomes eventually thin, and with more progressive spreading, the magma comes out to the seafloor. This is because the hot magma is less dense, and forms convection cells as they rise upward. This is how the density helps in the upwelling of magma at the mid-oceanic ridge in a divergent plate boundary.
- When there collide two plates of equal densities, then it gives rise to the formation of huge mountains, because neither of them is heavy to get sink. So it uplifts the crust, forming a sandwich-type pattern.
<span>The resource curse, also known as the paradox of plenty, refers to the paradox
that countries with an abundance of natural resources (like fossil
fuels and certain minerals), tend to have less economic growth, less
democracy, and worse development outcomes than countries with fewer
natural resources.</span>
