Mantle convection is a type of current that raises from the mantle plumes with lava or magma and its rising lava reaches the earth through volcanic eruption and further through the burning of plates inside the mantel, it is directly connected with at of the plates on earth as its due to this effect that the ring of fire is dotted by earthquakes of all types. The Hawaiian volcanoes are on this line also thus are highly explosive and viscous lava flowing from vents, the zone of most active volcanoes.
The answer is going to be c.
In rain storms methane gases into carbon, as it falls it turns into pieces of graphite and then into diamonds.
The weathering of rocks in Zion and Bryce canyons takes place by both physical and chemical weathering.
<h3>What is weathering?</h3>
- Rocks, soils, minerals, wood, and manmade materials all deteriorate due to weathering when they come into touch with water, air gases, and living things.
- The process of weathering's contribution to soil formation is arguably its most significant feature.
- Weathering comes in three flavors: physical, chemical, and biological.
- Weathering can be facilitated by wind, water, ice, plants, gravity, and temperature variations.
- Things become fragmented via weathering. Erosion is the process through which soil or rock fragments move to new sites.
- Different landforms can alter in size, shape, and texture due to weathering and erosion (such as mountains, riverbeds, beaches, etc).

The correct answer is - No.
The changing birthrates, be it becoming lower or higher, will not and can not change the development of the country just by themselves. The development of the countries does depend on the birthrates, but it also depends on the death rates, the conditions for life, the healthcare, the availability of resources for the people.
If the birthrates are very high, we will immediately assume that the country will have a bright future because it has a constantly growing young population which will be increasing the labor force, and that is always good for the development. On the other hand, the living conditions may be terrible int he country, resulting in a very high death rates, with lot of infants and young children dying, as well as a very low life expectancy. That will be terrible for the development of the country as the people will be in terrible physical and psychological condition, thus not being able to contribute a lot for the development as they will not be able to work a lot, nor work properly. This is unfortunately the case in lot of the sub-Saharan African countries.
