Coal is the rock that most fossils are found
Answer:
A. True
Explanation:
Although convection in the asthenosphere is widely accepted as the cause of plate movements, it may be that the weight of down-going lithosphere in subduction zones pulls the trailing plate behind it. This is true because plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move, It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down.
The greenhouse gases<span> absorb some of this energy and radiate much of it back towards the surface whilst the rest is radiated out to space. This plays an </span>important<span>role in keeping the </span>Earth's<span> surface warm and able to sustain </span>life<span>.</span>
Based on cartographic material from three time periods during the nineteenth and twentieth centuries, the impact of river capture, which started in the middle of the nineteenth century, on transformations of the watershed and hydrographic network of two Lithuanian rivers, Ula and Katra, is analysed. It has been determined that river capture conditioned marked transformations of water supply and distribution. As a result of the capture, the area of Ula catchment has increased by 62% and its mean discharge by 63%, whereas the area of Katra catchment decreased by 23% and its mean discharge by 27%. The total area of the five largest lakes in the recent Ula catchment has been reduced by 95%. The transformations of water resources in the Ula catchment since the first half of the nineteenth century are the following: Ula runoff volume has increased almost by 100 million m3/yr whereas the water volume of lakes has been reduced by almost 30 million m3.
river ecosystems support a disproportionately large fraction of its biodiversity, while acting also as significant corridors for the movement of plants, animals and nutrients
