GROUNDWATER is the largest source of freshwater on earth.
One resource that I would save would be air. Air pollution is a big problem nowadays because it has effects on human health, can damage crops in a various ways, can cause global warming, climate change, and much more. we can reduce air population by buying vehicles that have greater fuel efficiency, turning off lights when they’re not in use, buying fewer things that are manufactured using fossil fuels, recycle, and try to use eco-friendly products.
It is impossible to build a drainage system on the outside of the Sao Francisco river as buildings are built on the outside of the foundation.
The Subarnarekha is developing a small drainage system.
The Amazon basin is the largest drainage basin in the world.
The Urugay drainage system includes the greater part of southeastern Brazil, Paraguay, southeastern Bolivia and northern Argentina
So i would suggest putting the Amazon as it is the most common known and largest. Remember to use geographical terms!
1. a. Lithosphere
If we divide the Earth into layers by their composition, then there are three of them, the crust, mantle, and core. The crust is the thinnest layer, being on the top, and being solid. The mantle is the second layer, lying between the crust and the core. It is a layer where the temperature and pressure are higher, and the rocks are hot and slow-moving. The core is the bottom layer, in the center of the planet. It is the hottest and has the highest pressure, being the densest of the layers and is composed mostly of iron and in lesser percentage of nickel.
2. b. Crust
The Earth is divided into several layers depending on the layers being solid or liquid. There are five different physical layers, lithosphere, asthenosphere, mesosphere, outer core and inner core. The lithosphere and the inner core are the two layers that are solid, thus the layer on top and the layer in the center. The asthenosphere, mesosphere, and outer core are all liquid, though it is a different degree of liquidity, and it is these three layers where the convection currents occur and cause the magnetic field of the Earth, as well as the tectonic movements.
Valuable resources I think
