The planting of cover crops can reduce the effects of wind erosion on topsoil beds.
Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
The answer to the missing blank above would be 'the Mongols'. The Mongols invaded Russia around 1300s, which arose to economic downfall and overall negative effect to Russia. Because of this, the Russian princes convened and fought to drive Mongols out of the country.
The Moon of the Earth has some similarities, but also lot of differences with the other natural satellites in the Solar system.
The Moon is rocky, covered with dust, has lot of craters from asteroids and meteorites. Most of the planets in the solar system are actually gassy, frozen, and the craters tend to be very rare.
Compared to the planet around which it spins, the Earth, the Moon is actually very large, even though it is nowhere as large as some other moons in the Solar System. All the other moons tend to be much smaller in comparison the the planets around which they spin.
The Moon also has very low gravitational pull and very small mass for its size, and the reason for that is still not clear. All the other moons have gravitational pulls and masses that are expected by their size.
Well I do know that both Canada and the US have been working on saving animals and plants that live in the wild. I also know that threw these last 5 years we have been making over 14 natural parks a year in the US alone. Canada making less. Both country's want to save natural landscape and they think the best way to do so is natural parks.
Hope this helps! (:
