6.
compared to the time in earth's history before humans appeared, rates of soil erosion are

about the same
faster
slower
more unpredictable

7.
the process responsible for moving material downslope under the influence of gravity is called

erosion
weathering
mass movement
soil formation

8.
why can the removal of vegetation trigger mass movements?

the soil loses nutrients and begins to crumble.
the plant roots bind the soil and regolith together.
the shaking triggers mass movements.

Here are the answers of the given questions above.
6. Compared to the time in Earth's history before humans appeared, rates of soil erosion are FASTER. This is because of the activities of humans such as farming, logging and construction; and this contributed to the reason why soils are eroding faster.
7. The process responsible for moving material downslope under the influence of gravity is called MASS MOVEMENT.
8.The answer would be the second option. The removal of vegetation would trigger mass movements because the plant roots bind the soil and regolith together.

Science27 of the most iconic, jaw-dropping photos of the earth and the moon from spacedave mosher  oct 1, 2018, 11: 13 am etnasa/flickrapollo 11 astronauts took this photo of earth on july 20, 1969.from the ground, earth looks like a boundless fertile plain that beckons to be explored and exploited.but astronauts would beg -  and even plead  - to differ."you realize that people often say, 'i hope to go to heaven when i die,'" jim lovell, an astronaut who flew on the apollo 8 and apollo 13 missions to the moon, previously  told business insider. "in reality, if you think about it, you go to heaven when you're born."lovell has seen first-hand that we live on a tiny rock hopelessly lost in the void. he's also quick to tell you it's the only one we've got - a  fragile spaceship  for more than 7 billion people: "you arrive on a planet that has the proper mass, has the gravity to contain water and an atmosphere, which are the very essentials for life. and you arrive on this planet that's orbiting a star just at the right distance - not too far to be too cold, or too close to be too hot - and just at the right distance to absorb that star's energy and then, with that energy, cause life to evolve here in the first place. in reality, you know, god has really given us a stage, just looking at where we were around the moon, a stage on which we perform. and how that play turns out is up to us, i guess."humanity has recorded photos of earth from hundreds, thousands, millions, and even billions of miles away, some of them taken by lovell himself.these images not only scientists study our dynamic world, but also understand how a habitable planet looks from afar, which aids the search for  more worlds. most importantly, however, the images underscore our peculiar existence on  a mote of cosmic dust.take a moment to ponder 27 of the most arresting images of earth that humankind has ever captured from space.a
