What is not a property of water that helps make water essential for life on Earth?
Anna007 [38]
So the the main forces that keep the water on the surface of the planet are to do with plate tectonics. If the plates were to stop moving, the water probably would eventually be absorbed into the interior, although this process would take a very long time indeed.

The line tic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s is
tangare [24]

Answer: 25 joules

Explanation:

Recall that kinetic energy is the energy possessed by a moving object.

So, kinetic energy = 1/2 X Mass X Velocity^2

Mass = 0.5kg

Velocity = 10m/s^2

= 1/2 x 0.5kg x 10^2

= 0.5 x 0.5 x 100

= 25 Joules

Thus, the kinetic energy of the moving ball is 25 joules

Species richness increases Select one: a. as we increase in altitude in equatorial mountains. b. as community size decreases. c.
olga55 [171]

Answer:

D) as we travel southward from the North Pole.

Explanation:

Species richness is the number of different species in a particular community. If we found 30 species in one community, and 300 species in another, the second community would have much higher species richness than the first.

Communities with the highest species richness tend to be found in areas near the equator, which have lots of solar energy (supporting high primary productivity), warm temperatures, large amounts of rainfall, and little seasonal change. Communities with the lowest species richness lie near the poles, which get less solar energy and are colder, drier, and less amenable to life. This pattern is illustrated below for mammalian species richness (species richness calculated only for mammal species, not for all species). Many other factors in addition to latitude can also affect a community's species-richness.

devlian [24]
Install an electrostatic precipitator (ESP) component, which is a particle control system that helps remove particles from a smokestack by using electrical charges. According to the U.S. Environmental Protection Agency, an ESP can remove small particles with up to 99 percent efficiency.
