Give an example of how a biome is an open system from the point of view of the biosphere, atmosphere, lithosphere, and hydrosphe
Karolina [17]

Given what we know, we can confirm that the biome is in fact an open system due to the interactions between the biosphere, atmosphere, lithosphere, and hydrosphere.

<h3>What is the biome?</h3>
  • The biome is the collection of air, soil, water, and all the organisms that reside within these ecosystems.
  • In order to describe an open system, we say that the system must have external interactions.
  • A biome is an open system because it has both internal and external interactions, such as with asteroids in space.
  • The internal interactions include the ones between the<em><u> biosphere, atmosphere, lithosphere, and hydrosphere.</u></em>
  • A prime example is the movement of water through each of the spheres.

Therefore, since each part of the biome interacts with each other as well as with external sources such as space, we can confirm that it complies with the definition of an open system.

How would you describe the relationship that gravity has with mass and distance.
PSYCHO15rus [73]

Answer:

Mass does not affect gravity and distance has an indirect relationship.

Explanation:

The equation for gravity is, g = \frac{GM}{R^{2} }

where, G = gravitational constant

             M = mass of the planet

             R = distance between the bodies (object and center of planet)

so, gravity depends on the mass of planet,  not on mass of object

 and is inversely proportional to sqaure of distance.
