Science assignment 20 will give brainliest for first due in 30 ! the snowflake starts as part of the cryosphere because it is frozen. as it passes through the atmosphere, let’s assume that it melts and becomes part of the hydrosphere. when it falls to the ground as rain, it will be filtered through the ground. the ground is part of the geosphere. it may end up in a lake where it is consumed by an animal. now it is part of the animal, so it is part of the biosphere. this is just one example of how all the systems interact. let’s go back to our bear on the introduction page. how do you think he fits into and interacts with these systems? write a description of how our bear interacts with each of the systems.

The snowflake starts as part of the cryosphere because it is frozen. As it passes through the atmosphere, let's assume that it melts and becomes part of the hydrosphere. When it falls to the ground as rain, it will be filtered through the ground. The ground is part of the geosphere.Groundwater is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water.Seafood effects the hydrosphere, biosphere, and geosphere. Seafood live in the earth's oceans and waters which directly affect the hydrosphere. They also are living organisms and are food to many other organisms affecting the biosphere. Finally, organisms eat the seafood and deposit it into the geosphereBlack bears are important in ecosystems because of their effects on populations of insects and fruits. They help to disperse the seeds of the plants they eat and consume large numbers of colonial insects and moth larvae. They sometimes take small and large mammals as prey, such as rabbits and deer.

Here you go hope I helped.

in addition to spreading humanist ideas, erasmus has contributed to criticism of corruption in the church.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
