Answer:

Closed Systems. The earth system as a whole is a closed system. ... Virtually no mass is exchanged between the Earth system and the rest of the universe (except for an occasional meteorite). However, energy in the form of solar radiation passes from the Sun, through the atmosphere to the surface.

Answer:

The earth is a closed system because only energy is naturally transferred outside the atmosphere.

Explanation:

A closed system is a system in which only energy is transferred with its surroundings. An open system, however, is a system in which both energy and matter can transfer.

How do scientists determine the depth of the ocean?
IgorC [24]

Explanation:

The most common and fastest way of measuring ocean depth uses sound. Ships using technology called sonar, which stands for sound navigation and ranging, can map the topography of the ocean floor.

Several factors have been considered before the construction was started. This includes the wildlife in the area and certain precautions have been made for their benefit and protection.

What is the difference between a hot-water system and a steam-heating system?
Nonamiya [84]

Steam radiators and hot water radiators are very similar, so much so that in many cases they are interchangeable. Many homes have been converted from steam to hot water heating systems (and vice versa) without having to change the actual radiators.

The most obvious difference between the two is that a hot water radiator is always equipped with two connections: hot water goes into the radiator on one side, and the cooled water leaves on the other. Steam radiators can have either one or two connectors: hot steam can enter on one side, and condensed water can leave either through the same pipe or through a pipe on the other side.

While it is certainly best to use a steam radiator for steam and a hot water radiator for water, in some cases a switch between the two will require only a few simple operations.
