Answer:

The fourth one is the beaker.

Explanation:

Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Laboratory Burners are sources of heat.

The beaker is typically made of glass or plastic and has a cylindrical shape with a flat bottom and a spout for easy pouring. Therefore image 4 is correct.

The beaker is a simple and versatile laboratory tool used for holding, mixing, and measuring liquid substances.

Beakers come in various sizes, ranging from small to large capacities, and are marked with volume measurements for accurate liquid volume readings.

They are commonly used in chemistry, biology, and other scientific disciplines for tasks such as preparing solutions, conducting experiments, and holding samples.

The beaker's wide mouth and durable design make it a fundamental and indispensable tool in any laboratory setting.

Therefore image 4 is correct.

Explanation:

The geosphere refers to the land of the Earth.

The biosphere refers to all the living things on Earth.

The hydrosphere refers to all of the water in the Earth.

The atmosphere refers to the air on Earth.

To create a terrarium model, you could start by placing rocks all throughout the bottom of it. Pile up more on one side to create a hill. This represents the geosphere. Then, fill some of it with water. Make sure some of the rocks of that hill you made are still above the water, however. This represents the hydrosphere. Next, add a little plant or even a toy animal in to represent the biosphere. Finally, the remaining space represents the atmosphere, as humans can't see it so it's just clear.

The terrarium is a small, enclosed ecosystem that beautifully showcases the geosphere, biosphere, hydrosphere, and atmosphere in miniature form.

The geosphere is represented by the solid base of the terrarium, which mimics the Earth's crust and surface. Various rocks, pebbles, and soil are incorporated to depict the diverse landscapes found in the geosphere, such as mountains, valleys, and plains.

For the biosphere, added a selection of plants and small organisms. These living elements bring the terrarium to life, representing the complex interactions between flora and fauna found in the biosphere. Plants play a crucial role in converting carbon dioxide to oxygen through photosynthesis, simulating the vital connection between the biosphere and the atmosphere.

Next, the hydrosphere was depicted by a small, serene water feature within the terrarium. This mini aquatic environment captures the essence of Earth's oceans, rivers, and lakes, showcasing the interconnectedness of the hydrosphere with other systems. The water's presence also influences the microclimate, creating a more dynamic terrarium ecosystem.

Finally, the atmosphere is subtly indicated by the transparent walls of the terrarium, enclosing and safeguarding the entire model. This clear boundary represents the thin layer of gases surrounding Earth, providing protection and the right conditions for life to thrive within the terrarium's microcosm.

Thus, the combination of these different elements in the terrarium creates a harmonious representation of Earth's interconnected systems.

Explanation:

colour is the most indicater in the chemistry

The geocentric model is a cosmological model that places the Earth at the center of the universe. This model was the prevailing view of the cosmos for centuries, and it was supported by the apparent daily movement of the Sun, Moon, and stars across the sky.

However, the geocentric model was eventually disproven by the heliocentric model, which places the Sun at the center of the universe.

The geocentric model was first proposed by the ancient Greek philosopher Ptolemy in the 2nd century AD. Ptolemy's model was based on the observation that the Sun, Moon, and stars all appear to move across the sky in a regular and predictable way.

He also observed that the planets appear to move in a looping pattern, which he explained by proposing that they orbit the Earth in a series of nested spheres.

Ptolemy's model was very successful in explaining the apparent motions of the Sun, Moon, and stars. However, it was not without its flaws.

For example, the model required the introduction of a number of epicycles, which were small circles that were attached to the larger circles that the planets orbited. These epicycles were necessary to explain the looping motion of the planets.

The geocentric model was eventually disproven by the heliocentric model, which was proposed by the Polish astronomer Nicolaus Copernicus in the 16th century.

Copernicus's model was based on the observation that the planets all orbit the Sun in the same direction, and that they all have nearly circular orbits. He also observed that the Earth rotates on its axis once every day and that it orbits the Sun once every year.
