Select the tool that is called the beaker.

Answers

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:

In this activity, you will write a description of the terrarium model you created to represent the different systems (spheres) of Earth. Make sure to include the words geosphere, biosphere, hydrosphere, and atmosphere in your description.

Answers

Answer:

Below

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.
