Why are stone tools found on their own?
Stone tools are found on their own because they do not decompose and stay as they are.
What is the importance of stone tools in human history?In the broadest definition, a stone tool is any tool that is manufactured totally or mostly of stone.
Some stone tools were used for chopping fruits and roots as well as for cutting flesh and bone, removing bark from trees, and cutting into hides, or animal skins. A few of them served as handles. Some were used to create hunting spears and arrows.
Early human creations, such as stone tools and other artifacts, provide information on how people lived, interacted with their environment, and changed over time. Thousands of archaeological sites have been investigated, excavated, and dated during the last 2.6 million years.

How can the history of Mount Rainier's eruptions help you decide whether hiking around Mount Rainier is safe?
The history of Mount Rainier's eruptions can help you decide whether hiking around Mount Rainier is safe by providing information about the volcano's past activity, eruption patterns, and potential hazards.
The history of Mount Rainier's eruptions provides valuable insights into the volcano's behavior and can help assess the safety of hiking around the area. By studying the volcano's eruption history, scientists and authorities can gather data on the frequency, magnitude, and types of eruptions that have occurred in the past.
This information is crucial for understanding the potential hazards associated with the volcano. For example, if Mount Rainier has a history of frequent and large explosive eruptions, it may indicate a higher level of risk for hikers due to the potential for ashfall, pyroclastic flows, or lahars (volcanic mudflows) that can pose dangers to human life.
Additionally, analyzing the timing and recurrence intervals of past eruptions can help estimate the likelihood of future eruptions. If the volcano has been relatively inactive for an extended period, it may suggest a lower immediate risk for hikers. However, it is essential to consider the potential for future eruptions and monitor any signs of volcanic unrest or changes in activity.
Furthermore, studying the extent and distribution of past volcanic deposits, such as lava flows or ash layers, can help identify areas that are more prone to hazards. This information can be used to establish exclusion zones or restrict access to certain hiking trails that may be closer to potential hazards.
Ultimately, by considering the history of Mount Rainier's eruptions and the associated hazards, authorities can make informed decisions regarding the safety of hiking around the volcano. It is crucial for hikers to stay updated with the latest information from local authorities, volcanic monitoring agencies, and park management to make responsible choices and ensure their safety when exploring the area.

They are decomposers that break down organic wastes and dead organisms into compounds used by plants for photosynthesis.
They are producers that make food by converting water and carbon dioxide into glucose and oxygen, using energy from the Sun.
They are autotrophs that use chemicals as an energy source to produce food when sunlight is not available.
They are heterotrophs that get their energy by consuming plants, herbivores, and other primary consumers.
The following is the best explanation of the role of fungi and slime molds in the rainforest food web is that they are decomposers that break down organic wastes and dead organisms into compounds used by plants for photosynthesis, as presented in the first option.
What is the significance of the decomposers?Decomposers are organisms that break down dead plant and animal matter and convert it into simpler substances that can be recycled as nutrients for the ecosystem and are a critical part of the ecosystem, as they play a vital role in the carbon and nitrogen cycles, help break down organic matter, making it easier for plants to absorb nutrients from the soil and this process helps to maintain the balance of nutrients in an ecosystem and supports the growth of new plants and animals.

A wave has a wavelength, L = 50m, and is traveling in water with a depth of 30m. It is a _________
Group of answer choices
deep water wave
medium water wave
shallow water wave
can't determine
Answer:
The answer to this question is medium water wave
The kind of wave described in the illustration would be a deep water wave.
According to definition, a deep water wave is a wave that occurs at water depths that is more than half the wavelength of the wave.
In this case, the wavelength of the wave is 50 m and the depth of the water is 30 m. Half of the wavelength of the wave would be 25 m.
Thus, the depth of the water is more than half of the wavelength of the wave. This effectively makes the wave a deep water one.

Answer:
As during the civil war, African elephants with tusks were targeted, and the tuskless elephants were left alone. This, in turn, allowed for the tuskless elephant populace to thrive and continuously grow, while the tusked elephants saw a decline as more and more were poached. So, it is only natural that as time progresses, and assuming the circumstances remain constant, that the tusked elephant population will see a negative trend, and inversely the tuskless elephant population will see a positive trend.
