Answer:
Evidence of seals and other objects in other regions.
Explanation:
Archaeologists have played a vital role in finding past by excavating for artifacts. The presence of sea-going vessels in the Indus Valley civilization indicates the artifacts that have found different civilizations like Mesopotamia and China. Some of the goods traded like beads, pearls, gold, silver, terracotta pots, turquoise, lapis lazuli, metals, flints, and seashells.
Scholars believe that the Indus Civilization had sea-going vessels due to their advanced knowledge of water engineering, archaeological evidence of intensive seaborne trade between the Indus Valley and Mesopotamia, and the presence of a dockyard and warehouse in the ancient city of Lothal. Indus valley seals found in Mesopotamian cities provide further proof of this maritime trade.
Scholars have deduced that the participants in the Indus Valley Civilization had sea-going vessels based on various factors. Primarily, their sophisticated knowledge of water engineering and the existence of wide city drainage systems suggest a high understanding of hydrodynamics. Their advanced urban planning and unique construction techniques translated to possible skills in making sea-worthy vessels.
Moreover, archaeological evidence shows that intensive trade took place between the Indus Valley and Mesopotamia. Precious stones, marine shells, and other goods from the Indian Ocean were imported, implying sea-transportation. After all, these goods would have had to be transported by sea, over considerable distances.
The presence of a dockyard and warehouse at the ancient city of Lothal near the Indian ocean also suggests the handling and storage of trade goods transported by sea. Artifacts like seals from the Indus Valley found in far-off Mesopotamian cities like Ur attests to this extensive seaborne trade. Thus, the Indus Valley people most likely had sea-going vessels to facilitate this exchange and trade.

The federal government to say state laws are unconstitutional
Answer:
With imperialism, European nations spread their influence across the globe. They brought European culture; language, religion, government, and education systems to many different regions in the world. India is a good example of cultural diffusion.
Environmental catastrophes, either due to human activities or natural disasters, can cause short-term and long-term changes to the Earth's surface, altering ecosystems and weather patterns. These changes could include melting glaciers, rise in sea levels, and changes in seasonal patterns among others.
Yes, environmental catastrophes can indeed cause changes to the Earth’s surface. Different factors, such as human activities, global climate change, and natural disasters, can all contribute to altering the Earth's environment and ecosystems. For example, the excessive use of fossil fuels has led to the depletion of the ozone layer, desertification, topsoil loss, and changes in global weather patterns—some of which may threaten the collapse of certain ecosystems.
Short-term changes might include unseasonal rainfall or changes to the life cycles of insects and animals. Long-term effects, on the other hand, could signify more permanent alterations, such as the melting of glaciers or a rise in sea levels, which could potentially submerge islands situated near sea level and devastate the local ecosystems.
Certain natural disasters, such as volcanic eruptions or earthquakes, can also prompt changes to the Earth's surface. Overall, understanding these potential changes and their consequences is crucial to implementing effective strategies for environmental conservation.

Answer:
The mesosphere is the third and coldest layer of Earth's atmosphere, reaching about 130 degrees below zero. The mesosphere is also where most meteors, or space rocks and metal, burn up before they can crash to the ground. It's like a superhero's force field that protects the Earth! The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere. The coldest temperatures in Earth's atmosphere, about -90° C (-130° F), are found near the top of this layer. Location. Mesosphere : The third layer of the atmosphere. ...
Middle Atmosphere. Mesosphere: Meteors burn in this layer. ...
Transition Region. Each atmosphere layer has a transition region at the point where one ends and the other begins. ...
Explanation:
Helpful variations accumulate in species over time through the process of natural selection. When a species reproduces, individuals with advantageous traits have a higher chance of survival and reproduction, passing those beneficial traits to the next generation.
This results in an increased frequency of advantageous traits within the population. Over many generations, the accumulation of helpful variations can lead to significant adaptations that enhance the species' ability to survive and thrive in its environment.
As environmental conditions change, the process of natural selection continues, continuously shaping the characteristics of the species and driving its evolution over time.
