Geography Water Quiz

If we were to run out of water, it would have a catastrophic impact on all living beings. Without water, humans, animals, and plants would not be able to survive. Water is essential for the functioning of our bodies, and without it, we would not be able to sustain life. Additionally, animals and plants rely on water for their survival as well. Therefore, if we were to run out of water, it would result in the death of everything.

An aquifer refers to underground water that is stored in permeable rock or soil layers. It is a natural underground reservoir that holds and supplies water to wells and springs. Aquifers are typically formed by the accumulation of rainwater or melting snow that seeps through the ground and gets trapped in porous rocks or sediments. This underground water can be accessed for various purposes such as drinking water, irrigation, and industrial use.

An aquifer is a underground layer of permeable rock or sediment that contains water. Limestone, sandstone, and granite are all types of rocks that can be found in aquifers. Therefore, the correct answer is "All of the above" as all three types of rocks can be present in an aquifer.

The correct answer is "Damaged" because the statement indicates that a significant portion (50 to 80%) of the Murray Darling Basin wetlands are in a state of disrepair or deterioration. This suggests that these wetlands have experienced negative impacts and are not in a healthy or beautiful condition. The term "damaged" implies that there may be ecological or environmental issues affecting the wetlands, potentially due to human activities or natural factors.

The correct answer is "Mostly winter". This suggests that K. Victoria experiences the highest amount of rainfall during the winter season compared to other seasons.

Queensland is the correct answer because it is known for having the highest amount of rainfall compared to the other states listed. Queensland experiences a tropical climate in the northern parts, which contributes to higher rainfall levels. The state also has a diverse geography, including coastal areas and mountain ranges, which can further contribute to increased rainfall.

Dams can disrupt the natural flow of water, which can prevent the transportation of nutrients downstream. This can negatively impact the ecosystem and the organisms that rely on those nutrients for survival. Additionally, dams can create barriers for fish, preventing them from migrating and reaching their spawning grounds. This can lead to a decline in fish populations and disrupt the balance of aquatic ecosystems. Therefore, the inability of nutrients to travel is a valid reason why dams may not be good for the environment.

The Great Artesian Basin is estimated to be almost 2 million years old. This is based on geological evidence and the age of the sediments found within the basin. Over time, the basin has accumulated water from rainfall and underground sources, making it one of the largest and deepest underground water reservoirs in the world. Its age is significant as it demonstrates the long-term geological processes that have shaped the landscape and contributed to the formation of this important water resource.

An aquifer might dry out when a bore is extracting water from it. This means that if a bore is continuously removing water from the aquifer without allowing it enough time to recharge, the water level in the aquifer will gradually decrease, eventually leading to its drying out. This can happen regardless of the season or weather conditions, as long as the water extraction continues without proper management or replenishment measures.

One possible reason that not many people live in Queensland could be due to the abundance of water in the region. While water is essential for human survival, an excessive amount of water can lead to challenges such as flooding, waterlogging, and difficulties in infrastructure development. These factors may make it less appealing for people to settle in Queensland, resulting in a lower population density compared to other regions.

Aquifers are underground layers of permeable rock or soil that hold water. They are important sources of water for drinking and irrigation. Since aquifers contain water, they can support various forms of life. Fish, invertebrates, and plants can all live in aquifers, making them diverse ecosystems. Therefore, the correct answer is "Fish, invertebrates, and plants."

The Murray Darling is a river system in Australia, stretching across multiple states. It is one of the longest rivers in the country, measuring approximately 4000 kilometers in length.

Lake Eyre is the correct answer because it is the lowest point in Australia. Located in South Australia, Lake Eyre is a salt lake that sits approximately 15 meters below sea level. It is the largest lake in Australia and is known for its unique ecosystem and occasional flooding events. The other options, Murry River, Cooper River, and Lake Victoria, are not the lowest points in Australia and therefore are not the correct answer.

Carp can make native fish struggle to live because they are invasive species that compete with native fish for resources such as food and habitat. Carp reproduce rapidly and can quickly dominate an ecosystem, leading to a decline in native fish populations. Additionally, carp are known to uproot vegetation and stir up sediment, which can degrade water quality and further impact native fish species.

Algal blooms occur due to a high level of nutrients in the water. When there is an excess of nutrients, such as nitrogen and phosphorus, in the water, it promotes the rapid growth of algae. These nutrients act as fertilizers for the algae, causing them to multiply and form dense populations. As a result, the water becomes green or discolored, and the excessive growth of algae can have detrimental effects on the ecosystem. This includes depleting oxygen levels in the water, leading to the death of aquatic organisms, and disrupting the balance of the ecosystem.

The correct answer is "An ecosystem" because a river is not just a body of water, but also a complex ecosystem that supports a wide variety of plant and animal life. Rivers provide habitat for fish, insects, birds, and many other organisms, and they also play a crucial role in the water cycle and nutrient cycling. Additionally, rivers are often interconnected with other ecosystems such as wetlands and forests, further contributing to their ecological importance.

The Western Plateau is the correct answer because it is the largest drainage catchment in Australia. It covers a vast area in the western part of the country and includes several major river systems such as the Fitzroy, Gascoyne, and Murchison. The Western Plateau receives rainfall from the monsoonal trough and experiences periodic flooding, which contributes to its role as a significant drainage catchment.
