Which of the following describes an impact of floods on ecosystems? Strong winds uproot small plants and trees. Soil erosion along rivers prevent plants from getting sunlight. Homes will be destroyed and people will be injured.
Which of the following describes an impact of floods on an ecosystem?
If a flood is large enough, it can result in a loss of wildlife and biodiversity in the flooded region. This may reduce the level of biodiversity, habitat potential and food present in the ecosystem, creating long-term impacts for surviving wildlife.
Which event in the formation of stalactites is an example of weathering?
Stalactites and stalagmites are formed by chemical weathering. Water dissolves the calcites in the rock of a cave roof and the calcite is deposited as strange and wonderful structures below.
Why would life on Earth be unlikely to survive if the liquid iron core did not produce a magnetic field Quizizz?
Why would life on Earth be unlikely to survive if the liquid iron core did not produce a magnetic field? Oxygen would not be attracted to the lower atmosphere which would not allow for respiration. … The Moon is the most likely celestial body to have life.
What are the impact of floods?
Loss of lives and property: Immediate impacts of flooding include loss of human life, damage to property, destruction of crops, loss of livestock, non-functioning of infrastructure facilities and deterioration of health condition owing to waterborne diseases.
What are the effects of floods on the environment?
The environment also suffers when floods occur. Moreover, chemicals and other hazardous substances end up in water and eventually contaminate the water bodies that floods end up in. In addition, flooding can destroy the natural balance of the ecosystem.
What type of weathering affects stalactites?
Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. … Water also interacts with calcites in caves, causing them to dissolve. Calcite in dripping water builds up over many years to create stalagmites and stalactites.
How does weathering affect caves?
Explanation: Dissolution. Water picks up carbon dioxide from the air and as it filters into the soil, it turns into a weak acid that can dissolve limestone and if it goes on long enough and creates a big enough “underground hole” it can form a cave. Hope I helped, Good day!
How stalactites and stalagmites are formed in limestone caves?
Stalactites grow down from the cave ceiling, while stalagmites grow up from the cave floor. … As the carbon dioxide is released, calcite is precipitated (redeposited) on cave walls, ceilings and floors. As the redeposited minerals build up after countless water drops, a stalactite is formed.
What best describes what has happened to the iron in the nail that causes it to become magnetic?
What best describes what has happened to the iron in the nail that causes it to become magnetic? A physical change has occurred, because the chemical properties of iron remain the same. A physical change has occurred, because the chemical attraction between the iron and paper clips.
Which of the following characteristics of the sun helps life to exist on Earth?
The sun is the closest star to Earth. Even at a distance of 150 million kilometers (93 million miles), its gravitational pull holds the planet in orbit. It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth.
Which of the following characteristics of earth are essential to the existence of life?
What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
What are economic impacts of flooding?
In addition to causing damage to homes, businesses, agriculture and transport networks, flooding can significantly decrease a country’s gross domestic product (GDP) in direct proportion to the area of land flooded.
What are the effects of flood on agriculture?
Huge amount of agricultural land is being brushed away and crops go under water through river erosion, sedimentation and inundation caused by the floods. Agriculture sector is mostly affected during flood. The foremost adverse effect of flood on agriculture is water logging in the cropping area.
What are the effects of flood and drought?
Examples of drought impacts on society include anxiety or depression over economic losses, conflicts when there is insufficient water, lower incomes, fewer recreational activities, higher heat stroke incidents and even loss of human life.
