Answer from: morkitus13

Human activities can have an impact on natural disasters:

Burning activities cause global warmingirresponsible miningBuilding damsFracking for oil and natural gasDeforestation Urban development Natural wetland destruction Agricultural activities Hydroelectric power

These activities lead to earthquakes, floods, Avalanches, landslides

Explanation:

Irresponsible mining led to the permanent landscape modifications. because of the drilling of the salt mine beneath the lake. More than that, mining increases the occurrence of earthquakes

Building dams can cause earthquakes because of the huge water mass that applies pressure on the surface beneath.

Fracking for oil and natural gas Wastewater used in the process causes earthquakes as it cracks rocks and lubricates faults.

Deforestation People destroy vegetation that protects the topsoil and absorbs excess rainwater with its roots. As a result, high water freely spreads in the region causes floods .

Agriculture similar to deforestation, destroys the topsoil so it has to possibility to absorb rainwater, causes floods.

Urban development: all the surfaces in the town or city are covered with cement or asphalt. Naturally, these materials do not absorb rainwater so it may cause floods.

Destruction of the natural wetlands. destroy natural obstacles for water collection areas. As a result, excess water finds new ways and they all trend near or through human settlements causes floods.

Hydroelectric power is impossible without dam building. Apart from the dangers of earthquakes, dams can cause floods. The whole process of obtaining electric power through the water power plant requires a huge reservoir of water which flow is accurately regulated. Any miscalculate may lead to the catastrophe.

And many activities that increases carbon dioxide and other warm gases lead to global warming which causes many disaster.

Answer from: Quest

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student, including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as edutech.
