Answer:
Radiometric dating of basalt on the ocean floor provide us with an absolute age for the planet earth because the oceanic crust is recycled too frequently at subduction zones,
Explanation:
Radiometric dating of basalt on the ocean floor can not provide us the absolute age of the planet earth due to the subduction. In the process of subduction oceanic plate went below the continental plate as it is less denser. It then melts there and its recycling takes place frequently. So the radiometric dating of basalt on oceanic plate can not provide us the true information regarding the age of the earth.
Germany’s bank was stated in 1948 so in 1871 their competitors us started
Cliff collapse can cause land with houses, schools or places of work to be severely damaged or destroyed, this can result in people having to relocate which can cause express and sentimental distress (the impact of this is often greater on the elderly or families). Businesses that have been damaged / destroyed may have to close or make some people redundant if the economic impact on them was high; this has a large economic affect on the individual and any people dependent on them (e.g. Children / elderly parents) but this will also affect the entire community as there will be drops in the local economy which creates a multiplier affect.
Often coastal areas are tourism honeypot sites, if the cliff collapse causes lots of the sites tourists are interested in to be destroyed (e.g tourism shops, caravan sites) then lots of people employed in tourism may be may redundant, this has a wider affect than you may think (e.g. businesses that support this tourism such as companies that make scuba diving kit, dairies which provide milk for I've creams etc).
Answer:
The Primary sector of the economy includes any industry involved in the extraction and production of raw materials, such as farming, logging, hunting, fishing, and mining. The primary sector tends to make up a larger portion of the economy in developing countries than it does in developed countries.Explanation:
Answer:
with the help of ecolocation process like most using sound wave for example ultrasound is used to calculate ocean depth it has high frequency
Explanation:
a fathometer device is used .let the downward distance travelled use to bed of the ocean by the wave be d .when these waves reflect back from the bed of ocean and received by fathometer the upward distance travelled is also d hence total distance travelled is equal to 2d. if v be the velocity of waves in water and t be the the time taken for the waves to reach back to the fathometer the from the definition of speed
speed =distance travelled÷ time taken=2d÷t
d=v×t÷2
