the netherlands protects its lowland areas:
A)with dikes to hold back the sea
B)with dikes to hold in rivers
my choose b
hi ms.sue!
Hi Henry.
Nope. The Netherlands doesn't have major rivers. This is a country that is mostly below sea level and needs dikes to protect it from flooding from the sea.
oh o.k its a then sorry.ill try harder next time :)
Correction: The Netherlands has one major river -- the Rhine which empties into the sea here. However, the dikes are used to hold back the sea -- not the river.
its a right
Hi there! It seems like you've chosen option B - that the Netherlands protects its lowland areas with dikes to hold in rivers.
Actually, both options A and B are correct. The Netherlands protects its lowland areas using a combination of dikes, or levees, to hold back the sea as well as to hold in rivers. These dikes, or embankments, act as barriers to prevent flooding from both the ocean and rivers.
To understand why both options are correct, let me explain a bit more about the geographical situation of the Netherlands. The country is located largely below sea level, with a significant portion of its land situated in low-lying areas vulnerable to flooding. The presence of rivers and coastal areas make it necessary for the Netherlands to have a robust system for flood protection.
To hold back the sea, the Netherlands has built an extensive network of dikes, also known as sea dikes or coastal dikes. These dikes line the coastline and prevent the sea from encroaching onto the land. They are designed to absorb the force of waves and tides, providing a barrier against storm surges and high water levels.
Furthermore, the Netherlands has an intricate system of dikes along rivers, known as river dikes or river levees. These dikes are specifically designed to contain the flow of rivers within their channels, preventing them from flooding surrounding areas. They help regulate the water levels during periods of heavy rainfall or snowmelt.
By having both kinds of dikes - sea dikes to hold back the sea and river dikes to hold in rivers - the Netherlands is able to protect its lowland areas from the threat of flooding, which is essential for a country that experiences high levels of water in its surroundings.
I hope this explanation helps! Let me know if you have any further questions.
