The Category 7 cable standard has been created to allow 10 Gigabit Ethernet over 100 m of copper cabling (also, 10 Gbit/s Ethernet now is typically run on Cat 6 A). The cable contains four twisted copper wire pairs, just like the earlier standards.he Category 7 cable standard has been created to allow 10 Gigabit Ethernet over 100 m of copper cabling (also, 10 Gbit/s Ethernet now is typically run on Cat 6 A).

Flooding occurs in a number of ways, and each may be affected by climate change. Surface water flooding occurs where heavy rainfall canât absorb into the ground or drain away. River flooding, closely linked to surface flooding, occurs when streams burst their banks.
Causes of flooding. A flood occurs when a river bursts its banks and the water spills onto the floodplain. Flooding tends to be caused by heavy rain: the faster the rainwater reaches the river channel [river channel: The part of the river that holds the water. ] , the more likely it is to flood.
