If you have to drive on a long trip, get plenty of rest before you leave and plan on stopping every hours.

You must stop every two hours.

Explanation:

Driving is a very responsible task that requires the driver's full attention. This attention will be impaired if the driver is tired, sleepy, or unwell. For this reason it is necessary that when making long trips the driver plans rest periods so that his attention is not harmed and endangers his life and the lives of others. Ideally, on long trips, the driver will plan the route and set stops so that he can rest every two hours.

the plates spread at mid-ocean ridges (they are divergent plate boundaries) which allows magma to rise through the weakness between the plates. the magma then emerges as lava from the boundary and cools, creating a new crust.
