A call to drift.identify with a new ID value not recognized by Drift will register this contact. Just be sure to use distinct ID values for distinct users. This ID might be numerical, or an email address, or a random string of characters. If your IDs are guessable (for instance, you use incremental IDs or email addresses), you will need to use our Signed Identities feature to ensure your identification process is secure. Just make sure that signed identities are not required in your widget security settings. If you use unguessable IDs, you can set this up with just a single line of JavaScript. You can do this with just a few lines of code.Īll you need is a unique user ID that your platform uses to identify whoever is on your website.

Plate tectonic explainEarthquakes Mountains volcanoes Įarthquakes and volcanoes occur mostly along or near trenches and mid-ocean ridges.
Sea flour spreadingAs the seafloor spreads apart at a mid-ocean ridge, new seafloor is created. Satellite measurements have confirmed that every year the Atlantic Ocean gets a few inches wider! The continents are still slowly moving, at about the speed your fingernails grow. Tsuchiya also recorded the video Pluspy in 1987, which, despite a decidedly odd name choice, became what many would consider to be the epicentre of drifting culture. India’s eventual collision with Eurasia would form the Himalayan Mountains Takahashi would eventually pass on his influence to a young Keiichi Tsuchiya, who is perhaps the most famous person in drifting and the first man to bear the title of Drift King. Notice that the breakup of Pangaea formed the Atlantic Ocean. The continents about 70 million years ago. The southern portion of Pangaea Gondwana, and the northern portion Laurasia. Pangaea about 200 million years ago, before it began breaking up. The magma which pushes up at the mid-ocean ridge provides the new land pushing the plates, and the subduction zones gobble up the land on the other side of the plates.The mechanism was convection currents!Ībout 225 million years ago, nearly all the land was united in one large land callledPangaea Mechanism for Plate TectonicsSeafloor Spreading provided insight to the mechanism for how the continents moved. According to the hypothesis of continental drift, continents have moved slowly to their current locations.Theory of continental was purposed by alferedwegner in (1912)
