- The North American and European continents are moving apart at a rate of about 3 cm/y. At this rate how long will it take them to drift 500 km farther apart than they are at present?Given that Earth is about 4.6 billion (4.6 x 10%) years old, how many precessional cycles have occurred?Which has the higher tides: spring tides or neap tides?
- The figure shows, not to scale, a cross section through the interior of Earth. Rather than being uniform throughout, Earth is divided into three zones: an outer crust, a mantle, and an inner core. The dimensions of these zones and the masses contained within them are shown on the figure. Earth has a total mass of 5.98 x 1024 kg and a radius of 6370 km. Ignore rotation and assume that Earth is spherical. (a) Calculate ag at the surface. (b) Suppose that a bore hole (the Mohole) is driven to the crust-mantle interface at a depth of 25.0 km; what would be the value of ag at the bottom of the hole? (c) Suppose that Earth were a uniform sphere with the same total mass and size. What would be the value of ag at a depth of 25.0 km? (Precise measurements of ag are sensitive probes of the interior structure of Earth, although results can be clouded by local variations in mass distribution.) 6345 km (a) Number (b) Number 25 km Number i 3490 km -Core, 1.93 x 1024 kg Mantle, 4.01 × 1024 kg Crust,…When do the greatest tidal ranges occur?The London Eye has a diameter of 135 meters. A rider boards the London Eye at ground level. Through what angle ? has the wheel rotated when the rider is 32.5 meters above ground for the first time? (Round your answer to one decimal place.)
