Scott's goal came in the third minute to open the scoring.
Jill Scott got the rout started by smartly sweeping home an inviting cross after striker Ellen White fortuitously mistimed her effort. Bronze attempted to pass the soccer ball to White, however White fanned on the shot. After a great play down at the right flank with Lucy Bronze who played the ball inside to Parris, who plays it into the path of White. Just because she plays at right-back... she is the best.
The Lionesses started on the front foot, recording their fastest ever goal in the World Cup timed at 2 minutes and 6 seconds. England manager Hope Powell accused some of her senior players of "cowardice" for not volunteering to take a penalty.
Nodding in approval from the stands was David Beckham, who high-fived Sue Campbell, the head of women's soccer in England.
The Lionesses have never won a major trophy, but this is their third consecutive semi-final - reaching the last four in 2015 and Euro 2017 under former boss Mark Sampson.
Phil Neville's squad will no doubt take confidence from the 30-year-old's inspired form, which, if maintained, will give England a real chance of reaching the final.

Neville's side suggested against Norway that they are good enough to go all the way this time, not least thanks to the performance of right-back Bronze, who drew praise from all quarters afterwards.
A video message from retired rowing champion Katherine Grainger, Britain's most decorated female Olympian, was played in the team meeting.
"People can say sometimes "that's a bit risky, you're taking your eyes off the game". We've put in so many hours and suffered at times throughout this journey over the last two years. "We want to play both of them (USA or France)", said Neville, who took in charge of England as his first coaching job in women's soccer early past year.
Despite a concerning medical update from Neville on the eve of the game about Millie Bright's sickness, she made the starting lineup.
Norway continued to ask questions of an England defence that has conceded just once at this tournament, but couldn't find a way past as Steph Houghton put in a solid display that included a crucial goal-line clearance after Millie Bright had put her team in trouble with a short backpass.
Parris should have done better as she shanked wide after working space on her left foot in the area, before White crashed a powerful strike against the post from a similarly promising position. After netting from the spot in the opening game against Scotland, she was also denied against Argentina in the group stage. She is our best penalty taker.
