Hegerberg had the chance to extend Norway’s lead but missed the penalty, sending it wide of the target.
Switzerland believed they were awarded a penalty when the referee ruled that Riesen was fouled in the box, but the decision was revoked after a VAR review.
Naalsund came on to replace former Red Vilde Boa Risa shortly after the hour mark, while Terland made her tournament debut by taking Hegerberg’s place.
In the other Group A match, Finland, who will face Norway next, secured a 1-0 victory against Iceland.
