A Scotsman providing free daily meals to 400,000 children, a former child soldier clearing land mines in Cambodia and a Texas builder giving injured vets mortgage-free homes are among the top 10 CNN Heroes of 2010.

This year marks CNN's fourth annual global search for everyday individuals changing the world. Since January, the network has aired weekly profiles of the Heroes, chosen from more than 10,000 nominations submitted by viewers in 100 countries. The top 10 — remarkable individuals chosen for their sacrifices and accomplishments — were revealed by CNN on Thursday.

A panel comprised of luminaries recognized for their own dedication to public service selected this year's top 10 CNN Heroes. The blue ribbon panel includes humanitarians, activists and philanthropists such as Muhammad Ali, Sir Richard Branson and Yo-Yo Ma.

In addition to the $25,000, each of this year's finalists will be honored at a televised gala, the CNN Heroes All-Star Tribute, airing on Thanksgiving night, November 25.

The global broadcast, with Anderson Cooper as the host, will culminate with the announcement of the CNN Hero of the Year, selected by the public in an online poll that began Thursday. The individual receiving the most votes will receive an additional $100,000.

Here are the top 10 Heroes of 2010:
