Final answer:
All mentioned parks, including Joshua Tree National Park, Sequoia National Park, and Yosemite National Park, are in the state of California. They are part of the national parks system originally established with the Yosemite Grant Act of 1864.
Step-by-step explanation:
Joshua Tree National Park, Sequoia National Park, Kings Canyon National Park, Death Valley National Park, Yosemite National Park, Lassen National Park, and Redwood National Park are all located in the state of California.
These parks are renowned for their unique natural features, such as the giant sequoias in Sequoia National Park, the rugged desert landscapes in Joshua Tree National Park, and the iconic, misty waterfalls in Yosemite National Park.
The establishment of these parks can be traced back to legislation like the Yosemite Grant Act of 1864, signed by President Lincoln, which laid the groundwork for the national park system that preserves these magnificent landscapes for the benefit of the public and ecological preservation.
