I am known as the 'Empty Quarter,' holding the title of the largest continuous sand desert. My temperatures soar to extreme highs, yet I also experience some of the driest conditions on the planet. Historically, the frankincense trade routes traversed me. Which desert am I?

1. I am located primarily in the Arabian Peninsula.
2. I am larger than the country of France.
3. My dunes can reach heights of over 250 meters.
4. I am extremely sparsely populated.
