Final answer:
Mauna Loa on the island of Hawaii is an example of a shield volcano, much like Olympus Mons on Mars. Mauna Loa part of a chain of volcanic islands formed over a hot spot showcases the typical broad shape and vast size of shield volcanoes.
Step-by-step explanation:
An example of a shield volcano similar to Olympus Mons on Mars can be found on Earth in the form of the Mauna Loa, which is located on the island of Hawaii. Mauna Loa is one of the most massive volcanoes on our planet characterized by its broad, shield-like shape formed by the flow of low-viscosity lava that can travel great distances from the central vent. The Hawaiian shield volcanoes including Mauna Loa and Mauna Kea, have formed over a mantle hot spot that has been active for at least 100 million years.
The consistent activity from this hot spot, as Earth's plates move across it, has created a chain of volcanic islands. Compared to the stationary crust of Mars which allowed Olympus Mons to grow to immense heights, Earth's moving crust only permits somewhat smaller yet still impressive volcanic structures like Mauna Loa.
