How many tectonic plates are there on Earth?

Are there tectonic plates on Mars?

Mars, however, doesn’t have plate tectonics. After its formation, the planet was a searing mass of molten rock that eventually cooled to form a static crust around a rocky mantle, yet it’s unclear how hot the planet’s insides are today.
