How is cancer treated in a technique called teletherapy?

Teletherapy is the external radiotherapy that uses an external source of radiation to kill the tumor cells.

Explanation:

Teletherapy is the external radiotherapy that uses an external source of radiation to deliver the radiations such as gamma rays or high energy x rays to kill the tumor cells. Teletherapy is a noninvasive treatment method of cancer and uses the ionizing radiations to target the cancer cells. To minimize the harmful effects on healthy tissues, radiations are given at different angles.

i think the miocene epoch spans the time from 23 million to 12 million years ago.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
