Why are hot springs hot?
A
The ground water gets heated by nearby magma.
B
They just are
C
The water is warmed by solar energy
D
The ground water comes to the surface and warms up the closer it gets.
Explanation: 

Detailed explanation-1: -Hot springs are heated by geothermal heat-heat from the Earth’s interior. In volcanic areas, water may come into contact with very hot rock heated by magma. Hot springs in active volcanic zones may produce superheated water, so hot that immersion can result in injury or death.

Detailed explanation-2: -Hot springs and geysers also are manifestations of volcanic activity. They result from the interaction of groundwater with magma or with solidified but still-hot igneous rocks at shallow depths.

Detailed explanation-3: -A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through faults to hot rock deep in the Earth’s crust.

Detailed explanation-4: -A hot spring is a discharge of hot (>35–40°C) water from a vent at the Earth’s surface. A geyser is a hot spring characterized by intermittent, turbulent discharges of boiling water and steam. A sublacustrine hot spring is a hot spring that discharges from the floor of a lake.

Detailed explanation-5: -If underground rock formations are heated to about 700-1, 300° C (1, 300-2, 400° F), they can become magma. Magma is molten (partly melted) rock permeated by gas and gas bubbles. Magma exists in the mantle and lower crust, and sometimes bubbles to the surface as lava. Magma heats nearby rocks and underground aquifers.
