How does GPS help predict volcanic eruptions? The ground swells slightly before an eruption. GPS devices can detect the swelling.
GPS satellites can see into the cone of the volcano.

The magma carries a GPS device as it travels. Scientists can track the flow of magma by adding more GPS devices to magma.

GPS devices can detect when gases leave a volcano before an eruption.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

the answer is c i took the test
