The instrument is called a seismograph.
Salinity Is the measurement of minerals in the ocean waters.
Answer:
a. do not flow as far from the vent as basaltic lavas do
Explanation:
Rhyolites are known as volcanic rocks. Volcanic rocks are rocks formed when magma(semi liquid) from the aesthenosphere solidifies on the surface of the earth crust. Rhyolites is regarded as an extrusive igneous rock since magma creeps or erupt to the surface of the earth forming lava. This lava later solidifies due to cooling.
Eruption of magma can produce this kind of rock. As magma erupt from volcanoes it forms lava extending or spreading further not too far from the vent . The lava that solidifies to form rhyolites are usually felsic.
Rhyolites lava is very viscous and flows very slowly due to the high silica contents. so because of it very slow movement it does not flow as far from the vent as less viscous basaltic lavas do.
Answer:
