Which one of the following statements with regard to volcanoes is not correct?

Hawaiian shield volcanoes are eroded by steams that form deeply carved valleys with steeply sloping heads.

The surrounding areas can remain highlands, lava ridges or mesas.

Stratovolcanoes produce lava flows that initially follow valleys but are highly resistant to erosion.

The system of streams on a dissected volcano cone is not a radial drainage pattern.

Correct Answer : The system of streams on a dissected volcano cone is not a radial drainage pattern.

Stratovolcano, also known as acomposite volcano, is aconical volcanobuilt up by many layers (strata) of hardened lava, tephra, pumice and ash. Because it is stratified, therefore it will definitely form a volcano cone.

How much time does a Geostationary satellite take to complete one orbit, at the height of 35790 km?

12 hours

24 hours

45 days

365 days

Correct Answer : 24 hours

As the height of a satellite increases, so the time for the satellite to orbit increases. At a height of 35790 km, it takes 24 hours for the satellite to orbit. This type of orbit is known as a geosynchronous orbit, i.e. it is synchronized with the Earth.

One particular form of geosynchronous orbit is known as a geostationary orbit. In this type of orbit the satellite rotates in the same direction as the rotation of the Earth and has an approximate 24 hour period. This means that it revolves at the same angular velocity as the Earth and in the same direction and therefore remains in the same position relative to the Earth.
