Answer 1

Explanation:

5. How are earthquakes distributed on the earth?

Earthquakes are not randomly distributed around the earth, rather they are located in distinct zones which can be related to the margins of tectonic plates on the Earth's surface.

3. Explain the distribution of volcanoes

Volcanoes are distributed all around the world, mostly along the edges of tectonic Plates , although there are intra-plate volcanoes that form from mantle Hotspots (eg, Hawaii). Some volcanic regions, such as Iceland, happen to occur where there is both a hotspot and a plate boundary.

2. Explain with examples three different types of volcanoes.

There are three main types of volcano -

composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. ... This viscous lava has a lot to do with why they are shaped the way they are

4. What are earthquake waves? How do we measure earthquakes?

Earthquakes are measured using seismographs, which monitor the seismic waves that travel through the Earth after an earthquake strikes. Scientists used the Richter Scale for many years but now largely follow the "moment magnitude scale," which the U.S. Geological Survey says is a more accurate measure of size.

Earthquakes release waves of energy called seismic waves. They travel through the interior and near the surface of the Earth. P-waves, or primary waves, are the fastest moving type of wave and the first detected by seismographs.

1. Explain the two theories given to explain the earth's movements.

There are 2 theories which explain the earth's movements namely the Continental Drift Theory and the Plate tectonics theory. ...  The earth was a single sialic land mass called Pangaea surrounded by a huge ocean called Panthalasa whose floor was a mass of sima.  Pangaea broke into two parts called Laurasia

Answer 2

Answer:

1. There are 2 theories which explain the earth's movements namely the Continental Drift Theory and the Plate tectonics theory. Its proponent was A. Wegener. It explains the origin of 6 continents.

2.There are three main types of volcano - composite or strato, shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. ... This viscous lava has a lot to do with why they are shaped the way they are.

3.Distribution of volcanic activity

Volcanoes are most likely to occur along the margins of tectonic plates, especially in subduction zones where oceanic plates dive under continental plates. As the oceanic plate subducts beneath the surface, intense heat and pressure melts the rock.
