Answer:
it shows that a lot of our higher points like mountains used to be under water. it shows how the earth has change over billions of years
Explanation:
Answer:
Ferehnheit scale, the Celsius scale and Kelvin scale
Explanation:
There are three main scales commonly used in the world today to measure temperature: the Fahrenheit (°F) scale, the Celsius (°C) scale, and the Kelvin (K) scale. Each of these scales uses a different set of divisions based on different reference points.
Answer:
There is a gradual decline of volcanic age form the continental to the oceanic. As some of the volcanoes get eroded away.
Explanation:
- The hotspot volcanoes are transported by plate movements as they move away form the mantel plumes the hotspot volcanism decreases. Then eventually the hotspots become extinct.
- Thus on the basis of age the youngest are near the places active tectonism where the magma is directly ground underneath the ground surface.
Answer:
There is no drawing here to label but I will go on to explain the the various types of waves with a diagram
Explanation:
P wave or the primary waves are the fastest waves in seismic waves. It is usually the first to arrive at seismic station. P waves are called compressional waves because they have ability to pull and push rocks as they pass through them. It is the first waves you notice during an earthquake.
S waves or the secondary waves is slower than the primary waves and moves through solid rocks and can not pass through liquid. It travels outside the earth core, and that has made seismologist to believe that the outer crust is liquid. It moves rocks up and down, side by side.
Surface Waves only travel through the earth crust. It is slower than P and S waves. It is the surface waves that cause physical destruction we notice during earthquake. The strength and extent of damage of surface waves is determined by the depth of the earthquake.
