i think its b ? am aint sure
Answer: The model is depicting the glacier erosion.
Explanation:
The glaciers are responsible for causing erosion of the earth. They transport the materials away from the locations were they are earlier situated. They carve the materials present beneath the land. They erode the materials like soil, pebbles, boulders, against the pressure of the unstable mass of the ice moving down the slope. The broken ice mass carriers away the broken rocks, materials and soil debris far away from the places where they have been originally situated. This causes the glacial erosion. Also the broken and displaced rocks displace the soil and other materials come in contact with during erosion.
According to the given situation, the ice formed with water only had no impact on the tinfoil on the other hand the ice containing the sand and rocks removed the tinfoil from places. This is because of the friction created by the sand and rocks on the tinfoil. The glacier material like ice, soil, rocks due to friction erode the material come in contact with it with an appreciable pressure underneath.

The polar jet stream expresses seasonal change. <em>The change in the </em><em>polar jet stream</em><em> from summer to winter position causes </em><em>cooler temperatures</em><em> farther south and causes </em><em> storms</em><em> to move more rapidly. Option 4.</em>
<h3 /><h3>Jet Streams</h3>
- A jet stream is a strong and narrow air stream concentrated along the horizontal axis in the troposphere.
- The stream wide is about 200 km, and its thickness ranges between 5,000 and 7,000 m.
- The strongest winds are in the central region of the stream, known as the jet core, with a speed of about 120 km/hour.
<h3>Types</h3><h3 />
- There are five jet stream types.
- Two polar streams ⇒ one of them in the northern hemisphere and the other one in the southern hemisphere.
- Two subtropical streams ⇒ one of them in the northern hemisphere and the other one in the southern hemisphere.
Both of them are west streams. And the polar ones are stronger than the subtropical ones.
- The tropical stream that comes from the east.
<h3 /><h3>Polar Jet Stream</h3><h3 />
- In the northern hemisphere, the polar jet stream affects mainly the Iberian peninsula.
- It gets formed in the convergence region, where the cooler winds from the Pole and the warmer winds from the Equator meet.
- This stream surrounds the Earth making several waves on its course.
- It occurs a seasonal balance between the winter and summer
→ Winter ⇒ The polar jet stream places between 35 and 40º latitude.
→ Summer ⇒ The polar jet stream is placed at about 50º latitude.
Following this seasonal change, from summer to winter cooler air masses reach lower latitudes and might be the cause of severe winter storms.
According to this framework, we can assume that <em>the </em><em>change</em><em> in the </em><em>polar front jet stream</em><em> from summer position to winter position causes </em><em>cooler temperatures</em><em> farther </em><em>south </em><em>and causes </em><em>storms</em><em> to move more rapidly. </em>
The correct option is (4).
