The landforms on the east and western part of the continent are very different, with the main reason being that the western part is geologically very active, while the eastern lacks geological activity.
Explanation:
The eastern part of the United States and Canada, or rather the eastern part of the North American continent, is a region that lacks geological activity for millions of years. This region can roughly be divided into two parts, one being dominated by the Appalachian Mountain Range, and the other being the plains. The Appalachians are medium high mountains, being heavily eroded, with smaller slopes, and covered with dense forests. The plains stretch along the coastline, but they are also very wide, and move several hundred of km into the mainland, making big portion of this region flat lowlands.
The western part, on the other hand, is geologically very active. There are several young mountain ranges which are still growing. There is volcanic activity, faults, and plateaus between the mountains. The coastal plains are very small and narrow. Because of the shadow effect, between the mountains there are arid zones where deserts and steppes dominate.

Answer:
c) No UV light until spring
Explanation:
According to research, chlorofluorocarbons also known as CFCs, are chemicals that are mainly responsible for the destruction of the ozone gas.
<em><u>This is all due to the interaction of different factors, and not only because of the presence of UV. </u></em>
In Antarctica, the ozone levels become significantly reduced during spring because of these chemicals that contain chlorine, producing a hole where cool air becomes trapped. This air produces clouds that are responsible of the release of chlorine from the CFCs, an extremely important process of the formation of an ozone hole. The more clouds there are, the more gases are released, and the worse the ozone hole will be in spring.
Because the sun rises and becomes more intense during spring, it degrades these gases and releases the free radicals of chlorine, which are highly detrimental for the ozone layer as they destroy numerous molecules of ozone. By the beginning of summer, there is a higher amount of ozone that comes from other areas which help fill the ozone hole.
Erosion. Sand is carried across the land through deposition where during the process many rocks along the way are reshaped.
Climate is the long-term pattern of weather in a particular area. Latitude is the greatest factor that determines climate in any given location. Correct answer: C Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Latitude determines climate, because different latitudes on Earth receive different amounts of sunlight. Higher latitudes receive less heat than lower latitude areas nearer the equator and average temperatures cool with increasing latitude, producing well-defined climatic zones on the planet.
