Q

Soil erosion and degradation : Topsoil is washed or blown away

A

reducing fertility and making it harder for crops and plants to grow. It also leads to desertification in severe cases.

Q

Latitude: Areas closer to the equator receive more direct sunlight

A

making them warmer. Areas near the poles get slanted rays

25
Altitude:
Higher altitudes are colder because the air becomes thinner and less able to hold heat. Refers to the height of a place above sea level
26
Proximity to Water: Water heats and cools more slowly than land. Places near oceans or large lakes have milder climates
with cooler summers and warmer winters. Coastal regions tend to have milder climates than inland areas.
27
Prevailing winds: Refers to the dominant wind direction in a particular area. They can bring moisture from oceans
creating wet climates or dry air from desserts. The direction and strength of prevailing winds can significantly impact rainfall patterns and temperature distribution.
28
Topography : Refers to the physical features of the earth’s surface
such as mountains and valleys. The shape and orientation of landforms can also affect wind patterns and temperatures.
29
Ocean currents : large scale movements of water in the oceans. Warm oceans currents can carry heat temperature towards higher latitudes
moderating the climate of coastal areas. Cold ocean currents can bring cool air and affect rainfall patterns
30
Vegetation : can influence local weather patterns by affecting albedo [reflectivity of a surface : affecting solar radiation]
water cycles [ contributing to humidity and rainfall ] and soil moisture.
31
Greenhouse gases
also affect the earth's climate as they trap the heat in the atmosphere leading to global warming.
32
How location impacts temperature and how air pressure affects the weather
new topic
33
Location does impact ...
temperature due to factors like latitude altitude and proximity to the water.
34
Air pressure influences weather conditions by
drawing wind patterns cloud formation and precipitation.
35
Is related to temperature
warmer air is less dense and rises
36
Difference in air pressure drives winds
air moves from areas of high pressure to areas of low pressure attempting to balance the pressure gradient (atmosphere). This movement can carry heat
37
Clouds and precipitation
38
Rising air in low pressure areas can cool and condense forming clouds and potentially precipitate.
39
High and low pressure systems :
high pressure systems are associated with clean skies and stable weather. Low pressure systems are linked to cloudy skies wind and precipitation.
40
Value of landforms
41
Landforms are valuable because they influence various aspects of life
(earth) including biodiversity human activities and resource management (agriculture & industry). They provide resources like minerals
42
Mountains : They can influence the climate around them
rainfall patterns and temperatures in surrounding areas. Blocking winds cause rain to fall on one side
43
Lakes and Rivers : they provide drinking water
irrigation for agriculture and hydroelectric power making them important water resources. They are valuable transportation routes as well
44
Plateaus : Large
flat area that is slightly raised or gently sloping landform. Can support agriculture (livestock grazing)
45
Plains :. Is most suitable for agriculture
providing fertile soil. Also suitable for infrastructure growth
46
Cultural
47
They are integral parts of human culture
shaping personal understanding
48
Spiritual
49
Natural features linked to creation of myths and ancestral stories. Serving as social sites and mountains for example are often seen as gateways to the heavens or as the home of certain deities where one can feel connected to the divine. This enhances spiritual value. An example can be rivers and lakes
they are vital sources of life and purification. Water is commonly used in rituals and ceremonies for spiritual cleansing. Coves and grottoes in some cultures caves are used as burial sites and places of ancestor worship. They can be used for meditation and prayer. Desserts can be a place of contemplation and spiritual growth due to its vastres.
50
Economic
51
Provide valuable resources like minerals
timber and water. Plains are ideal for agriculture
52
Aesthetic
Refers to the value of a landscape for its beauty or majesty. Its overall visual appeal enhances our appreciation of nature and can deepen our connection to the environment. Beautiful landscapes full of life (plants & animals different landforms etc
53
Intrinsic
54
Intrinsic landforms and landscapes influence climate
soil fertility
55
Competing values
56
Arise when different stakeholders have conflicting interests about how landforms should be used or protected oftentimes due to economic
social and environmental considerations. An example of this can be a mountain
57
Cultural value (poetry
literature
58
It is expressed by pepe through creative means such as art
poetry
59
Spiritual value
60
Spiritual value refers to the deep connection people feel toward certain natural places due to cultural beliefs
religious practices
61
Economic value (mining
resources
62
A coastal area can be valuable for tourism and recreation
however it can also be very useful for mining and infrastructure and developing fisheries. development of fisheries and other industrial systems can also harm the surrounding environment and its resources. The desire to maximize economic gains from development might conflict with the need to protect the environment and its resources. This creates competing values particularly between development and conservation.
