(i) It is cost effective and requires less manpower as it is tool-based.
(ii) It requires field study to interpret data into useful information
=REMOTE SENSING=
(i) It is a costly affair as the data is incurred from space and through sensors and satellites.
(ii) It reduces manual work and ground field study.
(8b)
(i) In Telecommunication: Satellite remote sensing have been found to be more useful and relevant in telecommunication. The satellite remote sensing has made it possible for regional, national and international communication without being in direct contact with human beings.
(ii) In Transportation: The availability of high resolution commercial remote sensing has contributed to a revolution to the transport network. The satellite remote sensing is useful to transportation, it helps to improve the trafficability of the roads and also contributed greatly in the movement of aero planes, jets and even seen beyond the bonds of human eye sight.

(i)
The texture of a rock is the size, shape, and arrangement of the grains (for sedimentary rocks) or crystals (for igneous and metamorphic rocks. Example includes: basalt, andesite and rhyolite.
(ii)
The structure of an igneous rock is normally taken to comprise the mutual relationships of mineral or mineral-glass aggregates that have contrasting textures, along with layering, fractures, and other larger-scale features that transect or bound such aggregates.
(iii) Colour: Color index is an indicator of the types of minerals present, and the specific type of rock. The color index of an igneous rock is a measure of the ratio of dark colored, or mafic, minerals to light colored, or felsic, minerals.
(3b)
PLUTONIC ROCKS
- Plutonic rocks are formed when magma cools and solidifies underground.
- It cools at a very slow rate and may take thousands or millions of years to solidify.
VOLCANIC ROCKS
- Volcanic rocks are formed from lava that flows on the surface of the Earth and other planets and then cools and solidifies.
- It doesn't cool at a very slow rate and it doesn't take thousands or millions of years to solidify.

(i) Weather is the atmospheric over a condition of a place short period (days, weeks, hours, months).
(ii) Weather changes very often.
(iii) Weather cannot be generalized.
(UNDER CLIMATE)
(i) Climate is the average condition of a place over a long period of time (35 years).
(ii) Climate does not change very often.
(iii) Climate can be generalized.

(7a)
Environmental resources refer to any useful item in the environment, or materials and substances that are useful to man. In other words, environmental resources are useful things (both living and non-living) occurring naturally within a particular geographical location which are of benefit to man, animals and plants.

(Pick Any Four)
(i) Atmospheric resources
(ii)Water Resources
(iii) Vegetation Resources
(iv)Human Resources
(v)Mineral Resources
(vi)Land Resources
(7c)
(Pick Any Two)
(i) Industrial development and source of ornaments:Diamond,iron ,copper,silver and graphite are useful for industrial development e.g diamond, the hardest know metal is used in cutting other metals and graphite is used in making pencil. Some mineral like gold, silver,bronze are used as ornamental ware or jewellery. Gold is the most valuable metal used in making wrist watches,chains etc
(ii)Source of foreign exchange and provision of employment: Most mineral sold to other countries provide foreign exchange for development eg petroleum in Nigeria. People engaged in the morning of these minerals get jobs as miners, drillers , engineering.. It contribute to economic development of a nation
(iii)source of timber and firewood: Timber like Iroko ,obeche ,Mahogany etc are sources of planks and plywood used for building and furniture. Timber also provides foreign exchange for nation. Firewood is used to provide fuel for cooking food, warning the body during cold weather ,for drying fish etc. They are contribute in economic development of a nation
(iv) Development of game resource and Tourism: Forest and savanna are the home of wildlife which can serve as game reserve eg Yankari Games Reserve. Forest and Savanna are also centres of tourism which can also generate foreign exchange to nations.An increase in tourism flow can bring positive economic outcomes to the nations

- Habitat loss: Rising temperatures affect vegetation, food sources, access to water and much more. Ecosystems may become uninhabitable for certain animals, forcing wildlife to migrate outside of their usual patterns in search of food and livable conditions, while causing other animals to die off.
- Natural disasters: Already today we face a five-fold increase, compared to 50 years ago, in climate and weather-related natural disasters such as droughts, wildfires and hurricanes. These disasters cause catastrophic loss of life and habitat for people, pets and wildlife.
- Extinction: The combination of challenges could cause many animals to go extinct. The world’s most vulnerable animals, including those already near extinction, will likely face the biggest threats.
