-Sources of food supply; Fishing in Ocean, lakes and rivers are known to provide food for man in form of fish etc
- Agricultural purposes;water from rivers, lakes, wells, boreholes, etc are use for irrigation purposes
- Domestic uses; water from lakes, rain, rivers, boreholes are used for cooking, washing, bottling, and drinking

7a)The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas.
Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System.

ii)Dust
iii)Satellites
iv)Asteriods
v)Comets
7b)I) The earth is Spherical In Shape.
ii)Size: The diameter of the Earth at the equator is 12,756 km (7,926 miles), and its circumference or distance around the Earth at the equator is 40,075 km (24,901 miles).
iii)Composition: The composition of the Earth consists of the solid and liquid portion and the atmosphere or gaseous portion.

circumference or distance around the
Earth at the equator is 40,075 km (24,901

ii)Composition The composition of the Earth consists of the solid and liquid portion and the atmosphere or gaseous portion.
iii) Atmosphere The atmosphere of the Earth consists of 79% Nitrogen (N2), 20% Oxygen (O2) and
1% of other gases such as Carbon Dioxide
(CO2).
iv) Force fields The Earth has two major force fields: gravity and magnetism.
v) Gravity Gravity is the force at a distance that attracts objects of mass toward each
other. The force of gravity from the Earth
holds down our atmosphere, oceans and
everything else.
4a) i)Regions with a great deal of limestone often have karst topography.
ii)Suce Regions Possess rough surfaces above ground and cave systems below ground.
4b)The Process of Formation of limestone pillar otherwise known as limestone cave.
A limestone cave or cavern is a natural cavity that is formed underneath the Earth’s surface that can range from a few metres to many kilometres in length and depth.
Most of the world’s caves, including those at the Cradle of Humankind, are formed in porous limestone. Over millions of years, acidic groundwater or underground rivers dissolve away the limestone, leaving cavities which grow over time.
Early life forms appeared in the oceans about 3.8-billion years ago. These were single-celled, blue-green algae, called cyanobacteria, which made their own food through photosynthesis, releasing oxygen into the atmosphere in the process.
Dolomitic limestone, a sedimentary rock, was formed over millions of years through chemical reactions generated by these early organisms.
With movements within the Earth’s crust, the sedimentary dolomitic limestone eventually became exposed on dry land.
As time passed the limestone, which is permeable and soluble, was eroded by water. Weak carbonic acid in rainwater, reacting with the chemicals in the rock, dissolved and eroded away the limestone as the water filtered into the underlying depths of sediments. Large hollow solution cavities were formed in the limestone in this way.
Many cavities occur at various depths in a cave system due to the continual seepage and flow of the mildly acidic water through the deposits, while underground rivers may eventually carve their way through a mountainside, creating openings and entrances to the outside.
Other cave entrances include pit and depression areas that are located at the tops of caves..

4c)I) It is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar.
ii)As a reagent in flue-gas desulfurization, it reacts with sulfur dioxide for air pollution controllevels.
iii)It can be used for remineralizing and increasing the alkalinity of purified water to prevent pipe corrosion and to restore essential nutrient levels.
3a)i)Pllutonic rocks are rocks formed when magma cools and solidifies below the earth's surface, while volcanic rocks are rocks formed when lava cools and solidifies on the earth's surface.
ii)The mineral grains in volcanic rock in it are very small, while for plutonic rock The mineral grains in it are larger..
iii)plutonic rock are commonly used as building stone while volcanic rock is a hard and heavy rock.It is also used for building roads.
3b) Draw D diagram Your Fucking Self.
Crater Lake was formed when the magma chamber was vacated during the eruption of Mt. Mazama (the name of the actual mountain Crater Lake is in). The magma was ejected, leaving a big empty void under the mountain. Eventually, the mountain collapsed into itself, creating a deep crater, or caldera. This eventually filled with water, leaving the 2000ft deep lake we see today. Mt. Mazama did not blow its top off like Mt. Kilauea or Mt. St. Helens. Mazama's top was in tact until it collapsed into itself.
Kilauea blew its top, and due to continued eruptions, continues to reshape itself. Mt. Mazama is considered to be possibly active, and many think it will erupt again in the future, like many other volcanoes.
