________  are made of soil.

Soil is made up of mineral particles, organic materials, air, and water.

Soil is characterized by color , texture , structure , and acidity or alkalinity (affects the presence of nutrients in the soil).

that forms humus, which come from the remains of plants and animals that have been broken down by decomposers such as bacteria, fungi, and some insects.

Darker soil indicates greater amount of humus which affects the ability to retain moisture.

What are the types of soil?

Characteristics of clay

Sand has grainy texture and can be easily scattered. It is loose, coarse, and dry. It does not retain much moisture and nutrients.

It contains different organic materials such as dried leaves and branches.

It is ideal for gardening and commonly used to grow flowers, small garden, fruits, and vegetables.

It can be used for agriculture and home gardens by adding organic matter (compost) that gives structure, texture, and nutrients.

Dark yellow to brown in color.

Major Sources

It is the water coming from different bodies of water such as lakes, seas, oceans, streams, and rivers.

It is the water that comes from rainwater that gets deposited in the ground. Springs and wells are groundwater sources.

It is the journey that water takes as it travels from bodies of water to the sky and back.

Because of the Sun's heat, surface water in the different bodies of water evaporates.

Plants do not give off water through transpiration.

The water that has evaporated or transpired is now present in the air as water vapor.

Water vapor in the air eventually condenses, forming tiny droplets of water in the clouds.

When the clouds become lighter , water droplets fall in the process called precipitation.

Precipitation can be in the form of rain, snow, or hail.

Some of the water that seeps into the ground gets trapped in rock layers, forming surface water

Most of the water will flow downhill as runoff, eventually returning to the different bodies of water.

Uses of water

Water produced commercially includes distilled, mineral, purified, and alkaline water.

 There are no companies that produce clean water for drinking.

Water is also used as a coolant to ensure that machines do not overheat.

Water can't be used to clean machineries in industries and factories.

Water is used as a source of Energy.

Hydrothermal energy can be derived from hot springs and water sources near volcanoes. The heat from these water resources is transformed into electrical energy.

A dam is not a source of hydroelectric energy.

Moving water causes turbines to turn, and thus produce electricity.

Hydroelectric energy can be derived from moving water.

Water can't be used as an alternative energy source. The energy derived from water can either be hydrothermal or hydroelectric.

Water is used to clean the body, clothes, dishes, cars, and other things at home.

Drinking water after strenuous activities help replace the water that is lost through sweating.

Drink at least 6 glasses of water to make sure that the body is properly hydrated.

Water is needed by the body to function properly.
