Free Weather, Climate and Adaptations of Animals to Climate 01 Practice Test - 7th grade
Question 1
The lion-tailed macaque (also called beard ape) is found in which of the following regions?
Eastern Ghats
Western Ghats
Vindhyas
Thar Desert
SOLUTION
Solution : B
The lion-tailed macaque (also called beard ape) lives in the rainforests of Western Ghats, a mountain range that runs almost parallel to the western coast of the Indian peninsula. This region is well known for its rich and unique flora and fauna.
Question 2
What causes the changes in weather conditions?
SOLUTION
Solution : A
Sun is the central ball of fire around which all planets move. The weather conditions on earth change depending on the amount of sunlight reaching the earth. The tilt of Earth’s axis relative to its orbit around the Sun results in changes in the duration of daylight and the amount of sunlight received at any place throughout the year. These changes cause the annual cycle of seasons. Therefore, we experience different weather conditions.
Question 3
The average atmospheric conditions of a place taken over a short interval of time is called _____________.
temperature
climate
weather
pressure
SOLUTION
Solution : C
Weather is defined as the atmospheric conditions of a specific place over a short interval of time. Whereas, climate is a long term pattern of weather changes in an area.
Question 4
The maximum temperature of the day is usually recorded in the ______________.
SOLUTION
Solution : C
In the afternoon, the Sun is overhead and the rays reach us directly. Hence, for most days, the temperature is maximum around this time. However, it may be noted that this is not a compulsory rule. There may be days when the afternoon is colder due to events like rainfall, snowfall, etc.
Question 5
Which of these animals live in the polar regions?
tigers
dogs
penguins
peacocks
SOLUTION
Solution : C
Penguins live in the polar regions. These regions are covered with snow throughout the year so the organisms living in these areas have features that support their survival.
Question 6
The climate in tropical region is generally:
hot
cold
moderate
dry
SOLUTION
Solution : A
The climate in tropical region is generally hot. The tropics are regions of the Earth which are near the equator and between the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere. These regions receive direct sunlight throughout the year and hence the temperature in these regions is high.
Question 7
Select the instrument that is used to measure rainfall.
SOLUTION
Solution : D
∙ Rain gauge is an instrument that is used for collecting and measuring rainfall.∙ Thermometre is an instrument that is used to measure temperature.
∙ Barometre is an instrument which is used to measure the air pressure.
∙ Anemometre is an instrument that is used for measuring wind speed.
Question 8
The phenomenon by which birds escape from harsh and cold weather conditions is termed __.
SOLUTION
Solution : C
Birds need warm weather for survival. When the climate turns cold, birds fly away in groups to places with warmer climates which is suitable for their survival. This phenomenon is called migration. The birds return to their homes when the climate becomes favourable for them.
Question 9
The region which receives very little rainfall or precipitation is called a __.
SOLUTION
Solution : A
The region which receives very little rainfall is called a desert. The lack of precipitation makes the region quite hostile for normal plant and animal life. Tropical rain forests get the maximum rainfall.
Question 10
__ is defined as the amount of moisture in the air.
SOLUTION
Solution : B
The amount of moisture present in the air is termed humidity. Humidity indicates the likelihood of precipitation, dew or fog. Drought is the long term shortage of water which makes life difficult.
