- Atiny particles that make up all matter.
- Btiny particles that can only be seen with a microscope.
- Ctiny particles that look like gnats.
2The components of a mixture can be easily separated and each keep their original properties. The proportion of the components is variable
- ATrue
- BFalse

What types of mixtures do you know?
- AThere are three main categories of mixtures: homogeneous mixtures, heterogeneous mixtures and salty mixtures.
- BThere are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures.
- CThere are two main categories of mixtures: pure substances and compounds.
4Renewable energy sources are all around us. Ex: Solar (from the sun), wind, water, geothermal (from the earth) and [blank_start]biomass[blank_end] (from organic materials).
- Abiomass
- Borganic
- Cwater
5The type of energy that is found under the earth is called Geothermal energy.
- ATrue
- BFalse
6What is the difference between a solution and a mixture?
In chemistry a [blank_start]solution[blank_end] is actually a type of [blank_start]mixture[blank_end]. A solution is a mixture that is the same or uniform throughout. Think of the example of salt water. This is also called a "homogenous mixture." A mixture that is not a solution is not uniform throughout. Think of the example of sand in water. This is also called a "[blank_start]heterogeneous[blank_end] mixture- Amixture
- Bsolution
- Cheterogeneous
7How does COVID-19 spread?
People can catch COVID-19 from others who have the [blank_start]virus[blank_end]. The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with COVID-19 coughs or exhales. These droplets land on objects and surfaces around the person. Other people then catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth. People can also catch COVID-19 if they breathe in droplets from a person with COVID-19 who coughs out or exhales droplets. This is why it is important to stay more than 1 meter (3 feet) away from a person who is sick.- Avirus
- Bpeople
- Csick
82. What are the symptoms of COVID-19?
The most common symptoms of COVID-19 are [blank_start]fever[blank_end], tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea.
- Afever
- Bhappiness
- Ccough
9I am well and asymptomatic. Should I use a mask?
- ATrue
- BFalse
10A [blank_start]volcanologist[blank_end] or vulcanologist is a geologist who studies the processes involved in the formation and eruptive activity of volcanoes and their current and historic eruptions, known as volcanology.
- Avolcanologist
- Bvolcanology
- Cvolcano
11Are the symptoms of COVID-19 different in children than in adults?
No. The symptoms of COVID-19 are similar in [blank_start]children[blank_end] and adults. However, children with confirmed COVID-19 have generally presented with mild symptoms. Reported symptoms in children include cold-like symptoms, such as fever, [blank_start]runny nose[blank_end], and cough. Vomiting and diarrhea have also been reported. It’s not known yet whether some children may be at higher [blank_start]risk[blank_end] for severe illness, for example, children with underlying medical conditions and special healthcare needs. There is much more to be learned about how the disease impacts children.
- Achildren
- Brisk
- Crunny nose
12What word refers to the formation of the mountains?
- ARange
- BOrogeny
- CTectonic Plates
13What influences do the Andean Mountains have on the biodiversity of Ecuador?
It is because of many levels of [blank_start]altitudes[blank_end] created by the mountains that allow for the different climates, plants, and animals.
The Andes have created immense biodiversity in the moorlands (Páramos), valleys, Coast and Sierra.- Aaltitudes
- Bclimates
- Cbiodiversity
14What are epeirogenic movements?
They are slow vertical movements of uprising and dips of the tectonic plates. They form [blank_start]continents[blank_end].- Aoceans
- Bcontinents
- Chouses
15What is El Niño?
El Niño is characterized by unusually cold temperatures in the Equatorial Pacific.
- ATrue
- BFalse
16What is El Niño?
El Niño is characterized by unusually warm ocean [blank_start]temperatures[blank_end] in the Equatorial Pacific.
El Niño is an oscillation of the ocean-atmosphere system in the tropical Pacific having important consequences for weather around the globe.- APacific
- Bcurrent
- Ctemperatures
17The [blank_start]climate[blank_end] is the weather conditions of a a region ( temperature, moisture etc) .
- Aclimate
18This is a cold water current which does not promote evaporation or cloud formation
- AEl Niño
- BNatural phenomenon
- CHumboldt
19What are climate catastrophes?
Extremely bad events that causes a lot of suffering or [blank_start]destruction[blank_end] due to changes in weather.
- ACOVID-19
- Bdestruction
- Csymptoms
20How do chemical compounds cause climate change?
Increases levels of [blank_start]CO2[blank_end], raise the Earth´s surface temperature.
- AH2O
- BCO2
- CO2
