Each question below carries 10 marks.
1) How does the cryosphere help regulate Earth's temperature?
2) What kind of organisms are found in oceanic trenches? Describe.
3) Explain how an Estuary can support a wide variety of food webs.
4) List out and describe the factors that help meteorologists forecast weather.
Answer:
ans 1 ; It also includes frozen rivers and lakes, which mainly occur in polar areas. The components of the cryosphere play an important role in the Earth's climate. Snow and ice reflect heat from the sun, helping to regulate our planet's temperature.
ans 2 ; Deep-sea trench, also called oceanic trench, any long, narrow, steep-sided depression in the ocean bottom in which occur the maximum oceanic depths, approximately 7,300 to more than 11,000 metres (24,000 to 36,000 feet). They typically form in locations where one tectonic plate subducts under another.
ans 3 ; The calm waters provide a safe area for small fish, shellfish, migrating birds and shore animals. The waters are rich in nutrients such as plankton and bacteria. Decomposing plant matter, called detritus, provides food for many species. ... This means the estuary must support a wide variety of food webs.
ans 4 ; Weather can be defined as the condition of the atmosphere at any given time and place. Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.

Evaluate (Two-fifths) cubed. Check all that apply.
The exponent is Two-fifths.
The expanded form is (Two-fifths) (two-fifths) (two-fifths).
The expanded form is StartFraction 2 times 2 times 2 Over 5 EndFraction.
(Two-fifths) cubed = StartFraction 6 Over 15 EndFraction
(Two-fifths) cubed = StartFraction 8 Over 125 EndFraction

As radiation from the sun reaches the earth, the energy is-
A ) Immediately radiated back into space.
B ) Absorbed by only the oceans
C ) Radiated, reflected, and absorbed
D ) Only reflected by clouds in the atmosphere
Answer:C
Explanation:All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Answer: A) The amount of heat radiated from the atmosphere to the surface (sometimes called “back radiation”) is equivalent to 100 percent of the incoming solar energy.
B)On its northward journey, the water at the surface absorbs gases like carbon dioxide and chlorofluorocarbons (CFCs) – the latter are, to a large extent, the gases responsible for the ozone hole over Antarctica – as well as excess heat from the atmosphere
C)Water droplets and ice crystals that make up clouds scatter light equally at all wavelengths and therefore appear white. Reflection of solar radiation occurs when the radiation is sent directly backward from a surface. The fraction (or percentage) of radiation reflected back is known as albedo.
D)Clouds cool Earth's surface by reflecting incoming sunlight. ... Clouds warm or cool Earth's atmosphere by absorbing heat emitted from the surface and radiating it to space. Clouds warm and dry Earth's atmosphere and supply water to the surface by forming precipitation

1. What impact did Portugal have on Latin America? Is it still evident today?
2. How did African slavery change the culture of much of the Caribbean and South America?
3. How did Spain have a dramatic impact on most of Latin America that is still evident today?
Answer:
Explanation:
1: Portugal still greatly impacts Latin America, specifically Brazil. One of Brazil's official languages is Portuguese
2: Slavery has also greatly impacted the Caribbean and Latin America, with many people being of African descent in this countries, and countries like Haiti were created because of slavery.
3: Spain pretty much created Latin America, because most countries were colonized by Spain, and much of Spanish culture and the Spanish language remains.
Write down your observations of how the lava flows.
Fluid basalt flows can extend tens of kilometers from an erupting vent. The leading edges of basalt flows can travel as fast as 10 km/h (6 mph) on steep slopes but they typically advance less than 1 km/h (0.27 m/s or about 1 ft/s) on gentle slopes.
Which of the following is an example of balanced forces?
A.
A light bulb filament glows when a current moves through a wire.
B.
A person in a hot air balloon ignites the burner, which makes the balloon rise.
C.
A seesaw remains stationary when two students of equal weight sit on the ends.
D.
A driver slams on the car brake, and the car comes to a stop.
A seesaw remains stationary when two students of equal weight sit on the ends
c
Answer:
the answer is c.
Explanation:
a balanced force is a constant motion, or when the object does not move. because the children have the same weight, they can manage the seesaw to stay still.
