UNIVERSE AND SOLAR SYSTEM
It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now.
The Big Bang Theory
AGREE OR DISAGREE
Over 97 percent of Earth's water is in the ocean.
Name the three layers of the Earth.
Crust, mantle and core
The layer of Earth with the air & gases.
What is the atmosphere?
These are the three types of rocks.
Igneous, sedimentary and metamorphic rocks
TRUE OR FALSE: The nebular theory is a variation of the Big Bang theory, in which the Universe goes through successive periods of expansion and contraction.
FALSE (Pulsating Theory)
These are the movements of the Earth.
Rotation and Revolution
What is the outer layer of the Earth called?
crust
These are the Earth's systems.
Hydrosphere, lithosphere, biosphere and atmosphere
True or false:
Rocks can be reproduced.
False. Rocks cannot be reproduced. Rocks are formed through natural processes over geological time scales and cannot be replicated or reproduced artificially.
These are the two continents that formed after the Pangaea broke apart.
Laurasia and Gondwanaland
What is the middle layer of the Earth called?
Mantle
The thickest layer of the Earth and thinner layer of the earth.
The mantle is the thickest layer, while the crust is the thinnest layer.
How many layers make up the Earth's atmosphere, and what are their names?
5 layers of the atmosphere
Troposphere, stratosphere, mesosphere, thermosphere and exosphere
Give three characteristics of rocks.
Naturally occurring, inorganic, solid, has definite chemical composition and has an ordered internal structure.
In order, name the planets in the solar system.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune
What causes the seasons on Earth?
This tilt, combined with its revolution around the Sun
What is the main composition of the Earth's inner core?
Both the inner and outer cores consist primarily of iron and nickel.
How do the atmosphere and hydrosphere interact to create weather patterns?
The hydrosphere and the atmosphere are closely interconnected, shaping Earth's climate and driving weather patterns.
These are the special properties of minerals.
Magnetism, taste, effervescence and feel
These are the four pieces of evidence found by Alfred Wegener to support the continental drift theory.
Rock formations, fossil evidence, coal deposits and the continental jigsaw puzzle
How old is the Earth estimated to be?
4.5 billion years
How do scientists study the composition of Earth's layers if we cannot physically access them?
Seismic activity is a way for scientists to understand the Earth's layers without having to find a way to actually dig down and examine them. (Through Seismic Waves)
What role does the biosphere play in the carbon cycle?
Carbon is found in the biosphere stored in plants and trees. Plants use carbon dioxide from the atmosphere to make the building blocks of food during photosynthesis. Carbon is found in the hydrosphere dissolved in ocean water and lakes. Carbon is used by many organisms to produce shells.
Explain the three different types of rocks are formed.
IGNEOUS ROCKS: These rocks form from the cooling and solidification of molten magma or lava.
SEDIMENTARY ROCKS: These rocks form from the accumulation, compaction, and cementation of sediments, which can be fragments of other rocks, minerals, or organic material.
METAMORPHIC ROCKS: These rocks form from the alteration of existing rocks (igneous, sedimentary, or other metamorphic rocks) through heat, pressure, and/or chemically active fluids.
