Seasons & Earth's Tilt
What causes Earth to have seasons?
Earth's tilt as it revolves around the sun
What force causes ocean tides?
Gravity
Which sphere includes plants and animals?
Biosphere
What is the outermost layer of the Earth?
Crust
Which rock type forms from magma or lava?
Igneous
How many degrees is Earth's tilt?
23.5
Which object has the strongest effect on Earth’s tides?
The moon
Water vapor is a part of which sphere?
Hydrosphere
Which layer is the hottest?
Inner Core
Which rock type often contains layers or fossils?
Sedimentary
Which season occurs when a hemisphere receives the most direct sunlight?
Summer
What type of tide occurs when the Sun, Moon, and Earth are in a straight line?
Spring Tide
Which sphere contains clouds, gases, and weather?
Atmosphere
Which layer is liquid and helps create Earth’s magnetic field?
Outer Core
Heat and pressure change rocks into which type?
Metamorphic
True or False: Earth’s distance from the Sun causes the seasons. Explain.
False; Earth’s tilt causes seasons
How are neap tides different from spring tides?
The sun, Earth, and moon are perpendicular or form a 90-degree angle.
Soil, rocks, and mountains belong to which Earth sphere?
Geosphere
Put the layers in order from the center outward.
Inner core → Outer core → Mantle → Crust
What processes can change sedimentary rock into metamorphic rock?
Heat and Pressure
A city at 40°N latitude experiences longer daylight hours in June than in December. Explain why this happens using Earth’s tilt and revolution.
In June, the city is pointing towards the sun and away in December. Or the city receives direct sunlight in June and indirect sunlight in December.
A coastal town notices weaker tides for several days. Based on the positions of the Sun, Earth, and Moon, predict what type of tide is occurring and explain why.
Neap tide; the Sun and Moon are pulling at right angles, reducing tidal range
A fish swimming in a lake is an example of which TWO Earth spheres are interacting?
Biosphere and Hydrosphere
The tectonic plates can be found in which layer of Earth?
The mantle
Describe how an igneous rock could eventually become a sedimentary rock.
Through weathering, compaction, and cementation
