Which of Earth's forces (agent) is responsible for creating the landform below? (V-shaped valley?

Moving water (fast moving rivers)
Why is the Sun apart of the water cycle?

The Sun starts (powers) the water cycle by evaporating the water
Which arrow shows the movement on Earth that causes Day and Night?

4-rotation
You are given two similar substances. One is powdered sugar and the other is powdered chalk. How can you use the substances physical properties to determine which is which?

Solubility: sugar will dissolve, chalk will not dissolve
Whats the independent variable in an experiment?
What's different, tested, compared
A students uses a battery powered flashlight in his home when the power goes out. How is energy being transformed between the battery and the bulb of the flashlight?

Chemical to electrical to light
What happened to the dead plants and animals?
Became fossil fuels (coal, oil, natural gas) from the heat and pressure of the layers
Name the types of precipitation
Rain, Snow, Sleet, Hail
How long does Earth's revolution take?
365 days (1 year)
Name at least TWO properties the items have in common?

electrical conductor, magnetic, more dense, metal
Doug is paddling to get to land. Describe what is happening

Doug is paddling with more force forward than the river is flowing backward. Forces are unbalanced; Doug is moving closer to land
Marta has a pinwheel like the one shown below. While helping her mom with dinner, she discovers that the steam produced when boiling water makes the pinwheel spin. Which energy transformation is happening to make the pinwheel move?
thermal to mechanical
Which force (wind, water, ice) and process (weathering, erosion, deposition) formed this landform?

Water (river) depostion; water dropping the sedments when it slows down
Which statement describes Climate and WHY?
The air pressure is higher today than it was yesterday.
The average high temperature this week is 56 degree fahrenheit.
The annual average temperature has slowly increased over that last 50 years.
The wind storm yesterday damaged trees.
3: annual, average, 50 years
On which side of a house in Texas should a window be placed so that the people inside can watch the sunset every day?
West
Which mixture(s) do all of the ingredients keep their physical properties?
Mixture 2 and 4; none dissolves
A student designs an experiment to test how the width of elastic affects the elastic's ability to stretch. The student uses 4 pieces of elastic with different widths (thickness). Blocks of different masses are attached to each elastic as pictured.
What should be done to improve this experiment?

Use blocks of equal mass. Elastic width is already different, can only have 1 independent variable
A student creates the circuit shown. Which bulbs will produce light?

Only lightbulb 3
Which TWO Texas land formations are correctly paired with the force that created them?
1. A canyon at Palo Duro Canyon State Park was formed by a river.
2. A series of caves formed by deposition at Longhorn Cavern State Park.
3. A delta at the end of the Guadalupe River was formed by wind.
4. A sand dune at Monahans Sandhills State Park was formed by wind.
5. A rock formation with layers on Mustang Island was formed by ice.
1 and 4
Canyons created by water
Sand dunes created by wind

B
weather-tomorrow
climate-coldest temperatures/40 years
When are shadows the longest and why?
Sunrise and Sunset because the Sun is low in the sky
4 students are having a conversation about a balloon they see floating through the air. Which student is correct?

Alex
Name TWO forces that are happening in this picture

unbalanced forces: push of him throwing the ball and gravity will pull the ball down to the ground
What are the properties of an object that will produce a good reflection of light? (other than a mirror or glass)-Must list 2
smooth, shiny, metal, surface of water
What are the steps (IN ORDER) of sedimentary rock formation?

weathering, erosion, deposition, compaction and cementation
or
break, move, drop, pressure, glue
Study the model of the water cycle. What part of the model represents:
The Sun? Condensation? Precipitation?

Sun- the lamp
Condensation- tiny droplets forming at the top of bottle
Precipitation- drops running down the side of the bottle
Around what time of day is pictured based on the sundial?

3:00 PM
The sun would appear between W and Z
Explain what is happening in this picture
Condensation. The air in the room is warmer than the bottle; when the air (gas) comes in contact with the bottle it turns back into a liquid

Students 1 and 3
Identify all 3 light interactions

1-refract, 2-absorb, 3-reflect
